For any issue, there are fundamentally three -ways an individual can contribute: - -1. By opening the issue for discussion: For instance, if you believe that you - have uncovered a bug in Node.js, creating a new issue in the `nodejs/node` - issue tracker is the way to report it. -2. By helping to triage the issue: This can be done either by providing - supporting details (a test case that demonstrates a bug), or providing - suggestions on how to address the issue. -3. By helping to resolve the issue: Typically this is done either in the form - of demonstrating that the issue reported is not a problem after all, or more - often, by opening a Pull Request that changes some bit of something in - `nodejs/node` in a concrete and reviewable manner. - -### Asking for General Help - -Because the level of activity in the `nodejs/node` repository is so high, -questions or requests for general help using Node.js should be directed at -the [Node.js help repository][]. - -### Discussing non-technical topics - -Discussion of non-technical topics (such as intellectual property and trademark) -should be directed to the [Technical Steering Committee (TSC) repository][]. - -### Submitting a Bug Report - -When opening a new issue in the `nodejs/node` issue tracker, users will be -presented with a basic template that should be filled in. - -```markdown - - -* **Version**: -* **Platform**: -* **Subsystem**: - - -``` - -If you believe that you have uncovered a bug in Node.js, please fill out this -form, following the template to the best of your ability.

Some contributors may have differing opinions about the issue, -including whether the behavior being seen is a bug or a feature. This discussion -is part of the process and should be kept focused, helpful, and professional. - -Short, clipped responses—that provide neither additional context nor supporting -detail—are not helpful or professional. To many, such responses are simply -annoying and unfriendly. - -Contributors are encouraged to help one another make forward progress as much -as possible, empowering one another to solve issues collaboratively. If you -choose to comment on an issue that you feel either is not a problem that needs -to be fixed, or if you encounter information in an issue that you feel is -incorrect, explain *why* you feel that way with additional supporting context, -and be willing to be convinced that you may be wrong. By doing so, we can often -reach the correct outcome much faster. - -### Resolving a Bug Report - -In the vast majority of cases, issues are resolved by opening a Pull Request. -The process for opening and reviewing a Pull Request is similar to that of -opening and triaging issues, but carries with it a necessary review and approval -workflow that ensures that the proposed changes meet the minimal quality and -functional guidelines of the Node.js project. - -## Pull Requests +## [Pull Requests](./doc/guides/contributing/pull-requests.md) Pull Requests are the way concrete changes are made to the code, documentation, dependencies, and tools contained in the `nodejs/node` repository. -There are two fundamental components of the Pull Request process: one concrete -and technical, and one more process oriented. The concrete and technical -component involves the specific details of setting up your local environment -so that you can make the actual changes. This is where we will start. - -### Dependencies - -Node.js has several bundled dependencies in the *deps/* and the *tools/* -directories that are not part of the project proper. Changes to files in those -directories should be sent to their respective projects. Do not send a patch to -Node.js. We cannot accept such patches. - -In case of doubt, open an issue in the -[issue tracker](https://github.com/nodejs/node/issues/) or contact one of the -[project Collaborators](https://github.com/nodejs/node/#current-project-team-members). -Node.js has two IRC channels: -[#Node.js](https://webchat.freenode.net/?channels=node.js) for general help and -questions, and -[#Node-dev](https://webchat.freenode.net/?channels=node-dev) for development of -Node.js core specifically. - -### Setting up your local environment - -To get started, you will need to have `git` installed locally. Depending on -your operating system, there are also a number of other dependencies required. -These are detailed in the [Building guide][]. - -Once you have `git` and are sure you have all of the necessary dependencies, -it's time to create a fork. - -Before getting started, it is recommended to configure `git` so that it knows -who you are: - -```text -$ git config --global user.name "J. Random User" -$ git config --global user.email "j.random.user@example.com" -``` -Please make sure this local email is also added to your -[GitHub email list](https://github.com/settings/emails) so that your commits -will be properly associated with your account and you will be promoted -to Contributor once your first commit is landed. - -#### Step 1: Fork - -Fork the project [on GitHub](https://github.com/nodejs/node) and clone your fork -locally. - -```text -$ git clone git@github.com:username/node.git -$ cd node -$ git remote add upstream https://github.com/nodejs/node.git -$ git fetch upstream -``` - -#### Step 2: Branch - -As a best practice to keep your development environment as organized as -possible, create local branches to work within. These should also be created -directly off of the `master` branch. - -```text -$ git checkout -b my-branch -t upstream/master -``` - -### The Process of Making Changes - -#### Step 3: Code - -The vast majority of Pull Requests opened against the `nodejs/node` -repository includes changes to either the C/C++ code contained in the `src` -directory, the JavaScript code contained in the `lib` directory, the -documentation in `docs/api` or tests within the `test` directory. - -If you are modifying code, please be sure to run `make lint` from time to -time to ensure that the changes follow the Node.js code style guide. - -Any documentation you write (including code comments and API documentation) -should follow the [Style Guide](doc/STYLE_GUIDE.md). Code samples included -in the API docs will also be checked when running `make lint` (or -`vcbuild.bat lint` on Windows). - -For contributing C++ code, you may want to look at the -[C++ Style Guide](CPP_STYLE_GUIDE.md). - -#### Step 4: Commit - -It is a recommended best practice to keep your changes as logically grouped -as possible within individual commits. There is no limit to the number of -commits any single Pull Request may have, and many contributors find it easier -to review changes that are split across multiple commits. - -```text -$ git add my/changed/files -$ git commit -``` - -Note that multiple commits often get squashed when they are landed (see the -notes about [commit squashing](#commit-squashing)). - -##### Commit message guidelines - -A good commit message should describe what changed and why. - -1. The first line should: - - contain a short description of the change (preferably 50 characters or less, - and no more than 72 characters) - - be entirely in lowercase with the exception of proper nouns, acronyms, and - the words that refer to code, like function/variable names - - be prefixed with the name of the changed subsystem and start with an - imperative verb. Check the output of `git log --oneline files/you/changed` to - find out what subsystems your changes touch. - - Examples: - - `net: add localAddress and localPort to Socket` - - `src: fix typos in node_lttng_provider.h` - - -2. Keep the second line blank. -3. Wrap all other lines at 72 columns. - -4. If your patch fixes an open issue, you can add a reference to it at the end -of the log. Use the `Fixes:` prefix and the full issue URL. For other references -use `Refs:`. - - Examples: - - `Fixes: https://github.com/nodejs/node/issues/1337` - - `Refs: http://eslint.org/docs/rules/space-in-parens.html` - - `Refs: https://github.com/nodejs/node/pull/3615` - -5. If your commit introduces a breaking change (`semver-major`), it should -contain an explanation about the reason of the breaking change, which -situation would trigger the breaking change and what is the exact change. - -Breaking changes will be listed in the wiki with the aim to make upgrading -easier. Please have a look at [Breaking Changes](https://github.com/nodejs/node/wiki/Breaking-changes-between-v4-LTS-and-v6-LTS) -for the level of detail that's suitable. - -Sample complete commit message: - -```txt -subsystem: explain the commit in one line - -Body of commit message is a few lines of text, explaining things -in more detail, possibly giving some background about the issue -being fixed, etc. - -The body of the commit message can be several paragraphs, and -please do proper word-wrap and keep columns shorter than about -72 characters or so. That way, `git log` will show things -nicely even when it is indented. - -Fixes: https://github.com/nodejs/node/issues/1337 -Refs: http://eslint.org/docs/rules/space-in-parens.html -``` - -If you are new to contributing to Node.js, please try to do your best at -conforming to these guidelines, but do not worry if you get something wrong. -One of the existing contributors will help get things situated and the -contributor landing the Pull Request will ensure that everything follows -the project guidelines. - -#### Step 5: Rebase - -As a best practice, once you have committed your changes, it is a good idea -to use `git rebase` (not `git merge`) to synchronize your work with the main -repository. - -```text -$ git fetch upstream -$ git rebase upstream/master -``` - -This ensures that your working branch has the latest changes from `nodejs/node` -master. - -#### Step 6: Test - -Bug fixes and features should always come with tests. A -[guide for writing tests in Node.js](./doc/guides/writing-tests.md) has been -provided to make the process easier. Looking at other tests to see how they -should be structured can also help. - -The `test` directory within the `nodejs/node` repository is complex and it is -often not clear where a new test file should go. When in doubt, add new tests -to the `test/parallel/` directory and the right location will be sorted out -later. - -Before submitting your changes in a Pull Request, always run the full Node.js -test suite. To run the tests (including code linting) on Unix / macOS: - -```text -$ ./configure && make -j4 test -``` - -And on Windows: - -```text -> vcbuild test -``` - -(See the [BUILDING.md](./BUILDING.md) for more details.) - -Make sure the linter does not report any issues and that all tests pass. Please -do not submit patches that fail either check. - -If you want to run the linter without running tests, use -`make lint`/`vcbuild lint`. It will run both JavaScript linting and -C++ linting. - -If you are updating tests and just want to run a single test to check it: - -```text -$ python tools/test.py -J --mode=release parallel/test-stream2-transform -``` - -You can execute the entire suite of tests for a given subsystem -by providing the name of a subsystem: - -```text -$ python tools/test.py -J --mode=release child-process -``` - -If you want to check the other options, please refer to the help by using -the `--help` option - -```text -$ python tools/test.py --help -``` - -You can usually run tests directly with node: - -```text -$ ./node ./test/parallel/test-stream2-transform.js -``` - -Remember to recompile with `make -j4` in between test runs if you change code in -the `lib` or `src` directories. - -##### Test Coverage - -It's good practice to ensure any code you add or change is covered by tests. -You can do so by running the test suite with coverage enabled: - -```text -$ ./configure --coverage && make coverage -``` - -A detailed coverage report will be written to `coverage/index.html` for -JavaScript coverage and to `coverage/cxxcoverage.html` for C++ coverage. - -_Note that generating a test coverage report can take several minutes._ - -To collect coverage for a subset of tests you can set the `CI_JS_SUITES` and -`CI_NATIVE_SUITES` variables: - -```text -$ CI_JS_SUITES=child-process CI_NATIVE_SUITES= make coverage -``` - -The above command executes tests for the `child-process` subsystem and -outputs the resulting coverage report. - -Running tests with coverage will create and modify several directories -and files. To clean up afterwards, run: - -```text -make coverage-clean -./configure && make -j4. -``` - -#### Step 7: Push - -Once you are sure your commits are ready to go, with passing tests and linting, -begin the process of opening a Pull Request by pushing your working branch to -your fork on GitHub. - -```text -$ git push origin my-branch -``` - -#### Step 8: Opening the Pull Request - -From within GitHub, opening a new Pull Request will present you with a template -that should be filled out: - -```markdown - - -##### Checklist - - -- [ ] `make -j4 test` (UNIX), or `vcbuild test` (Windows) passes -- [ ] tests and/or benchmarks are included -- [ ] documentation is changed or added -- [ ] commit message follows [commit guidelines](https://github.com/nodejs/node/blob/master/CONTRIBUTING.md#commit-message-guidelines) - -##### Affected core subsystem(s) - -``` - -Please try to do your best at filling out the details, but feel free to skip -parts if you're not sure what to put. - -Once opened, Pull Requests are usually reviewed within a few days. - -#### Step 9: Discuss and update - -You will probably get feedback or requests for changes to your Pull Request. -This is a big part of the submission process so don't be discouraged! Some -contributors may sign off on the Pull Request right away, others may have -more detailed comments or feedback. This is a necessary part of the process -in order to evaluate whether the changes are correct and necessary. - -To make changes to an existing Pull Request, make the changes to your local -branch, add a new commit with those changes, and push those to your fork. -GitHub will automatically update the Pull Request. - -```text -$ git add my/changed/files -$ git commit -$ git push origin my-branch -``` - -It is also frequently necessary to synchronize your Pull Request with other -changes that have landed in `master` by using `git rebase`: - -```text -$ git fetch --all -$ git rebase origin/master -$ git push --force-with-lease origin my-branch -``` - -**Important:** The `git push --force-with-lease` command is one of the few ways -to delete history in `git`. Before you use it, make sure you understand the -risks. If in doubt, you can always ask for guidance in the Pull Request or on -[IRC in the #node-dev channel][]. - -If you happen to make a mistake in any of your commits, do not worry. You can -amend the last commit (for example if you want to change the commit log). - -```text -$ git add any/changed/files -$ git commit --amend -$ git push --force-with-lease origin my-branch -``` - -There are a number of more advanced mechanisms for managing commits using -`git rebase` that can be used, but are beyond the scope of this guide. - -Feel free to post a comment in the Pull Request to ping reviewers if you are -awaiting an answer on something. If you encounter words or acronyms that -seem unfamiliar, refer to this -[glossary](https://sites.google.com/a/chromium.org/dev/glossary). - -##### Approval and Request Changes Workflow - -All Pull Requests require "sign off" in order to land. Whenever a contributor -reviews a Pull Request they may find specific details that they would like to -see changed or fixed. These may be as simple as fixing a typo, or may involve -substantive changes to the code you have written. In general, such requests -are intended to be helpful, but at times may come across as abrupt or unhelpful, -especially requests to change things that do not include concrete suggestions -on *how* to change them. - -Try not to be discouraged. If you feel that a particular review is unfair, -say so, or contact one of the other contributors in the project and seek their -input. Often such comments are the result of the reviewer having only taken a -short amount of time to review and are not ill-intended. Such issues can often -be resolved with a bit of patience. That said, reviewers should be expected to -be helpful in their feedback, and feedback that is simply vague, dismissive and -unhelpful is likely safe to ignore. - -#### Step 10: Landing - -In order to land, a Pull Request needs to be reviewed and [approved][] by -at least one Node.js Collaborator and pass a -[CI (Continuous Integration) test run][]. After that, as long as there are no -objections from other contributors, the Pull Request can be merged. If you find -your Pull Request waiting longer than you expect, see the -[notes about the waiting time](#waiting-until-the-pull-request-gets-landed). - -When a collaborator lands your Pull Request, they will post -a comment to the Pull Request page mentioning the commit(s) it -landed as. GitHub often shows the Pull Request as `Closed` at this -point, but don't worry. If you look at the branch you raised your -Pull Request against (probably `master`), you should see a commit with -your name on it. Congratulations and thanks for your contribution! - -### Reviewing Pull Requests - -All Node.js contributors who choose to review and provide feedback on Pull -Requests have a responsibility to both the project and the individual making the -contribution. Reviews and feedback must be helpful, insightful, and geared -towards improving the contribution as opposed to simply blocking it. If there -are reasons why you feel the PR should not land, explain what those are. Do not -expect to be able to block a Pull Request from advancing simply because you say -"No" without giving an explanation. Be open to having your mind changed. Be open -to working with the contributor to make the Pull Request better. - -Reviews that are dismissive or disrespectful of the contributor or any other -reviewers are strictly counter to the [Code of Conduct][]. - -When reviewing a Pull Request, the primary goals are for the codebase to improve -and for the person submitting the request to succeed. Even if a Pull Request -does not land, the submitters should come away from the experience feeling like -their effort was not wasted or unappreciated. Every Pull Request from a new -contributor is an opportunity to grow the community. - -#### Review a bit at a time. - -Do not overwhelm new contributors. - -It is tempting to micro-optimize and make everything about relative performance, -perfect grammar, or exact style matches. Do not succumb to that temptation. - -Focus first on the most significant aspects of the change: - -1. Does this change make sense for Node.js? -2. Does this change make Node.js better, even if only incrementally? -3. Are there clear bugs or larger scale issues that need attending to? -4. Is the commit message readable and correct? If it contains a breaking change is it clear enough? - -When changes are necessary, *request* them, do not *demand* them, and do not -assume that the submitter already knows how to add a test or run a benchmark. - -Specific performance optimization techniques, coding styles and conventions -change over time. The first impression you give to a new contributor never does. - -Nits (requests for small changes that are not essential) are fine, but try to -avoid stalling the Pull Request. Most nits can typically be fixed by the -Node.js Collaborator landing the Pull Request but they can also be an -opportunity for the contributor to learn a bit more about the project. - -It is always good to clearly indicate nits when you comment: e.g. -`Nit: change foo() to bar(). But this is not blocking.` - -#### Be aware of the person behind the code - -Be aware that *how* you communicate requests and reviews in your feedback can -have a significant impact on the success of the Pull Request. Yes, we may land -a particular change that makes Node.js better, but the individual might just -not want to have anything to do with Node.js ever again. The goal is not just -having good code. - -#### Respect the minimum wait time for comments - -There is a minimum waiting time which we try to respect for non-trivial -changes, so that people who may have important input in such a distributed -project are able to respond. - -For non-trivial changes, Pull Requests must be left open for *at least* 48 -hours during the week, and 72 hours on a weekend. In most cases, when the -PR is relatively small and focused on a narrow set of changes, these periods -provide more than enough time to adequately review. Sometimes changes take far -longer to review, or need more specialized review from subject matter experts. -When in doubt, do not rush. - -Trivial changes, typically limited to small formatting changes or fixes to -documentation, may be landed within the minimum 48 hour window. - -#### Abandoned or Stalled Pull Requests - -If a Pull Request appears to be abandoned or stalled, it is polite to first -check with the contributor to see if they intend to continue the work before -checking if they would mind if you took it over (especially if it just has -nits left). When doing so, it is courteous to give the original contributor -credit for the work they started (either by preserving their name and email -address in the commit log, or by using an `Author: ` meta-data tag in the -commit. - -#### Approving a change - -Any Node.js core Collaborator (any GitHub user with commit rights in the -`nodejs/node` repository) is authorized to approve any other contributor's -work. Collaborators are not permitted to approve their own Pull Requests. - -Collaborators indicate that they have reviewed and approve of the changes in -a Pull Request either by using GitHub's Approval Workflow, which is preferred, -or by leaving an `LGTM` ("Looks Good To Me") comment. - -When explicitly using the "Changes requested" component of the GitHub Approval -Workflow, show empathy. That is, do not be rude or abrupt with your feedback -and offer concrete suggestions for improvement, if possible. If you're not -sure *how* a particular change can be improved, say so. - -Most importantly, after leaving such requests, it is courteous to make yourself -available later to check whether your comments have been addressed. - -If you see that requested changes have been made, you can clear another -collaborator's `Changes requested` review. - -Change requests that are vague, dismissive, or unconstructive may also be -dismissed if requests for greater clarification go unanswered within a -reasonable period of time. - -If you do not believe that the Pull Request should land at all, use -`Changes requested` to indicate that you are considering some of your comments -to block the PR from landing. When doing so, explain *why* you believe the -Pull Request should not land along with an explanation of what may be an -acceptable alternative course, if any. - -#### Accept that there are different opinions about what belongs in Node.js - -Opinions on this vary, even among the members of the Technical Steering -Committee. - -One general rule of thumb is that if Node.js itself needs it (due to historic -or functional reasons), then it belongs in Node.js. For instance, `url` -parsing is in Node.js because of HTTP protocol support. - -Also, functionality that either cannot be implemented outside of core in any -reasonable way, or only with significant pain. - -It is not uncommon for contributors to suggest new features they feel would -make Node.js better. These may or may not make sense to add, but as with all -changes, be courteous in how you communicate your stance on these. Comments -that make the contributor feel like they should have "known better" or -ridiculed for even trying run counter to the [Code of Conduct][]. - -#### Performance is not everything - -Node.js has always optimized for speed of execution. If a particular change -can be shown to make some part of Node.js faster, it's quite likely to be -accepted. Claims that a particular Pull Request will make things faster will -almost always be met by requests for performance [benchmark results][] that -demonstrate the improvement. - -That said, performance is not the only factor to consider. Node.js also -optimizes in favor of not breaking existing code in the ecosystem, and not -changing working functional code just for the sake of changing. - -If a particular Pull Request introduces a performance or functional -regression, rather than simply rejecting the Pull Request, take the time to -work *with* the contributor on improving the change. Offer feedback and -advice on what would make the Pull Request acceptable, and do not assume that -the contributor should already know how to do that. Be explicit in your -feedback. - -#### Continuous Integration Testing - -All Pull Requests that contain changes to code must be run through -continuous integration (CI) testing at [https://ci.nodejs.org/][]. - -Only Node.js core Collaborators with commit rights to the `nodejs/node` -repository may start a CI testing run. The specific details of how to do -this are included in the new Collaborator [Onboarding guide][]. - -Ideally, the code change will pass ("be green") on all platform configurations -supported by Node.js (there are over 30 platform configurations currently). -This means that all tests pass and there are no linting errors. In reality, -however, it is not uncommon for the CI infrastructure itself to fail on -specific platforms or for so-called "flaky" tests to fail ("be red"). It is -vital to visually inspect the results of all failed ("red") tests to determine -whether the failure was caused by the changes in the Pull Request. - -## Additional Notes - -### Commit Squashing - -When the commits in your Pull Request land, they may be squashed -into one commit per logical change. Metadata will be added to the commit -message (including links to the Pull Request, links to relevant issues, -and the names of the reviewers). The commit history of your Pull Request, -however, will stay intact on the Pull Request page. - -For the size of "one logical change", -[0b5191f](https://github.com/nodejs/node/commit/0b5191f15d0f311c804d542b67e2e922d98834f8) -can be a good example. It touches the implementation, the documentation, -and the tests, but is still one logical change. In general, the tests should -always pass when each individual commit lands on the master branch. - -### Getting Approvals for Your Pull Request - -A Pull Request is approved either by saying LGTM, which stands for -"Looks Good To Me", or by using GitHub's Approve button. -GitHub's Pull Request review feature can be used during the process. -For more information, check out -[the video tutorial](https://www.youtube.com/watch?v=HW0RPaJqm4g) -or [the official documentation](https://help.github.com/articles/reviewing-changes-in-pull-requests/). - -After you push new changes to your branch, you need to get -approval for these new changes again, even if GitHub shows "Approved" -because the reviewers have hit the buttons before. - -### CI Testing - -Every Pull Request needs to be tested -to make sure that it works on the platforms that Node.js -supports. This is done by running the code through the CI system. - -Only a Collaborator can start a CI run. Usually one of them will do it -for you as approvals for the Pull Request come in. -If not, you can ask a Collaborator to start a CI run. - -### Waiting Until the Pull Request Gets Landed - -A Pull Request needs to stay open for at least 48 hours (72 hours on a -weekend) from when it is submitted, even after it gets approved and -passes the CI. This is to make sure that everyone has a chance to -weigh in. If the changes are trivial, collaborators may decide it -doesn't need to wait. A Pull Request may well take longer to be -merged in. All these precautions are important because Node.js is -widely used, so don't be discouraged! - -### Check Out the Collaborator's Guide - -If you want to know more about the code review and the landing process, -you can take a look at the -[collaborator's guide](https://github.com/nodejs/node/blob/master/COLLABORATOR_GUIDE.md). - -### Helpful Resources - -The following additional resources may be of assistance: - -* [How to create a Minimal, Complete, and Verifiable example](https://stackoverflow.com/help/mcve) -* [core-validate-commit](https://github.com/evanlucas/core-validate-commit) - - A utility that ensures commits follow the commit formatting guidelines. +* [Dependencies](./doc/guides/contributing/pull-requests.md#dependencies) +* [Setting up your local environment](./doc/guides/contributing/pull-requests.md#setting-up-your-local-environment) +* [The Process of Making Changes](./doc/guides/contributing/pull-requests.md#the-process-of-making-changes) +* [Reviewing Pull Requests](./doc/guides/contributing/pull-requests.md#reviewing-pull-requests) +* [Additional Notes](./doc/guides/contributing/pull-requests.md#additional-notes) ## Developer's Certificate of Origin 1.1 @@ -853,14 +69,3 @@ By making a contribution to this project, I certify that: personal information I submit with it, including my sign-off) is maintained indefinitely and may be redistributed consistent with this project or the open source license(s) involved. - -[approved]: #getting-approvals-for-your-pull-request -[benchmark results]: ./doc/guides/writing-and-running-benchmarks.md -[Building guide]: ./BUILDING.md -[CI (Continuous Integration) test run]: #ci-testing -[Code of Conduct]: https://github.com/nodejs/admin/blob/master/CODE_OF_CONDUCT.md -[https://ci.nodejs.org/]: https://ci.nodejs.org/ -[IRC in the #node-dev channel]: https://webchat.freenode.net?channels=node-dev&uio=d4 -[Node.js help repository]: https://github.com/nodejs/help/issues -[Onboarding guide]: ./doc/onboarding.md -[Technical Steering Committee (TSC) repository]: https://github.com/nodejs/TSC/issues diff --git a/CPP_STYLE_GUIDE.md b/CPP_STYLE_GUIDE.md index 6266ee03b7c538..5a275094ad16fa 100644 --- a/CPP_STYLE_GUIDE.md +++ b/CPP_STYLE_GUIDE.md @@ -20,7 +20,8 @@ * [Others](#others) * [Type casting](#type-casting) * [Do not include `*.h` if `*-inl.h` has already been included](#do-not-include-h-if--inlh-has-already-been-included) - * [Avoid throwing JavaScript errors in nested C++ methods](#avoid-throwing-javascript-errors-in-nested-c-methods) + * [Avoid throwing JavaScript errors in C++ methods](#avoid-throwing-javascript-errors-in-c) + * [Avoid throwing JavaScript errors in nested C++ methods](#avoid-throwing-javascript-errors-in-nested-c-methods) Unfortunately, the C++ linter (based on [Google’s `cpplint`](https://github.com/google/styleguide)), which can be run @@ -213,12 +214,65 @@ instead of #include "util-inl.h" ``` -## Avoid throwing JavaScript errors in nested C++ methods +## Avoid throwing JavaScript errors in C++ -If you need to throw JavaScript errors from a C++ binding method, try to do it -at the top level and not inside of nested calls. +When there is a need to throw errors from a C++ binding method, try to +return the data necessary for constructing the errors to JavaScript, +then construct and throw the errors [using `lib/internal/errors.js`][errors]. -A lot of code inside Node.js is written so that typechecking etc. is performed -in JavaScript. +Note that in general, type-checks on arguments should be done in JavaScript +before the arguments are passed into C++.

Depending on +your operating system, there are also a number of other dependencies required. +These are detailed in the [Building guide][]. + +Once you have `git` and are sure you have all of the necessary dependencies, +it's time to create a fork. + +Before getting started, it is recommended to configure `git` so that it knows +who you are: + +```text +$ git config --global user.name "J. Random User" +$ git config --global user.email "j.random.user@example.com" +``` +Please make sure this local email is also added to your +[GitHub email list](https://github.com/settings/emails) so that your commits +will be properly associated with your account and you will be promoted +to Contributor once your first commit is landed. + +### Step 1: Fork + +Fork the project [on GitHub](https://github.com/nodejs/node) and clone your fork +locally. + +```text +$ git clone git@github.com:username/node.git +$ cd node +$ git remote add upstream https://github.com/nodejs/node.git +$ git fetch upstream +``` + +### Step 2: Branch + +As a best practice to keep your development environment as organized as +possible, create local branches to work within. These should also be created +directly off of the `master` branch. + +```text +$ git checkout -b my-branch -t upstream/master +``` + +## The Process of Making Changes + +### Step 3: Code + +The vast majority of Pull Requests opened against the `nodejs/node` +repository includes changes to either the C/C++ code contained in the `src` +directory, the JavaScript code contained in the `lib` directory, the +documentation in `docs/api` or tests within the `test` directory. + +If you are modifying code, please be sure to run `make lint` from time to +time to ensure that the changes follow the Node.js code style guide. + +Any documentation you write (including code comments and API documentation) +should follow the [Style Guide](doc/STYLE_GUIDE.md). Code samples included +in the API docs will also be checked when running `make lint` (or +`vcbuild.bat lint` on Windows). + +For contributing C++ code, you may want to look at the +[C++ Style Guide](CPP_STYLE_GUIDE.md). + +### Step 4: Commit + +It is a recommended best practice to keep your changes as logically grouped +as possible within individual commits. There is no limit to the number of +commits any single Pull Request may have, and many contributors find it easier +to review changes that are split across multiple commits. + +```text +$ git add my/changed/files +$ git commit +``` + +Note that multiple commits often get squashed when they are landed (see the +notes about [commit squashing](#commit-squashing)). + +#### Commit message guidelines + +A good commit message should describe what changed and why. + +1. The first line should: + - contain a short description of the change (preferably 50 characters or less, + and no more than 72 characters) + - be entirely in lowercase with the exception of proper nouns, acronyms, and + the words that refer to code, like function/variable names + - be prefixed with the name of the changed subsystem and start with an + imperative verb. Check the output of `git log --oneline files/you/changed` to + find out what subsystems your changes touch. + + Examples: + - `net: add localAddress and localPort to Socket` + - `src: fix typos in node_lttng_provider.h` + + +2. Keep the second line blank. +3. Wrap all other lines at 72 columns. + +4. If your patch fixes an open issue, you can add a reference to it at the end +of the log. Use the `Fixes:` prefix and the full issue URL.

If your commit introduces a breaking change (`semver-major`), it should +contain an explanation about the reason of the breaking change, which +situation would trigger the breaking change and what is the exact change. + +Breaking changes will be listed in the wiki with the aim to make upgrading +easier. Please have a look at [Breaking Changes](https://github.com/nodejs/node/wiki/Breaking-changes-between-v4-LTS-and-v6-LTS) +for the level of detail that's suitable. + +Sample complete commit message: + +```txt +subsystem: explain the commit in one line + +Body of commit message is a few lines of text, explaining things +in more detail, possibly giving some background about the issue +being fixed, etc. + +The body of the commit message can be several paragraphs, and +please do proper word-wrap and keep columns shorter than about +72 characters or so. That way, `git log` will show things +nicely even when it is indented. + +Fixes: https://github.com/nodejs/node/issues/1337 +Refs: http://eslint.org/docs/rules/space-in-parens.html +``` + +If you are new to contributing to Node.js, please try to do your best at +conforming to these guidelines, but do not worry if you get something wrong. +One of the existing contributors will help get things situated and the +contributor landing the Pull Request will ensure that everything follows +the project guidelines. + +See [core-validate-commit](https://github.com/evanlucas/core-validate-commit) - +A utility that ensures commits follow the commit formatting guidelines. + +### Step 5: Rebase + +As a best practice, once you have committed your changes, it is a good idea +to use `git rebase` (not `git merge`) to synchronize your work with the main +repository. + +```text +$ git fetch upstream +$ git rebase upstream/master +``` + +This ensures that your working branch has the latest changes from `nodejs/node` +master. + +### Step 6: Test + +Bug fixes and features should always come with tests. A +[guide for writing tests in Node.js][] has been +provided to make the process easier. Looking at other tests to see how they +should be structured can also help. + +The `test` directory within the `nodejs/node` repository is complex and it is +often not clear where a new test file should go. When in doubt, add new tests +to the `test/parallel/` directory and the right location will be sorted out +later. + +Before submitting your changes in a Pull Request, always run the full Node.js +test suite. To run the tests (including code linting) on Unix / macOS: + +```text +$ ./configure && make -j4 test +``` + +And on Windows: + +```text +> vcbuild test +``` + +(See the [Building guide][] for more details.) + +Make sure the linter does not report any issues and that all tests pass. Please +do not submit patches that fail either check. + +If you want to run the linter without running tests, use +`make lint`/`vcbuild lint`. It will run both JavaScript linting and +C++ linting. + +If you are updating tests and just want to run a single test to check it: + +```text +$ python tools/test.py -J --mode=release parallel/test-stream2-transform +``` + +You can execute the entire suite of tests for a given subsystem +by providing the name of a subsystem: + +```text +$ python tools/test.py -J --mode=release child-process +``` + +If you want to check the other options, please refer to the help by using +the `--help` option + +```text +$ python tools/test.py --help +``` + +You can usually run tests directly with node: + +```text +$ ./node ./test/parallel/test-stream2-transform.js +``` + +Remember to recompile with `make -j4` in between test runs if you change code in +the `lib` or `src` directories. + +#### Test Coverage + +It's good practice to ensure any code you add or change is covered by tests. +You can do so by running the test suite with coverage enabled: + +```text +$ ./configure --coverage && make coverage +``` + +A detailed coverage report will be written to `coverage/index.html` for +JavaScript coverage and to `coverage/cxxcoverage.html` for C++ coverage. + +_Note that generating a test coverage report can take several minutes._ + +To collect coverage for a subset of tests you can set the `CI_JS_SUITES` and +`CI_NATIVE_SUITES` variables: + +```text +$ CI_JS_SUITES=child-process CI_NATIVE_SUITES= make coverage +``` + +The above command executes tests for the `child-process` subsystem and +outputs the resulting coverage report. + +Running tests with coverage will create and modify several directories +and files. To clean up afterwards, run: + +```text +make coverage-clean +./configure && make -j4. +``` + +### Step 7: Push + +Once you are sure your commits are ready to go, with passing tests and linting, +begin the process of opening a Pull Request by pushing your working branch to +your fork on GitHub. + +```text +$ git push origin my-branch +``` + +### Step 8: Opening the Pull Request + +From within GitHub, opening a new Pull Request will present you with a template +that should be filled out: + +```markdown + + +#### Checklist + + +- [ ] `make -j4 test` (UNIX), or `vcbuild test` (Windows) passes +- [ ] tests and/or benchmarks are included +- [ ] documentation is changed or added +- [ ] commit message follows [commit guidelines](https://github.com/nodejs/node/blob/master/doc/guides/contributing/pull-requests.md#commit-message-guidelines) + +#### Affected core subsystem(s) + +``` + +Please try to do your best at filling out the details, but feel free to skip +parts if you're not sure what to put. + +Once opened, Pull Requests are usually reviewed within a few days. + +### Step 9: Discuss and update + +You will probably get feedback or requests for changes to your Pull Request. +This is a big part of the submission process so don't be discouraged! Some +contributors may sign off on the Pull Request right away, others may have +more detailed comments or feedback. This is a necessary part of the process +in order to evaluate whether the changes are correct and necessary. + +To make changes to an existing Pull Request, make the changes to your local +branch, add a new commit with those changes, and push those to your fork. +GitHub will automatically update the Pull Request. + +```text +$ git add my/changed/files +$ git commit +$ git push origin my-branch +``` + +It is also frequently necessary to synchronize your Pull Request with other +changes that have landed in `master` by using `git rebase`: + +```text +$ git fetch --all +$ git rebase origin/master +$ git push --force-with-lease origin my-branch +``` + +**Important:** The `git push --force-with-lease` command is one of the few ways +to delete history in `git`. Before you use it, make sure you understand the +risks. If in doubt, you can always ask for guidance in the Pull Request or on +[IRC in the #node-dev channel][]. + +If you happen to make a mistake in any of your commits, do not worry. You can +amend the last commit (for example if you want to change the commit log). + +```text +$ git add any/changed/files +$ git commit --amend +$ git push --force-with-lease origin my-branch +``` + +There are a number of more advanced mechanisms for managing commits using +`git rebase` that can be used, but are beyond the scope of this guide. + +Feel free to post a comment in the Pull Request to ping reviewers if you are +awaiting an answer on something. If you encounter words or acronyms that +seem unfamiliar, refer to this +[glossary](https://sites.google.com/a/chromium.org/dev/glossary). + +#### Approval and Request Changes Workflow + +All Pull Requests require "sign off" in order to land. Whenever a contributor +reviews a Pull Request they may find specific details that they would like to +see changed or fixed. These may be as simple as fixing a typo, or may involve +substantive changes to the code you have written. In general, such requests +are intended to be helpful, but at times may come across as abrupt or unhelpful, +especially requests to change things that do not include concrete suggestions +on *how* to change them. + +Try not to be discouraged. If you feel that a particular review is unfair, +say so, or contact one of the other contributors in the project and seek their +input. Often such comments are the result of the reviewer having only taken a +short amount of time to review and are not ill-intended. Such issues can often +be resolved with a bit of patience. That said, reviewers should be expected to +be helpful in their feedback, and feedback that is simply vague, dismissive and +unhelpful is likely safe to ignore. + +### Step 10: Landing + +In order to land, a Pull Request needs to be reviewed and [approved][] by +at least one Node.js Collaborator and pass a +[CI (Continuous Integration) test run][]. After that, as long as there are no +objections from other contributors, the Pull Request can be merged. If you find +your Pull Request waiting longer than you expect, see the +[notes about the waiting time](#waiting-until-the-pull-request-gets-landed). + +When a collaborator lands your Pull Request, they will post +a comment to the Pull Request page mentioning the commit(s) it +landed as. GitHub often shows the Pull Request as `Closed` at this +point, but don't worry. If you look at the branch you raised your +Pull Request against (probably `master`), you should see a commit with +your name on it. Congratulations and thanks for your contribution! + +## Reviewing Pull Requests + +All Node.js contributors who choose to review and provide feedback on Pull +Requests have a responsibility to both the project and the individual making the +contribution. Reviews and feedback must be helpful, insightful, and geared +towards improving the contribution as opposed to simply blocking it. If there +are reasons why you feel the PR should not land, explain what those are. Do not +expect to be able to block a Pull Request from advancing simply because you say +"No" without giving an explanation. Be open to having your mind changed. Be open +to working with the contributor to make the Pull Request better. + +Reviews that are dismissive or disrespectful of the contributor or any other +reviewers are strictly counter to the [Code of Conduct][]. + +When reviewing a Pull Request, the primary goals are for the codebase to improve +and for the person submitting the request to succeed. Even if a Pull Request +does not land, the submitters should come away from the experience feeling like +their effort was not wasted or unappreciated. Every Pull Request from a new +contributor is an opportunity to grow the community. + +### Review a bit at a time. + +Do not overwhelm new contributors. + +It is tempting to micro-optimize and make everything about relative performance, +perfect grammar, or exact style matches. Do not succumb to that temptation. + +Focus first on the most significant aspects of the change: + +1. Does this change make sense for Node.js? +2. Does this change make Node.js better, even if only incrementally? +3. Are there clear bugs or larger scale issues that need attending to? +4. Is the commit message readable and correct? If it contains a breaking change is it clear enough? + +When changes are necessary, *request* them, do not *demand* them, and do not +assume that the submitter already knows how to add a test or run a benchmark. + +Specific performance optimization techniques, coding styles and conventions +change over time. The first impression you give to a new contributor never does. + +Nits (requests for small changes that are not essential) are fine, but try to +avoid stalling the Pull Request. Most nits can typically be fixed by the +Node.js Collaborator landing the Pull Request but they can also be an +opportunity for the contributor to learn a bit more about the project. + +It is always good to clearly indicate nits when you comment: e.g. +`Nit: change foo() to bar(). But this is not blocking.` + +### Be aware of the person behind the code + +Be aware that *how* you communicate requests and reviews in your feedback can +have a significant impact on the success of the Pull Request. Yes, we may land +a particular change that makes Node.js better, but the individual might just +not want to have anything to do with Node.js ever again. The goal is not just +having good code. + +### Respect the minimum wait time for comments + +There is a minimum waiting time which we try to respect for non-trivial +changes, so that people who may have important input in such a distributed +project are able to respond. + +For non-trivial changes, Pull Requests must be left open for *at least* 48 +hours during the week, and 72 hours on a weekend. In most cases, when the +PR is relatively small and focused on a narrow set of changes, these periods +provide more than enough time to adequately review. Sometimes changes take far +longer to review, or need more specialized review from subject matter experts. +When in doubt, do not rush. + +Trivial changes, typically limited to small formatting changes or fixes to +documentation, may be landed within the minimum 48 hour window. + +### Abandoned or Stalled Pull Requests + +If a Pull Request appears to be abandoned or stalled, it is polite to first +check with the contributor to see if they intend to continue the work before +checking if they would mind if you took it over (especially if it just has +nits left). When doing so, it is courteous to give the original contributor +credit for the work they started (either by preserving their name and email +address in the commit log, or by using an `Author: ` meta-data tag in the +commit. + +### Approving a change + +Any Node.js core Collaborator (any GitHub user with commit rights in the +`nodejs/node` repository) is authorized to approve any other contributor's +work. Collaborators are not permitted to approve their own Pull Requests. + +Collaborators indicate that they have reviewed and approve of the changes in +a Pull Request either by using GitHub's Approval Workflow, which is preferred, +or by leaving an `LGTM` ("Looks Good To Me") comment. + +When explicitly using the "Changes requested" component of the GitHub Approval +Workflow, show empathy. That is, do not be rude or abrupt with your feedback +and offer concrete suggestions for improvement, if possible. If you're not +sure *how* a particular change can be improved, say so. + +Most importantly, after leaving such requests, it is courteous to make yourself +available later to check whether your comments have been addressed. + +If you see that requested changes have been made, you can clear another +collaborator's `Changes requested` review. + +Change requests that are vague, dismissive, or unconstructive may also be +dismissed if requests for greater clarification go unanswered within a +reasonable period of time. + +If you do not believe that the Pull Request should land at all, use +`Changes requested` to indicate that you are considering some of your comments +to block the PR from landing. When doing so, explain *why* you believe the +Pull Request should not land along with an explanation of what may be an +acceptable alternative course, if any. + +### Accept that there are different opinions about what belongs in Node.js + +Opinions on this vary, even among the members of the Technical Steering +Committee. + +One general rule of thumb is that if Node.js itself needs it (due to historic +or functional reasons), then it belongs in Node.js. For instance, `url` +parsing is in Node.js because of HTTP protocol support. + +Also, functionality that either cannot be implemented outside of core in any +reasonable way, or only with significant pain. + +It is not uncommon for contributors to suggest new features they feel would +make Node.js better. These may or may not make sense to add, but as with all +changes, be courteous in how you communicate your stance on these. Comments +that make the contributor feel like they should have "known better" or +ridiculed for even trying run counter to the [Code of Conduct][]. + +### Performance is not everything + +Node.js has always optimized for speed of execution. If a particular change +can be shown to make some part of Node.js faster, it's quite likely to be +accepted. Claims that a particular Pull Request will make things faster will +almost always be met by requests for performance [benchmark results][] that +demonstrate the improvement. + +That said, performance is not the only factor to consider. Node.js also +optimizes in favor of not breaking existing code in the ecosystem, and not +changing working functional code just for the sake of changing. + +If a particular Pull Request introduces a performance or functional +regression, rather than simply rejecting the Pull Request, take the time to +work *with* the contributor on improving the change. Offer feedback and +advice on what would make the Pull Request acceptable, and do not assume that +the contributor should already know how to do that. Be explicit in your +feedback. + +### Continuous Integration Testing + +All Pull Requests that contain changes to code must be run through +continuous integration (CI) testing at [https://ci.nodejs.org/][]. + +Only Node.js core Collaborators with commit rights to the `nodejs/node` +repository may start a CI testing run. The specific details of how to do +this are included in the new Collaborator [Onboarding guide][]. + +Ideally, the code change will pass ("be green") on all platform configurations +supported by Node.js (there are over 30 platform configurations currently). +This means that all tests pass and there are no linting errors. In reality, +however, it is not uncommon for the CI infrastructure itself to fail on +specific platforms or for so-called "flaky" tests to fail ("be red"). It is +vital to visually inspect the results of all failed ("red") tests to determine +whether the failure was caused by the changes in the Pull Request. + +## Additional Notes + +### Commit Squashing + +When the commits in your Pull Request land, they may be squashed +into one commit per logical change. Metadata will be added to the commit +message (including links to the Pull Request, links to relevant issues, +and the names of the reviewers). The commit history of your Pull Request, +however, will stay intact on the Pull Request page. + +For the size of "one logical change", +[0b5191f](https://github.com/nodejs/node/commit/0b5191f15d0f311c804d542b67e2e922d98834f8) +can be a good example. It touches the implementation, the documentation, +and the tests, but is still one logical change. In general, the tests should +always pass when each individual commit lands on the master branch. + +### Getting Approvals for Your Pull Request + +A Pull Request is approved either by saying LGTM, which stands for +"Looks Good To Me", or by using GitHub's Approve button. +GitHub's Pull Request review feature can be used during the process. +For more information, check out +[the video tutorial](https://www.youtube.com/watch?v=HW0RPaJqm4g) +or [the official documentation](https://help.github.com/articles/reviewing-changes-in-pull-requests/). + +After you push new changes to your branch, you need to get +approval for these new changes again, even if GitHub shows "Approved" +because the reviewers have hit the buttons before. + +### CI Testing + +Every Pull Request needs to be tested +to make sure that it works on the platforms that Node.js +supports. This is done by running the code through the CI system. + +Only a Collaborator can start a CI run. Usually one of them will do it +for you as approvals for the Pull Request come in. +If not, you can ask a Collaborator to start a CI run. + +### Waiting Until the Pull Request Gets Landed + +A Pull Request needs to stay open for at least 48 hours (72 hours on a +weekend) from when it is submitted, even after it gets approved and +passes the CI. This is to make sure that everyone has a chance to +weigh in. If the changes are trivial, collaborators may decide it +doesn't need to wait. A Pull Request may well take longer to be +merged in. All these precautions are important because Node.js is +widely used, so don't be discouraged! + +### Check Out the Collaborator's Guide + +If you want to know more about the code review and the landing process, +you can take a look at the +[collaborator's guide](https://github.com/nodejs/node/blob/master/COLLABORATOR_GUIDE.md). + +[approved]: #getting-approvals-for-your-pull-request +[benchmark results]: ../writing-and-running-benchmarks.md +[Building guide]: ../../../BUILDING.md +[CI (Continuous Integration) test run]: #ci-testing +[Code of Conduct]: https://github.com/nodejs/admin/blob/master/CODE_OF_CONDUCT.md +[guide for writing tests in Node.js]: ../writing-tests.md +[https://ci.nodejs.org/]: https://ci.nodejs.org/ +[IRC in the #node-dev channel]: https://webchat.freenode.net?channels=node-dev&uio=d4 +[Onboarding guide]: ../onboarding.md diff --git a/doc/guides/maintaining-V8.md b/doc/guides/maintaining-V8.md index d45fa072074aee..04bc155660105b 100644 --- a/doc/guides/maintaining-V8.md +++ b/doc/guides/maintaining-V8.md @@ -29,8 +29,7 @@ For example, at the time of this writing: released as part of the Chromium **canary** builds.

However, due to the nature of ESLint as a code quality tool, it's not always clear when a minor or major version bump occurs. To help clarify this for everyone, we've defined the following semantic versioning policy for ESLint: - -* Patch release (intended to not break your lint build) - * A bug fix in a rule that results in ESLint reporting fewer errors. - * A bug fix to the CLI or core (including formatters). - * Improvements to documentation. - * Non-user-facing changes such as refactoring code, adding, deleting, or modifying tests, and increasing test coverage. - * Re-releasing after a failed release (i.e., publishing a release that doesn't work for anyone). -* Minor release (might break your lint build) - * A bug fix in a rule that results in ESLint reporting more errors. - * A new rule is created. - * A new option to an existing rule that does not result in ESLint reporting more errors by default. - * An existing rule is deprecated. - * A new CLI capability is created. - * New capabilities to the public API are added (new classes, new methods, new arguments to existing methods, etc.). - * A new formatter is created. -* Major release (likely to break your lint build) - * `eslint:recommended` is updated. - * A new option to an existing rule that results in ESLint reporting more errors by default. - * An existing formatter is removed. - * Part of the public API is removed or changed in an incompatible way. - -According to our policy, any minor update may report more errors than the previous release (ex: from a bug fix). As such, we recommend using the tilde (`~`) in `package.json` e.g. `"eslint": "~3.1.0"` to guarantee the results of your builds. - -## License - -[![FOSSA Status](https://app.fossa.io/api/projects/git%2Bhttps%3A%2F%2Fgithub.com%2Feslint%2Feslint.svg?type=large)](https://app.fossa.io/projects/git%2Bhttps%3A%2F%2Fgithub.com%2Feslint%2Feslint?ref=badge_large) - -## Frequently Asked Questions - -### How is ESLint different from JSHint? - -The most significant difference is that ESlint has pluggable linting rules. That means you can use the rules it comes with, or you can extend it with rules created by others or by yourself! - -### How does ESLint performance compare to JSHint? - -ESLint is slower than JSHint, usually 2-3x slower on a single file. This is because ESLint uses Espree to construct an AST before it can evaluate your code whereas JSHint evaluates your code as it's being parsed. The speed is also based on the number of rules you enable; the more rules you enable, the slower the process. - -Despite being slower, we believe that ESLint is fast enough to replace JSHint without causing significant pain. - -### I heard ESLint is going to replace JSCS? - -Yes. Since we are solving the same problems, ESLint and JSCS teams have decided to join forces and work together in the development of ESLint instead of competing with each other. You can read more about this in both [ESLint](https://eslint.org/blog/2016/04/welcoming-jscs-to-eslint) and [JSCS](https://medium.com/@markelog/jscs-end-of-the-line-bc9bf0b3fdb2#.u76sx334n) announcements. - -### So, should I stop using JSCS and start using ESLint? - -Maybe, depending on how much you need it. [JSCS has reached end of life](https://eslint.org/blog/2016/07/jscs-end-of-life), but if it is working for you then there is no reason to move yet. We are still working to smooth the transition. You can see our progress [here](https://github.com/eslint/eslint/milestones/JSCS%20Compatibility). We’ll announce when all of the changes necessary to support JSCS users in ESLint are complete and will start encouraging JSCS users to switch to ESLint at that time. - -If you are having issues with JSCS, you can try to move to ESLint. We are focusing our time and energy on JSCS compatibility issues. - -### Is ESLint just linting or does it also check style? - -ESLint does both traditional linting (looking for problematic patterns) and style checking (enforcement of conventions). You can use it for both. - -### Why can't ESLint find my plugins? - -ESLint can be [globally or locally installed](#installation-and-usage). If you install ESLint globally, your plugins must also be installed globally; if you install ESLint locally, your plugins must also be installed locally. - -If you are trying to run globally, make sure your plugins are installed globally (use `npm ls -g`). - -If you are trying to run locally: - -* Make sure your plugins (and ESLint) are both in your project's `package.json` as devDependencies (or dependencies, if your project uses ESLint at runtime). -* Make sure you have run `npm install` and all your dependencies are installed. - -In all cases, make sure your plugins' peerDependencies have been installed as well. You can use `npm view eslint-plugin-myplugin peerDepencies` to see what peer dependencies `eslint-plugin-myplugin` has. - -### Does ESLint support JSX? - -Yes, ESLint natively supports parsing JSX syntax (this must be enabled in [configuration](https://eslint.org/docs/user-guide/configuring)). Please note that supporting JSX syntax *is not* the same as supporting React. React applies specific semantics to JSX syntax that ESLint doesn't recognize. We recommend using [eslint-plugin-react](https://www.npmjs.com/package/eslint-plugin-react) if you are using React and want React semantics. - -### What about ECMAScript 6 support? - -ESLint has full support for ECMAScript 6. By default, this support is off. You can enable ECMAScript 6 syntax and global variables through [configuration](https://eslint.org/docs/user-guide/configuring). - -### What about experimental features? - -ESLint doesn't natively support experimental ECMAScript language features. You can use [babel-eslint](https://github.com/babel/babel-eslint) to use any option available in Babel. - -Once a language feature has been adopted into the ECMAScript standard (stage 4 according to the [TC39 process](https://tc39.github.io/process-document/)), we will accept issues and pull requests related to the new feature, subject to our [contributing guidelines](https://eslint.org/docs/developer-guide/contributing). Until then, please use the appropriate parser and plugin(s) for your experimental feature. - -### Where to ask for help? - -Join our [Mailing List](https://groups.google.com/group/eslint) or [Chatroom](https://gitter.im/eslint/eslint) - - -[npm-image]: https://img.shields.io/npm/v/eslint.svg?style=flat-square -[npm-url]: https://www.npmjs.com/package/eslint -[travis-image]: https://img.shields.io/travis/eslint/eslint/master.svg?style=flat-square -[travis-url]: https://travis-ci.org/eslint/eslint -[appveyor-image]: https://ci.appveyor.com/api/projects/status/iwxmiobcvbw3b0av/branch/master?svg=true -[appveyor-url]: https://ci.appveyor.com/project/nzakas/eslint/branch/master -[coveralls-image]: https://img.shields.io/coveralls/eslint/eslint/master.svg?style=flat-square -[coveralls-url]: https://coveralls.io/r/eslint/eslint?branch=master -[downloads-image]: https://img.shields.io/npm/dm/eslint.svg?style=flat-square -[downloads-url]: https://www.npmjs.com/package/eslint diff --git a/tools/eslint/lib/options.js b/tools/eslint/lib/options.js deleted file mode 100644 index ee1d3369cecf36..00000000000000 --- a/tools/eslint/lib/options.js +++ /dev/null @@ -1,235 +0,0 @@ -/** - * @fileoverview Options configuration for optionator. - * @author George Zahariev - */ - -"use strict"; - -//------------------------------------------------------------------------------ -// Requirements -//------------------------------------------------------------------------------ - -const optionator = require("optionator"); - -//------------------------------------------------------------------------------ -// Initialization and Public Interface -//------------------------------------------------------------------------------ - -// exports "parse(args)", "generateHelp()", and "generateHelpForOption(optionName)" -module.exports = optionator({ - prepend: "eslint [options] file.js [file.js] [dir]", - defaults: { - concatRepeatedArrays: true, - mergeRepeatedObjects: true - }, - options: [ - { - heading: "Basic configuration" - }, - { - option: "config", - alias: "c", - type: "path::String", - description: "Use configuration from this file or shareable config" - }, - { - option: "eslintrc", - type: "Boolean", - default: "true", - description: "Disable use of configuration from .eslintrc" - }, - { - option: "env", - type: "[String]", - description: "Specify environments" - }, - { - option: "ext", - type: "[String]", - default: ".js", - description: "Specify JavaScript file extensions" - }, - { - option: "global", - type: "[String]", - description: "Define global variables" - }, - { - option: "parser", - type: "String", - description: "Specify the parser to be used" - }, - { - option: "parser-options", - type: "Object", - description: "Specify parser options" - }, - { - heading: "Caching" - }, - { - option: "cache", - type: "Boolean", - default: "false", - description: "Only check changed files" - }, - { - option: "cache-file", - type: "path::String", - default: ".eslintcache", - description: "Path to the cache file.

Set this to `true` to accept such - code. - -- **allowImportExportEverywhere**: By default, `import` and `export` - declarations can only appear at a program's top level. Setting this - option to `true` allows them anywhere where a statement is allowed. - -- **allowHashBang**: When this is enabled (off by default), if the - code starts with the characters `#!` (as in a shellscript), the - first line will be treated as a comment. - -- **locations**: When `true`, each node has a `loc` object attached - with `start` and `end` subobjects, each of which contains the - one-based line and zero-based column numbers in `{line, column}` - form. Default is `false`. - -- **onToken**: If a function is passed for this option, each found - token will be passed in same format as tokens returned from - `tokenizer().getToken()`. - - If array is passed, each found token is pushed to it. - - Note that you are not allowed to call the parser from the - callback—that will corrupt its internal state. - -- **onComment**: If a function is passed for this option, whenever a - comment is encountered the function will be called with the - following parameters: - - - `block`: `true` if the comment is a block comment, false if it - is a line comment. - - `text`: The content of the comment. - - `start`: Character offset of the start of the comment. - - `end`: Character offset of the end of the comment. - - When the `locations` options is on, the `{line, column}` locations - of the comment’s start and end are passed as two additional - parameters. - - If array is passed for this option, each found comment is pushed - to it as object in Esprima format: - - ```javascript - { - "type": "Line" | "Block", - "value": "comment text", - "start": Number, - "end": Number, - // If `locations` option is on: - "loc": { - "start": {line: Number, column: Number} - "end": {line: Number, column: Number} - }, - // If `ranges` option is on: - "range": [Number, Number] - } - ``` - - Note that you are not allowed to call the parser from the - callback—that will corrupt its internal state. - -- **ranges**: Nodes have their start and end characters offsets - recorded in `start` and `end` properties (directly on the node, - rather than the `loc` object, which holds line/column data. To also - add a [semi-standardized][range] `range` property holding a - `[start, end]` array with the same numbers, set the `ranges` option - to `true`. - -- **program**: It is possible to parse multiple files into a single - AST by passing the tree produced by parsing the first file as the - `program` option in subsequent parses. This will add the toplevel - forms of the parsed file to the "Program" (top) node of an existing - parse tree. - -- **sourceFile**: When the `locations` option is `true`, you can pass - this option to add a `source` attribute in every node’s `loc` - object. Note that the contents of this option are not examined or - processed in any way; you are free to use whatever format you - choose. - -- **directSourceFile**: Like `sourceFile`, but a `sourceFile` property - will be added (regardless of the `location` option) directly to the - nodes, rather than the `loc` object. - -- **preserveParens**: If this option is `true`, parenthesized expressions - are represented by (non-standard) `ParenthesizedExpression` nodes - that have a single `expression` property containing the expression - inside parentheses. - -[range]: https://bugzilla.mozilla.org/show_bug.cgi?id=745678 - -**parseExpressionAt**`(input, offset, options)` will parse a single -expression in a string, and return its AST. It will not complain if -there is more of the string left after the expression. - -**getLineInfo**`(input, offset)` can be used to get a `{line, -column}` object for a given program string and character offset. - -**tokenizer**`(input, options)` returns an object with a `getToken` -method that can be called repeatedly to get the next token, a `{start, -end, type, value}` object (with added `loc` property when the -`locations` option is enabled and `range` property when the `ranges` -option is enabled). When the token's type is `tokTypes.eof`, you -should stop calling the method, since it will keep returning that same -token forever. - -In ES6 environment, returned result can be used as any other -protocol-compliant iterable: - -```javascript -for (let token of acorn.tokenizer(str)) { - // iterate over the tokens -} - -// transform code to array of tokens: -var tokens = [...acorn.tokenizer(str)]; -``` - -**tokTypes** holds an object mapping names to the token type objects -that end up in the `type` properties of tokens. - -#### Note on using with [Escodegen][escodegen] - -Escodegen supports generating comments from AST, attached in -Esprima-specific format. In order to simulate same format in -Acorn, consider following example: - -```javascript -var comments = [], tokens = []; - -var ast = acorn.parse('var x = 42; // answer', { - // collect ranges for each node - ranges: true, - // collect comments in Esprima's format - onComment: comments, - // collect token ranges - onToken: tokens -}); - -// attach comments using collected information -escodegen.attachComments(ast, comments, tokens); - -// generate code -console.log(escodegen.generate(ast, {comment: true})); -// > 'var x = 42; // answer' -``` - -[escodegen]: https://github.com/estools/escodegen - -### dist/acorn_loose.js ### - -This file implements an error-tolerant parser. It exposes a single -function. The loose parser is accessible in node.js via `require("acorn/dist/acorn_loose")`. - -**parse_dammit**`(input, options)` takes the same arguments and -returns the same syntax tree as the `parse` function in `acorn.js`, -but never raises an error, and will do its best to parse syntactically -invalid code in as meaningful a way as it can. It'll insert identifier -nodes with name `"✖"` as placeholders in places where it can't make -sense of the input. Depends on `acorn.js`, because it uses the same -tokenizer. - -### dist/walk.js ### - -Implements an abstract syntax tree walker. Will store its interface in -`acorn.walk` when loaded without a module system. - -**simple**`(node, visitors, base, state)` does a 'simple' walk over -a tree. `node` should be the AST node to walk, and `visitors` an -object with properties whose names correspond to node types in the -[ESTree spec][estree]. The properties should contain functions -that will be called with the node object and, if applicable the state -at that point. The last two arguments are optional. `base` is a walker -algorithm, and `state` is a start state. The default walker will -simply visit all statements and expressions and not produce a -meaningful state. (An example of a use of state is to track scope at -each point in the tree.) - -```js -const acorn = require("acorn") -const walk = require("acorn/dist/walk") - -walk.simple(acorn.parse("let x = 10"), { - Literal(node) { - console.log(`Found a literal: ${node.value}`) - } -}) -``` - -**ancestor**`(node, visitors, base, state)` does a 'simple' walk over -a tree, building up an array of ancestor nodes (including the current node) -and passing the array to the callbacks as a third parameter. - -```js -const acorn = require("acorn") -const walk = require("acorn/dist/walk") - -walk.ancestor(acorn.parse("foo('hi')"), { - Literal(_, ancestors) { - console.log("This literal's ancestors are:", - ancestors.map(n => n.type)) - } -}) -``` - -**recursive**`(node, state, functions, base)` does a 'recursive' -walk, where the walker functions are responsible for continuing the -walk on the child nodes of their target node. `state` is the start -state, and `functions` should contain an object that maps node types -to walker functions. Such functions are called with `(node, state, c)` -arguments, and can cause the walk to continue on a sub-node by calling -the `c` argument on it with `(node, state)` arguments. The optional -`base` argument provides the fallback walker functions for node types -that aren't handled in the `functions` object. If not given, the -default walkers will be used. - -**make**`(functions, base)` builds a new walker object by using the -walker functions in `functions` and filling in the missing ones by -taking defaults from `base`. - -**full**`(node, callback, base, state)` does a 'full' -walk over a tree, calling the callback with the arguments (node, state, type) -for each node - -**fullAncestor**`(node, callback, base, state)` does a 'full' walk over -a tree, building up an array of ancestor nodes (including the current node) -and passing the array to the callbacks as a third parameter. - -```js -const acorn = require("acorn") -const walk = require("acorn/dist/walk") - -walk.full(acorn.parse("1 + 1"), node => { - console.log(`There's a ${node.type} node at ${node.ch}`) -}) -``` - -**findNodeAt**`(node, start, end, test, base, state)` tries to -locate a node in a tree at the given start and/or end offsets, which -satisfies the predicate `test`. `start` and `end` can be either `null` -(as wildcard) or a number. `test` may be a string (indicating a node -type) or a function that takes `(nodeType, node)` arguments and -returns a boolean indicating whether this node is interesting. `base` -and `state` are optional, and can be used to specify a custom walker. -Nodes are tested from inner to outer, so if two nodes match the -boundaries, the inner one will be preferred. - -**findNodeAround**`(node, pos, test, base, state)` is a lot like -`findNodeAt`, but will match any node that exists 'around' (spanning) -the given position. - -**findNodeAfter**`(node, pos, test, base, state)` is similar to -`findNodeAround`, but will match all nodes *after* the given position -(testing outer nodes before inner nodes). - -## Command line interface - -The `bin/acorn` utility can be used to parse a file from the command -line. It accepts as arguments its input file and the following -options: - -- `--ecma3|--ecma5|--ecma6|--ecma7|--ecma8|--ecma9`: Sets the ECMAScript version - to parse. Default is version 7. - -- `--module`: Sets the parsing mode to `"module"`. Is set to `"script"` otherwise. - -- `--locations`: Attaches a "loc" object to each node with "start" and - "end" subobjects, each of which contains the one-based line and - zero-based column numbers in `{line, column}` form. - -- `--allow-hash-bang`: If the code starts with the characters #! (as in a shellscript), the first line will be treated as a comment. - -- `--compact`: No whitespace is used in the AST output. - -- `--silent`: Do not output the AST, just return the exit status. - -- `--help`: Print the usage information and quit. - -The utility spits out the syntax tree as JSON data. - -## Build system - -Acorn is written in ECMAScript 6, as a set of small modules, in the -project's `src` directory, and compiled down to bigger ECMAScript 3 -files in `dist` using [Browserify](http://browserify.org) and -[Babel](http://babeljs.io/). If you are already using Babel, you can -consider including the modules directly. - -The command-line test runner (`npm test`) uses the ES6 modules. The -browser-based test page (`test/index.html`) uses the compiled modules. -The `bin/build-acorn.js` script builds the latter from the former. - -If you are working on Acorn, you'll probably want to try the code out -directly, without an intermediate build step. In your scripts, you can -register the Babel require shim like this: - - require("babel-core/register") - -That will allow you to directly `require` the ES6 modules. - -## Plugins - -Acorn is designed support allow plugins which, within reasonable -bounds, redefine the way the parser works. Plugins can add new token -types and new tokenizer contexts (if necessary), and extend methods in -the parser object. This is not a clean, elegant API—using it requires -an understanding of Acorn's internals, and plugins are likely to break -whenever those internals are significantly changed. But still, it is -_possible_, in this way, to create parsers for JavaScript dialects -without forking all of Acorn. And in principle it is even possible to -combine such plugins, so that if you have, for example, a plugin for -parsing types and a plugin for parsing JSX-style XML literals, you -could load them both and parse code with both JSX tags and types. - -A plugin should register itself by adding a property to -`acorn.plugins`, which holds a function. Calling `acorn.parse`, a -`plugins` option can be passed, holding an object mapping plugin names -to configuration values (or just `true` for plugins that don't take -options). After the parser object has been created, the initialization -functions for the chosen plugins are called with `(parser, -configValue)` arguments. They are expected to use the `parser.extend` -method to extend parser methods. For example, the `readToken` method -could be extended like this: - -```javascript -parser.extend("readToken", function(nextMethod) { - return function(code) { - console.log("Reading a token!") - return nextMethod.call(this, code) - } -}) -``` - -The `nextMethod` argument passed to `extend`'s second argument is the -previous value of this method, and should usually be called through to -whenever the extended method does not handle the call itself. - -Similarly, the loose parser allows plugins to register themselves via -`acorn.pluginsLoose`. The extension mechanism is the same as for the -normal parser: - -```javascript -looseParser.extend("readToken", function(nextMethod) { - return function() { - console.log("Reading a token in the loose parser!") - return nextMethod.call(this) - } -}) -``` - -### Existing plugins - - - [`acorn-jsx`](https://github.com/RReverser/acorn-jsx): Parse [Facebook JSX syntax extensions](https://github.com/facebook/jsx) - - [`acorn-es7-plugin`](https://github.com/MatAtBread/acorn-es7-plugin/): Parse [async/await syntax proposal](https://github.com/tc39/ecmascript-asyncawait) - - [`acorn-object-spread`](https://github.com/UXtemple/acorn-object-spread): Parse [object spread syntax proposal](https://github.com/sebmarkbage/ecmascript-rest-spread) - - [`acorn-es7`](https://www.npmjs.com/package/acorn-es7): Parse [decorator syntax proposal](https://github.com/wycats/javascript-decorators) - - [`acorn-objj`](https://www.npmjs.com/package/acorn-objj): [Objective-J](http://www.cappuccino-project.org/learn/objective-j.html) language parser built as Acorn plugin - - [`acorn-object-rest-spread`](https://github.com/victor-homyakov/acorn-object-rest-spread) Parse [Object Rest/Spread Properties proposal](https://github.com/tc39/proposal-object-rest-spread), works with latest Acorn version (5.0.3) - - [`acorn-static-class-property-initializer`](https://github.com/victor-homyakov/acorn-static-class-property-initializer) Partial support for static class properties from [ES Class Fields & Static Properties Proposal](https://github.com/tc39/proposal-class-public-fields) to support static property initializers in [React components written as ES6+ classes](https://babeljs.io/blog/2015/06/07/react-on-es6-plus) - diff --git a/tools/eslint/node_modules/acorn/package.json b/tools/eslint/node_modules/acorn/package.json deleted file mode 100644 index 610943538459dd..00000000000000 --- a/tools/eslint/node_modules/acorn/package.json +++ /dev/null @@ -1,286 +0,0 @@ -{ - "_from": "acorn@^5.2.1", - "_id": "acorn@5.2.1", - "_inBundle": false, - "_integrity": "sha512-jG0u7c4Ly+3QkkW18V+NRDN+4bWHdln30NL1ZL2AvFZZmQe/BfopYCtghCKKVBUSetZ4QKcyA0pY6/4Gw8Pv8w==", - "_location": "/eslint/acorn", - "_phantomChildren": {}, - "_requested": { - "type": "range", - "registry": true, - "raw": "acorn@^5.2.1", - "name": "acorn", - "escapedName": "acorn", - "rawSpec": "^5.2.1", - "saveSpec": null, - "fetchSpec": "^5.2.1" - }, - "_requiredBy": [ - "/eslint/espree" - ], - "_resolved": "https://registry.npmjs.org/acorn/-/acorn-5.2.1.tgz", - "_shasum": "317ac7821826c22c702d66189ab8359675f135d7", - "_spec": "acorn@^5.2.1", - "_where": "/Users/cjihrig/iojs/node/tools/eslint-tmp/node_modules/eslint/node_modules/espree", - "bin": { - "acorn": "./bin/acorn" - }, - "bugs": { - "url": "https://github.com/ternjs/acorn/issues" - }, - "bundleDependencies": false, - "contributors": [ - { - "name": "List of Acorn contributors.

-Currently Ajv is the fastest and the most standard compliant validator according to these benchmarks: - -- [json-schema-benchmark](https://github.com/ebdrup/json-schema-benchmark) - 50% faster than the second place -- [jsck benchmark](https://github.com/pandastrike/jsck#benchmarks) - 20-190% faster -- [z-schema benchmark](https://rawgit.com/zaggino/z-schema/master/benchmark/results.html) -- [themis benchmark](https://cdn.rawgit.com/playlyfe/themis/master/benchmark/results.html) -

- -## Features - -- Ajv implements full JSON Schema [draft 6](http://json-schema.org/) and draft 4 standards: - - all validation keywords (see [JSON Schema validation keywords](https://github.com/epoberezkin/ajv/blob/master/KEYWORDS.md)) - - full support of remote refs (remote schemas have to be added with `addSchema` or compiled to be available) - - support of circular references between schemas - - correct string lengths for strings with unicode pairs (can be turned off) - - [formats](#formats) defined by JSON Schema draft 4 standard and custom formats (can be turned off) - - [validates schemas against meta-schema](#api-validateschema) -- supports [browsers](#using-in-browser) and Node.js 0.10-8.x -- [asynchronous loading](#asynchronous-schema-compilation) of referenced schemas during compilation -- "All errors" validation mode with [option allErrors](#options) -- [error messages with parameters](#validation-errors) describing error reasons to allow creating custom error messages -- i18n error messages support with [ajv-i18n](https://github.com/epoberezkin/ajv-i18n) package -- [filtering data](#filtering-data) from additional properties -- [assigning defaults](#assigning-defaults) to missing properties and items -- [coercing data](#coercing-data-types) to the types specified in `type` keywords -- [custom keywords](#defining-custom-keywords) -- draft-6 keywords `const`, `contains` and `propertyNames` -- draft-6 boolean schemas (`true`/`false` as a schema to always pass/fail). -- keywords `switch`, `patternRequired`, `formatMaximum` / `formatMinimum` and `formatExclusiveMaximum` / `formatExclusiveMinimum` from [JSON-schema extension proposals](https://github.com/json-schema/json-schema/wiki/v5-Proposals) with [ajv-keywords](https://github.com/epoberezkin/ajv-keywords) package -- [$data reference](#data-reference) to use values from the validated data as values for the schema keywords -- [asynchronous validation](#asynchronous-validation) of custom formats and keywords - -Currently Ajv is the only validator that passes all the tests from [JSON Schema Test Suite](https://github.com/json-schema/JSON-Schema-Test-Suite) (according to [json-schema-benchmark](https://github.com/ebdrup/json-schema-benchmark), apart from the test that requires that `1.0` is not an integer that is impossible to satisfy in JavaScript). - - -## Install - -``` -npm install ajv -``` - -or to install [version 6](https://github.com/epoberezkin/ajv/tree/beta): - -``` -npm install ajv@beta -``` - - -## Getting started - -Try it in the Node.js REPL: https://tonicdev.com/npm/ajv - - -The fastest validation call: - -```javascript -var Ajv = require('ajv'); -var ajv = new Ajv(); // options can be passed, e.g. {allErrors: true} -var validate = ajv.compile(schema); -var valid = validate(data); -if (!valid) console.log(validate.errors); -``` - -or with less code - -```javascript -// ... -var valid = ajv.validate(schema, data); -if (!valid) console.log(ajv.errors); -// ... -``` - -or - -```javascript -// ... -var valid = ajv.addSchema(schema, 'mySchema') - .validate('mySchema', data); -if (!valid) console.log(ajv.errorsText()); -// ... -``` - -See [API](#api) and [Options](#options) for more details. - -Ajv compiles schemas to functions and caches them in all cases (using schema serialized with [fast-json-stable-stringify](https://github.com/epoberezkin/fast-json-stable-stringify) or a custom function as a key), so that the next time the same schema is used (not necessarily the same object instance) it won't be compiled again. - -The best performance is achieved when using compiled functions returned by `compile` or `getSchema` methods (there is no additional function call). - -__Please note__: every time a validation function or `ajv.validate` are called `errors` property is overwritten. You need to copy `errors` array reference to another variable if you want to use it later (e.g., in the callback). See [Validation errors](#validation-errors) - - -## Using in browser - -You can require Ajv directly from the code you browserify - in this case Ajv will be a part of your bundle. - -If you need to use Ajv in several bundles you can create a separate UMD bundle using `npm run bundle` script (thanks to [siddo420](https://github.com/siddo420)). - -Then you need to load Ajv in the browser: -```html - -``` - -This bundle can be used with different module systems; it creates global `Ajv` if no module system is found. - -The browser bundle is available on [cdnjs](https://cdnjs.com/libraries/ajv). - -Ajv is tested with these browsers: - -[![Sauce Test Status](https://saucelabs.com/browser-matrix/epoberezkin.svg)](https://saucelabs.com/u/epoberezkin) - -__Please note__: some frameworks, e.g. Dojo, may redefine global require in such way that is not compatible with CommonJS module format. In such case Ajv bundle has to be loaded before the framework and then you can use global Ajv (see issue [#234](https://github.com/epoberezkin/ajv/issues/234)). - - -## Command line interface - -CLI is available as a separate npm package [ajv-cli](https://github.com/jessedc/ajv-cli). It supports: - -- compiling JSON-schemas to test their validity -- BETA: generating standalone module exporting a validation function to be used without Ajv (using [ajv-pack](https://github.com/epoberezkin/ajv-pack)) -- migrate schemas to draft-06 (using [json-schema-migrate](https://github.com/epoberezkin/json-schema-migrate)) -- validating data file(s) against JSON-schema -- testing expected validity of data against JSON-schema -- referenced schemas -- custom meta-schemas -- files in JSON and JavaScript format -- all Ajv options -- reporting changes in data after validation in [JSON-patch](https://tools.ietf.org/html/rfc6902) format - - -## Validation keywords - -Ajv supports all validation keywords from draft 4 of JSON-schema standard: - -- [type](https://github.com/epoberezkin/ajv/blob/master/KEYWORDS.md#type) -- [for numbers](https://github.com/epoberezkin/ajv/blob/master/KEYWORDS.md#keywords-for-numbers) - maximum, minimum, exclusiveMaximum, exclusiveMinimum, multipleOf -- [for strings](https://github.com/epoberezkin/ajv/blob/master/KEYWORDS.md#keywords-for-strings) - maxLength, minLength, pattern, format -- [for arrays](https://github.com/epoberezkin/ajv/blob/master/KEYWORDS.md#keywords-for-arrays) - maxItems, minItems, uniqueItems, items, additionalItems, [contains](https://github.com/epoberezkin/ajv/blob/master/KEYWORDS.md#contains) -- [for objects](https://github.com/epoberezkin/ajv/blob/master/KEYWORDS.md#keywords-for-objects) - maxProperties, minProperties, required, properties, patternProperties, additionalProperties, dependencies, [propertyNames](https://github.com/epoberezkin/ajv/blob/master/KEYWORDS.md#propertynames) -- [for all types](https://github.com/epoberezkin/ajv/blob/master/KEYWORDS.md#keywords-for-all-types) - enum, [const](https://github.com/epoberezkin/ajv/blob/master/KEYWORDS.md#const) -- [compound keywords](https://github.com/epoberezkin/ajv/blob/master/KEYWORDS.md#compound-keywords) - not, oneOf, anyOf, allOf - -With [ajv-keywords](https://github.com/epoberezkin/ajv-keywords) package Ajv also supports validation keywords from [JSON Schema extension proposals](https://github.com/json-schema/json-schema/wiki/v5-Proposals) for JSON-schema standard: - -- [switch](https://github.com/epoberezkin/ajv/blob/master/KEYWORDS.md#switch-proposed) - conditional validation with a sequence of if/then clauses -- [patternRequired](https://github.com/epoberezkin/ajv/blob/master/KEYWORDS.md#patternrequired-proposed) - like `required` but with patterns that some property should match. -- [formatMaximum, formatMinimum, formatExclusiveMaximum, formatExclusiveMinimum](https://github.com/epoberezkin/ajv/blob/master/KEYWORDS.md#formatmaximum--formatminimum-and-exclusiveformatmaximum--exclusiveformatminimum-proposed) - setting limits for date, time, etc. - -See [JSON Schema validation keywords](https://github.com/epoberezkin/ajv/blob/master/KEYWORDS.md) for more details. - - -## Formats - -The following formats are supported for string validation with "format" keyword: - -- _date_: full-date according to [RFC3339](http://tools.ietf.org/html/rfc3339#section-5.6). -- _time_: time with optional time-zone. -- _date-time_: date-time from the same source (time-zone is mandatory). `date`, `time` and `date-time` validate ranges in `full` mode and only regexp in `fast` mode (see [options](#options)). -- _uri_: full uri with optional protocol. -- _url_: [URL record](https://url.spec.whatwg.org/#concept-url). -- _uri-template_: URI template according to [RFC6570](https://tools.ietf.org/html/rfc6570) -- _email_: email address. -- _hostname_: host name according to [RFC1034](http://tools.ietf.org/html/rfc1034#section-3.5). -- _ipv4_: IP address v4. -- _ipv6_: IP address v6. -- _regex_: tests whether a string is a valid regular expression by passing it to RegExp constructor. -- _uuid_: Universally Unique IDentifier according to [RFC4122](http://tools.ietf.org/html/rfc4122). -- _json-pointer_: JSON-pointer according to [RFC6901](https://tools.ietf.org/html/rfc6901). -- _relative-json-pointer_: relative JSON-pointer according to [this draft](http://tools.ietf.org/html/draft-luff-relative-json-pointer-00). - -There are two modes of format validation: `fast` and `full`. This mode affects formats `date`, `time`, `date-time`, `uri`, `email`, and `hostname`. See [Options](#options) for details. - -You can add additional formats and replace any of the formats above using [addFormat](#api-addformat) method. - -The option `unknownFormats` allows changing the default behaviour when an unknown format is encountered. In this case Ajv can either fail schema compilation (default) or ignore it (default in versions before 5.0.0). You also can whitelist specific format(s) to be ignored. See [Options](#options) for details. - -You can find patterns used for format validation and the sources that were used in [formats.js](https://github.com/epoberezkin/ajv/blob/master/lib/compile/formats.js). - - -## Combining schemas with $ref - -You can structure your validation logic across multiple schema files and have schemas reference each other using `$ref` keyword. - -Example: - -```javascript -var schema = { - "$id": "http://example.com/schemas/schema.json", - "type": "object", - "properties": { - "foo": { "$ref": "defs.json#/definitions/int" }, - "bar": { "$ref": "defs.json#/definitions/str" } - } -}; - -var defsSchema = { - "$id": "http://example.com/schemas/defs.json", - "definitions": { - "int": { "type": "integer" }, - "str": { "type": "string" } - } -}; -``` - -Now to compile your schema you can either pass all schemas to Ajv instance: - -```javascript -var ajv = new Ajv({schemas: [schema, defsSchema]}); -var validate = ajv.getSchema('http://example.com/schemas/schema.json'); -``` - -or use `addSchema` method: - -```javascript -var ajv = new Ajv; -var validate = ajv.addSchema(defsSchema) - .compile(schema); -``` - -See [Options](#options) and [addSchema](#api) method. - -__Please note__: -- `$ref` is resolved as the uri-reference using schema $id as the base URI (see the example). -- References can be recursive (and mutually recursive) to implement the schemas for different data structures (such as linked lists, trees, graphs, etc.). -- You don't have to host your schema files at the URIs that you use as schema $id. These URIs are only used to identify the schemas, and according to JSON Schema specification validators should not expect to be able to download the schemas from these URIs. -- The actual location of the schema file in the file system is not used. -- You can pass the identifier of the schema as the second parameter of `addSchema` method or as a property name in `schemas` option. This identifier can be used instead of (or in addition to) schema $id. -- You cannot have the same $id (or the schema identifier) used for more than one schema - the exception will be thrown. -- You can implement dynamic resolution of the referenced schemas using `compileAsync` method. In this way you can store schemas in any system (files, web, database, etc.) and reference them without explicitly adding to Ajv instance. See [Asynchronous schema compilation](#asynchronous-schema-compilation). - - -## $data reference - -With `$data` option you can use values from the validated data as the values for the schema keywords. See [proposal](https://github.com/json-schema/json-schema/wiki/$data-(v5-proposal)) for more information about how it works. - -`$data` reference is supported in the keywords: const, enum, format, maximum/minimum, exclusiveMaximum / exclusiveMinimum, maxLength / minLength, maxItems / minItems, maxProperties / minProperties, formatMaximum / formatMinimum, formatExclusiveMaximum / formatExclusiveMinimum, multipleOf, pattern, required, uniqueItems. - -The value of "$data" should be a [JSON-pointer](https://tools.ietf.org/html/rfc6901) to the data (the root is always the top level data object, even if the $data reference is inside a referenced subschema) or a [relative JSON-pointer](http://tools.ietf.org/html/draft-luff-relative-json-pointer-00) (it is relative to the current point in data; if the $data reference is inside a referenced subschema it cannot point to the data outside of the root level for this subschema). - -Examples. - -This schema requires that the value in property `smaller` is less or equal than the value in the property larger: - -```javascript -var ajv = new Ajv({$data: true}); - -var schema = { - "properties": { - "smaller": { - "type": "number", - "maximum": { "$data": "1/larger" } - }, - "larger": { "type": "number" } - } -}; - -var validData = { - smaller: 5, - larger: 7 -}; - -ajv.validate(schema, validData); // true -``` - -This schema requires that the properties have the same format as their field names: - -```javascript -var schema = { - "additionalProperties": { - "type": "string", - "format": { "$data": "0#" } - } -}; - -var validData = { - 'date-time': '1963-06-19T08:30:06.283185Z', - email: 'joe.bloggs@example.com' -} -``` - -`$data` reference is resolved safely - it won't throw even if some property is undefined. If `$data` resolves to `undefined` the validation succeeds (with the exclusion of `const` keyword). If `$data` resolves to incorrect type (e.g. not "number" for maximum keyword) the validation fails. - - -## $merge and $patch keywords - -With the package [ajv-merge-patch](https://github.com/epoberezkin/ajv-merge-patch) you can use the keywords `$merge` and `$patch` that allow extending JSON-schemas with patches using formats [JSON Merge Patch (RFC 7396)](https://tools.ietf.org/html/rfc7396) and [JSON Patch (RFC 6902)](https://tools.ietf.org/html/rfc6902). - -To add keywords `$merge` and `$patch` to Ajv instance use this code: - -```javascript -require('ajv-merge-patch')(ajv); -``` - -Examples. - -Using `$merge`: - -```json -{ - "$merge": { - "source": { - "type": "object", - "properties": { "p": { "type": "string" } }, - "additionalProperties": false - }, - "with": { - "properties": { "q": { "type": "number" } } - } - } -} -``` - -Using `$patch`: - -```json -{ - "$patch": { - "source": { - "type": "object", - "properties": { "p": { "type": "string" } }, - "additionalProperties": false - }, - "with": [ - { "op": "add", "path": "/properties/q", "value": { "type": "number" } } - ] - } -} -``` - -The schemas above are equivalent to this schema: - -```json -{ - "type": "object", - "properties": { - "p": { "type": "string" }, - "q": { "type": "number" } - }, - "additionalProperties": false -} -``` - -The properties `source` and `with` in the keywords `$merge` and `$patch` can use absolute or relative `$ref` to point to other schemas previously added to the Ajv instance or to the fragments of the current schema. - -See the package [ajv-merge-patch](https://github.com/epoberezkin/ajv-merge-patch) for more information. - - -## Defining custom keywords - -The advantages of using custom keywords are: - -- allow creating validation scenarios that cannot be expressed using JSON Schema -- simplify your schemas -- help bringing a bigger part of the validation logic to your schemas -- make your schemas more expressive, less verbose and closer to your application domain -- implement custom data processors that modify your data (`modifying` option MUST be used in keyword definition) and/or create side effects while the data is being validated - -If a keyword is used only for side-effects and its validation result is pre-defined, use option `valid: true/false` in keyword definition to simplify both generated code (no error handling in case of `valid: true`) and your keyword functions (no need to return any validation result). - -The concerns you have to be aware of when extending JSON-schema standard with custom keywords are the portability and understanding of your schemas. You will have to support these custom keywords on other platforms and to properly document these keywords so that everybody can understand them in your schemas. - -You can define custom keywords with [addKeyword](#api-addkeyword) method. Keywords are defined on the `ajv` instance level - new instances will not have previously defined keywords. - -Ajv allows defining keywords with: -- validation function -- compilation function -- macro function -- inline compilation function that should return code (as string) that will be inlined in the currently compiled schema. - -Example. `range` and `exclusiveRange` keywords using compiled schema: - -```javascript -ajv.addKeyword('range', { - type: 'number', - compile: function (sch, parentSchema) { - var min = sch[0]; - var max = sch[1]; - - return parentSchema.exclusiveRange === true - ? function (data) { return data > min && data < max; } - : function (data) { return data >= min && data <= max; } - } -}); - -var schema = { "range": [2, 4], "exclusiveRange": true }; -var validate = ajv.compile(schema); -console.log(validate(2.01)); // true -console.log(validate(3.99)); // true -console.log(validate(2)); // false -console.log(validate(4)); // false -``` - -Several custom keywords (typeof, instanceof, range and propertyNames) are defined in [ajv-keywords](https://github.com/epoberezkin/ajv-keywords) package - they can be used for your schemas and as a starting point for your own custom keywords. - -See [Defining custom keywords](https://github.com/epoberezkin/ajv/blob/master/CUSTOM.md) for more details. - - -## Asynchronous schema compilation - -During asynchronous compilation remote references are loaded using supplied function. See `compileAsync` [method](#api-compileAsync) and `loadSchema` [option](#options). - -Example: - -```javascript -var ajv = new Ajv({ loadSchema: loadSchema }); - -ajv.compileAsync(schema).then(function (validate) { - var valid = validate(data); - // ... -}); - -function loadSchema(uri) { - return request.json(uri).then(function (res) { - if (res.statusCode >= 400) - throw new Error('Loading error: ' + res.statusCode); - return res.body; - }); -} -``` - -__Please note__: [Option](#options) `missingRefs` should NOT be set to `"ignore"` or `"fail"` for asynchronous compilation to work. - - -## Asynchronous validation - -Example in Node.js REPL: https://tonicdev.com/esp/ajv-asynchronous-validation - -You can define custom formats and keywords that perform validation asynchronously by accessing database or some other service. You should add `async: true` in the keyword or format definition (see [addFormat](#api-addformat), [addKeyword](#api-addkeyword) and [Defining custom keywords](#defining-custom-keywords)). - -If your schema uses asynchronous formats/keywords or refers to some schema that contains them it should have `"$async": true` keyword so that Ajv can compile it correctly. If asynchronous format/keyword or reference to asynchronous schema is used in the schema without `$async` keyword Ajv will throw an exception during schema compilation. - -__Please note__: all asynchronous subschemas that are referenced from the current or other schemas should have `"$async": true` keyword as well, otherwise the schema compilation will fail. - -Validation function for an asynchronous custom format/keyword should return a promise that resolves with `true` or `false` (or rejects with `new Ajv.ValidationError(errors)` if you want to return custom errors from the keyword function). Ajv compiles asynchronous schemas to either [es7 async functions](http://tc39.github.io/ecmascript-asyncawait/) that can optionally be transpiled with [nodent](https://github.com/MatAtBread/nodent) or with [regenerator](https://github.com/facebook/regenerator) or to [generator functions](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/function*) that can be optionally transpiled with regenerator as well. You can also supply any other transpiler as a function. See [Options](#options). - -The compiled validation function has `$async: true` property (if the schema is asynchronous), so you can differentiate these functions if you are using both synchronous and asynchronous schemas. - -If you are using generators, the compiled validation function can be either wrapped with [co](https://github.com/tj/co) (default) or returned as generator function, that can be used directly, e.g. in [koa](http://koajs.com/) 1.0. `co` is a small library, it is included in Ajv (both as npm dependency and in the browser bundle). - -Async functions are currently supported in Chrome 55, Firefox 52, Node.js 7 (with --harmony-async-await) and MS Edge 13 (with flag). - -Generator functions are currently supported in Chrome, Firefox and Node.js. - -If you are using Ajv in other browsers or in older versions of Node.js you should use one of available transpiling options. All provided async modes use global Promise class. If your platform does not have Promise you should use a polyfill that defines it. - -Validation result will be a promise that resolves with validated data or rejects with an exception `Ajv.ValidationError` that contains the array of validation errors in `errors` property. - - -Example: - -```javascript -/** - * Default mode is non-transpiled generator function wrapped with `co`. - * Using package ajv-async (https://github.com/epoberezkin/ajv-async) - * you can auto-detect the best async mode. - * In this case, without "async" and "transpile" options - * (or with option {async: true}) - * Ajv will choose the first supported/installed option in this order: - * 1. native async function - * 2. native generator function wrapped with co - * 3. es7 async functions transpiled with nodent - * 4. es7 async functions transpiled with regenerator - */ - -var setupAsync = require('ajv-async'); -var ajv = setupAsync(new Ajv); - -ajv.addKeyword('idExists', { - async: true, - type: 'number', - validate: checkIdExists -}); - - -function checkIdExists(schema, data) { - return knex(schema.table) - .select('id') - .where('id', data) - .then(function (rows) { - return !!rows.length; // true if record is found - }); -} - -var schema = { - "$async": true, - "properties": { - "userId": { - "type": "integer", - "idExists": { "table": "users" } - }, - "postId": { - "type": "integer", - "idExists": { "table": "posts" } - } - } -}; - -var validate = ajv.compile(schema); - -validate({ userId: 1, postId: 19 }) -.then(function (data) { - console.log('Data is valid', data); // { userId: 1, postId: 19 } -}) -.catch(function (err) { - if (!(err instanceof Ajv.ValidationError)) throw err; - // data is invalid - console.log('Validation errors:', err.errors); -}); -``` - -### Using transpilers with asynchronous validation functions. - -To use a transpiler you should separately install it (or load its bundle in the browser). - -Ajv npm package includes minified browser bundles of regenerator and nodent in dist folder. - - -#### Using nodent - -```javascript -var setupAsync = require('ajv-async'); -var ajv = new Ajv({ /* async: 'es7', */ transpile: 'nodent' }); -setupAsync(ajv); -var validate = ajv.compile(schema); // transpiled es7 async function -validate(data).then(successFunc).catch(errorFunc); -``` - -`npm install nodent` or use `nodent.min.js` from dist folder of npm package. - - -#### Using regenerator - -```javascript -var setupAsync = require('ajv-async'); -var ajv = new Ajv({ /* async: 'es7', */ transpile: 'regenerator' }); -setupAsync(ajv); -var validate = ajv.compile(schema); // transpiled es7 async function -validate(data).then(successFunc).catch(errorFunc); -``` - -`npm install regenerator` or use `regenerator.min.js` from dist folder of npm package. - - -#### Using other transpilers - -```javascript -var ajv = new Ajv({ async: 'es7', processCode: transpileFunc }); -var validate = ajv.compile(schema); // transpiled es7 async function -validate(data).then(successFunc).catch(errorFunc); -``` - -See [Options](#options). - - -#### Comparison of async modes - -|mode|transpile

It happens because while the first subschema in `oneOf` is validated, the property `bar` is removed because it is an additional property according to the standard (because it is not included in `properties` keyword in the same schema). - -While this behaviour is unexpected (issues [#129](https://github.com/epoberezkin/ajv/issues/129), [#134](https://github.com/epoberezkin/ajv/issues/134)), it is correct. To have the expected behaviour (both objects are allowed and additional properties are removed) the schema has to be refactored in this way: - -```json -{ - "type": "object", - "properties": { - "foo": { "type": "string" }, - "bar": { "type": "integer" } - }, - "additionalProperties": false, - "oneOf": [ - { "required": [ "foo" ] }, - { "required": [ "bar" ] } - ] -} -``` - -The schema above is also more efficient - it will compile into a faster function. - - -## Assigning defaults - -With [option `useDefaults`](#options) Ajv will assign values from `default` keyword in the schemas of `properties` and `items` (when it is the array of schemas) to the missing properties and items. - -This option modifies original data. - -__Please note__: by default the default value is inserted in the generated validation code as a literal (starting from v4.0), so the value inserted in the data will be the deep clone of the default in the schema. - -If you need to insert the default value in the data by reference pass the option `useDefaults: "shared"`. - -Inserting defaults by reference can be faster (in case you have an object in `default`) and it allows to have dynamic values in defaults, e.g. timestamp, without recompiling the schema. The side effect is that modifying the default value in any validated data instance will change the default in the schema and in other validated data instances. See example 3 below. - - -Example 1 (`default` in `properties`): - -```javascript -var ajv = new Ajv({ useDefaults: true }); -var schema = { - "type": "object", - "properties": { - "foo": { "type": "number" }, - "bar": { "type": "string", "default": "baz" } - }, - "required": [ "foo", "bar" ] -}; - -var data = { "foo": 1 }; - -var validate = ajv.compile(schema); - -console.log(validate(data)); // true -console.log(data); // { "foo": 1, "bar": "baz" } -``` - -Example 2 (`default` in `items`): - -```javascript -var schema = { - "type": "array", - "items": [ - { "type": "number" }, - { "type": "string", "default": "foo" } - ] -} - -var data = [ 1 ]; - -var validate = ajv.compile(schema); - -console.log(validate(data)); // true -console.log(data); // [ 1, "foo" ] -``` - -Example 3 (inserting "defaults" by reference): - -```javascript -var ajv = new Ajv({ useDefaults: 'shared' }); - -var schema = { - properties: { - foo: { - default: { bar: 1 } - } - } -} - -var validate = ajv.compile(schema); - -var data = {}; -console.log(validate(data)); // true -console.log(data); // { foo: { bar: 1 } } - -data.foo.bar = 2; - -var data2 = {}; -console.log(validate(data2)); // true -console.log(data2); // { foo: { bar: 2 } } -``` - -`default` keywords in other cases are ignored: - -- not in `properties` or `items` subschemas -- in schemas inside `anyOf`, `oneOf` and `not` (see [#42](https://github.com/epoberezkin/ajv/issues/42)) -- in `if` subschema of `switch` keyword -- in schemas generated by custom macro keywords - - -## Coercing data types - -When you are validating user inputs all your data properties are usually strings. The option `coerceTypes` allows you to have your data types coerced to the types specified in your schema `type` keywords, both to pass the validation and to use the correctly typed data afterwards. - -This option modifies original data. - -__Please note__: if you pass a scalar value to the validating function its type will be coerced and it will pass the validation, but the value of the variable you pass won't be updated because scalars are passed by value. - - -Example 1: - -```javascript -var ajv = new Ajv({ coerceTypes: true }); -var schema = { - "type": "object", - "properties": { - "foo": { "type": "number" }, - "bar": { "type": "boolean" } - }, - "required": [ "foo", "bar" ] -}; - -var data = { "foo": "1", "bar": "false" }; - -var validate = ajv.compile(schema); - -console.log(validate(data)); // true -console.log(data); // { "foo": 1, "bar": false } -``` - -Example 2 (array coercions): - -```javascript -var ajv = new Ajv({ coerceTypes: 'array' }); -var schema = { - "properties": { - "foo": { "type": "array", "items": { "type": "number" } }, - "bar": { "type": "boolean" } - } -}; - -var data = { "foo": "1", "bar": ["false"] }; - -var validate = ajv.compile(schema); - -console.log(validate(data)); // true -console.log(data); // { "foo": [1], "bar": false } -``` - -The coercion rules, as you can see from the example, are different from JavaScript both to validate user input as expected and to have the coercion reversible (to correctly validate cases where different types are defined in subschemas of "anyOf" and other compound keywords). - -See [Coercion rules](https://github.com/epoberezkin/ajv/blob/master/COERCION.md) for details. - - -## API - -##### new Ajv(Object options) -> Object - -Create Ajv instance. - - -##### .compile(Object schema) -> Function<Object data> - -Generate validating function and cache the compiled schema for future use. - -Validating function returns boolean and has properties `errors` with the errors from the last validation (`null` if there were no errors) and `schema` with the reference to the original schema. - -Unless the option `validateSchema` is false, the schema will be validated against meta-schema and if schema is invalid the error will be thrown. See [options](#options). - - -##### .compileAsync(Object schema [, Boolean meta] [, Function callback]) -> Promise - -Asynchronous version of `compile` method that loads missing remote schemas using asynchronous function in `options.loadSchema`. This function returns a Promise that resolves to a validation function. An optional callback passed to `compileAsync` will be called with 2 parameters: error (or null) and validating function. The returned promise will reject (and the callback will be called with an error) when: - -- missing schema can't be loaded (`loadSchema` returns a Promise that rejects). -- a schema containing a missing reference is loaded, but the reference cannot be resolved. -- schema (or some loaded/referenced schema) is invalid. - -The function compiles schema and loads the first missing schema (or meta-schema) until all missing schemas are loaded. - -You can asynchronously compile meta-schema by passing `true` as the second parameter. - -See example in [Asynchronous compilation](#asynchronous-schema-compilation). - - -##### .validate(Object schema|String key|String ref, data) -> Boolean - -Validate data using passed schema (it will be compiled and cached). - -Instead of the schema you can use the key that was previously passed to `addSchema`, the schema id if it was present in the schema or any previously resolved reference. - -Validation errors will be available in the `errors` property of Ajv instance (`null` if there were no errors). - -__Please note__: every time this method is called the errors are overwritten so you need to copy them to another variable if you want to use them later. - -If the schema is asynchronous (has `$async` keyword on the top level) this method returns a Promise. See [Asynchronous validation](#asynchronous-validation). - - -##### .addSchema(Array<Object>|Object schema [, String key]) -> Ajv - -Add schema(s) to validator instance. This method does not compile schemas (but it still validates them). Because of that dependencies can be added in any order and circular dependencies are supported. It also prevents unnecessary compilation of schemas that are containers for other schemas but not used as a whole. - -Array of schemas can be passed (schemas should have ids), the second parameter will be ignored. - -Key can be passed that can be used to reference the schema and will be used as the schema id if there is no id inside the schema. If the key is not passed, the schema id will be used as the key. - - -Once the schema is added, it (and all the references inside it) can be referenced in other schemas and used to validate data. - -Although `addSchema` does not compile schemas, explicit compilation is not required - the schema will be compiled when it is used first time. - -By default the schema is validated against meta-schema before it is added, and if the schema does not pass validation the exception is thrown. This behaviour is controlled by `validateSchema` option. - -__Please note__: Ajv uses the [method chaining syntax](https://en.wikipedia.org/wiki/Method_chaining) for all methods with the prefix `add*` and `remove*`. -This allows you to do nice things like the following. - -```javascript -var validate = new Ajv().addSchema(schema).addFormat(name, regex).getSchema(uri); -``` - -##### .addMetaSchema(Array<Object>|Object schema [, String key]) -> Ajv - -Adds meta schema(s) that can be used to validate other schemas. That function should be used instead of `addSchema` because there may be instance options that would compile a meta schema incorrectly (at the moment it is `removeAdditional` option). - -There is no need to explicitly add draft 6 meta schema (http://json-schema.org/draft-06/schema and http://json-schema.org/schema) - it is added by default, unless option `meta` is set to `false`. You only need to use it if you have a changed meta-schema that you want to use to validate your schemas. See `validateSchema`. - - -##### .validateSchema(Object schema) -> Boolean - -Validates schema. This method should be used to validate schemas rather than `validate` due to the inconsistency of `uri` format in JSON Schema standard. - -By default this method is called automatically when the schema is added, so you rarely need to use it directly. - -If schema doesn't have `$schema` property, it is validated against draft 6 meta-schema (option `meta` should not be false). - -If schema has `$schema` property, then the schema with this id (that should be previously added) is used to validate passed schema. - -Errors will be available at `ajv.errors`. - - -##### .getSchema(String key) -> Function<Object data> - -Retrieve compiled schema previously added with `addSchema` by the key passed to `addSchema` or by its full reference (id). The returned validating function has `schema` property with the reference to the original schema. - - -##### .removeSchema([Object schema|String key|String ref|RegExp pattern]) -> Ajv - -Remove added/cached schema. Even if schema is referenced by other schemas it can be safely removed as dependent schemas have local references. - -Schema can be removed using: -- key passed to `addSchema` -- it's full reference (id) -- RegExp that should match schema id or key (meta-schemas won't be removed) -- actual schema object that will be stable-stringified to remove schema from cache - -If no parameter is passed all schemas but meta-schemas will be removed and the cache will be cleared. - - -##### .addFormat(String name, String|RegExp|Function|Object format) -> Ajv - -Add custom format to validate strings or numbers. It can also be used to replace pre-defined formats for Ajv instance. - -Strings are converted to RegExp. - -Function should return validation result as `true` or `false`. - -If object is passed it should have properties `validate`, `compare` and `async`: - -- _validate_: a string, RegExp or a function as described above. -- _compare_: an optional comparison function that accepts two strings and compares them according to the format meaning. This function is used with keywords `formatMaximum`/`formatMinimum` (defined in [ajv-keywords](https://github.com/epoberezkin/ajv-keywords) package). It should return `1` if the first value is bigger than the second value, `-1` if it is smaller and `0` if it is equal. -- _async_: an optional `true` value if `validate` is an asynchronous function; in this case it should return a promise that resolves with a value `true` or `false`. -- _type_: an optional type of data that the format applies to. It can be `"string"` (default) or `"number"` (see https://github.com/epoberezkin/ajv/issues/291#issuecomment-259923858). If the type of data is different, the validation will pass. - -Custom formats can be also added via `formats` option. - - -##### .addKeyword(String keyword, Object definition) -> Ajv - -Add custom validation keyword to Ajv instance. - -Keyword should be different from all standard JSON schema keywords and different from previously defined keywords. There is no way to redefine keywords or to remove keyword definition from the instance. - -Keyword must start with a letter, `_` or `$`, and may continue with letters, numbers, `_`, `$`, or `-`. -It is recommended to use an application-specific prefix for keywords to avoid current and future name collisions. - -Example Keywords: -- `"xyz-example"`: valid, and uses prefix for the xyz project to avoid name collisions. -- `"example"`: valid, but not recommended as it could collide with future versions of JSON schema etc. -- `"3-example"`: invalid as numbers are not allowed to be the first character in a keyword - -Keyword definition is an object with the following properties: - -- _type_: optional string or array of strings with data type(s) that the keyword applies to. If not present, the keyword will apply to all types. -- _validate_: validating function -- _compile_: compiling function -- _macro_: macro function -- _inline_: compiling function that returns code (as string) -- _schema_: an optional `false` value used with "validate" keyword to not pass schema -- _metaSchema_: an optional meta-schema for keyword schema -- _modifying_: `true` MUST be passed if keyword modifies data -- _valid_: pass `true`/`false` to pre-define validation result, the result returned from validation function will be ignored. This option cannot be used with macro keywords. -- _$data_: an optional `true` value to support [$data reference](#data-reference) as the value of custom keyword. The reference will be resolved at validation time. If the keyword has meta-schema it would be extended to allow $data and it will be used to validate the resolved value. Supporting $data reference requires that keyword has validating function (as the only option or in addition to compile, macro or inline function). -- _async_: an optional `true` value if the validation function is asynchronous (whether it is compiled or passed in _validate_ property); in this case it should return a promise that resolves with a value `true` or `false`. This option is ignored in case of "macro" and "inline" keywords. -- _errors_: an optional boolean indicating whether keyword returns errors. If this property is not set Ajv will determine if the errors were set in case of failed validation. - -_compile_, _macro_ and _inline_ are mutually exclusive, only one should be used at a time. _validate_ can be used separately or in addition to them to support $data reference. - -__Please note__: If the keyword is validating data type that is different from the type(s) in its definition, the validation function will not be called (and expanded macro will not be used), so there is no need to check for data type inside validation function or inside schema returned by macro function (unless you want to enforce a specific type and for some reason do not want to use a separate `type` keyword for that). In the same way as standard keywords work, if the keyword does not apply to the data type being validated, the validation of this keyword will succeed. - -See [Defining custom keywords](#defining-custom-keywords) for more details. - - -##### .getKeyword(String keyword) -> Object|Boolean - -Returns custom keyword definition, `true` for pre-defined keywords and `false` if the keyword is unknown. - - -##### .removeKeyword(String keyword) -> Ajv - -Removes custom or pre-defined keyword so you can redefine them. - -While this method can be used to extend pre-defined keywords, it can also be used to completely change their meaning - it may lead to unexpected results. - -__Please note__: schemas compiled before the keyword is removed will continue to work without changes. To recompile schemas use `removeSchema` method and compile them again. - - -##### .errorsText([Array<Object> errors [, Object options]]) -> String - -Returns the text with all errors in a String. - -Options can have properties `separator` (string used to separate errors, ", " by default) and `dataVar` (the variable name that dataPaths are prefixed with, "data" by default). - - -## Options - -Defaults: - -```javascript -{ - // validation and reporting options: - $data: false, - allErrors: false, - verbose: false, - jsonPointers: false, - uniqueItems: true, - unicode: true, - format: 'fast', - formats: {}, - unknownFormats: true, - schemas: {}, - logger: undefined, - // referenced schema options: - schemaId: undefined // recommended '$id' - missingRefs: true, - extendRefs: 'ignore', // recommended 'fail' - loadSchema: undefined, // function(uri: string): Promise {} - // options to modify validated data: - removeAdditional: false, - useDefaults: false, - coerceTypes: false, - // asynchronous validation options: - async: 'co*', - transpile: undefined, // requires ajv-async package - // advanced options: - meta: true, - validateSchema: true, - addUsedSchema: true, - inlineRefs: true, - passContext: false, - loopRequired: Infinity, - ownProperties: false, - multipleOfPrecision: false, - errorDataPath: 'object', - messages: true, - sourceCode: false, - processCode: undefined, // function (str: string): string {} - cache: new Cache, - serialize: undefined -} -``` - -##### Validation and reporting options - -- _$data_: support [$data references](#data-reference). Draft 6 meta-schema that is added by default will be extended to allow them. If you want to use another meta-schema you need to use $dataMetaSchema method to add support for $data reference. See [API](#api). -- _allErrors_: check all rules collecting all errors. Default is to return after the first error. -- _verbose_: include the reference to the part of the schema (`schema` and `parentSchema`) and validated data in errors (false by default). -- _jsonPointers_: set `dataPath` property of errors using [JSON Pointers](https://tools.ietf.org/html/rfc6901) instead of JavaScript property access notation. -- _uniqueItems_: validate `uniqueItems` keyword (true by default). -- _unicode_: calculate correct length of strings with unicode pairs (true by default). Pass `false` to use `.length` of strings that is faster, but gives "incorrect" lengths of strings with unicode pairs - each unicode pair is counted as two characters. -- _format_: formats validation mode ('fast' by default). Pass 'full' for more correct and slow validation or `false` not to validate formats at all. E.g., 25:00:00 and 2015/14/33 will be invalid time and date in 'full' mode but it will be valid in 'fast' mode. -- _formats_: an object with custom formats. Keys and values will be passed to `addFormat` method. -- _unknownFormats_: handling of unknown formats. Option values: - - `true` (default) - if an unknown format is encountered the exception is thrown during schema compilation. If `format` keyword value is [$data reference](#data-reference) and it is unknown the validation will fail. - - `[String]` - an array of unknown format names that will be ignored. This option can be used to allow usage of third party schemas with format(s) for which you don't have definitions, but still fail if another unknown format is used. If `format` keyword value is [$data reference](#data-reference) and it is not in this array the validation will fail. - - `"ignore"` - to log warning during schema compilation and always pass validation (the default behaviour in versions before 5.0.0). This option is not recommended, as it allows to mistype format name and it won't be validated without any error message. This behaviour is required by JSON-schema specification. -- _schemas_: an array or object of schemas that will be added to the instance. In case you pass the array the schemas must have IDs in them. When the object is passed the method `addSchema(value, key)` will be called for each schema in this object. -- _logger_: sets the logging method. Default is the global `console` object that should have methods `log`, `warn` and `error`. Option values: - - custom logger - it should have methods `log`, `warn` and `error`. If any of these methods is missing an exception will be thrown. - - `false` - logging is disabled. - - -##### Referenced schema options - -- _schemaId_: this option defines which keywords are used as schema URI. Option value: - - `"$id"` (recommended) - only use `$id` keyword as schema URI (as specified in JSON Schema draft-06), ignore `id` keyword (if it is present a warning will be logged). - - `"id"` - only use `id` keyword as schema URI (as specified in JSON Schema draft-04), ignore `$id` keyword (if it is present a warning will be logged). - - `undefined` (default) - use both `$id` and `id` keywords as schema URI. If both are present (in the same schema object) and different the exception will be thrown during schema compilation. -- _missingRefs_: handling of missing referenced schemas. Option values: - - `true` (default) - if the reference cannot be resolved during compilation the exception is thrown. The thrown error has properties `missingRef` (with hash fragment) and `missingSchema` (without it). Both properties are resolved relative to the current base id (usually schema id, unless it was substituted). - - `"ignore"` - to log error during compilation and always pass validation. - - `"fail"` - to log error and successfully compile schema but fail validation if this rule is checked. -- _extendRefs_: validation of other keywords when `$ref` is present in the schema. Option values: - - `"ignore"` (default) - when `$ref` is used other keywords are ignored (as per [JSON Reference](https://tools.ietf.org/html/draft-pbryan-zyp-json-ref-03#section-3) standard). A warning will be logged during the schema compilation. - - `"fail"` (recommended) - if other validation keywords are used together with `$ref` the exception will be thrown when the schema is compiled. This option is recommended to make sure schema has no keywords that are ignored, which can be confusing. - - `true` - validate all keywords in the schemas with `$ref` (the default behaviour in versions before 5.0.0). -- _loadSchema_: asynchronous function that will be used to load remote schemas when `compileAsync` [method](#api-compileAsync) is used and some reference is missing (option `missingRefs` should NOT be 'fail' or 'ignore'). This function should accept remote schema uri as a parameter and return a Promise that resolves to a schema. See example in [Asynchronous compilation](#asynchronous-schema-compilation). - - -##### Options to modify validated data - -- _removeAdditional_: remove additional properties - see example in [Filtering data](#filtering-data). This option is not used if schema is added with `addMetaSchema` method. Option values: - - `false` (default) - not to remove additional properties - - `"all"` - all additional properties are removed, regardless of `additionalProperties` keyword in schema (and no validation is made for them). - - `true` - only additional properties with `additionalProperties` keyword equal to `false` are removed. - - `"failing"` - additional properties that fail schema validation will be removed (where `additionalProperties` keyword is `false` or schema). -- _useDefaults_: replace missing properties and items with the values from corresponding `default` keywords. Default behaviour is to ignore `default` keywords. This option is not used if schema is added with `addMetaSchema` method. See examples in [Assigning defaults](#assigning-defaults). Option values: - - `false` (default) - do not use defaults - - `true` - insert defaults by value (safer and slower, object literal is used). - - `"shared"` - insert defaults by reference (faster). If the default is an object, it will be shared by all instances of validated data. If you modify the inserted default in the validated data, it will be modified in the schema as well. -- _coerceTypes_: change data type of data to match `type` keyword. See the example in [Coercing data types](#coercing-data-types) and [coercion rules](https://github.com/epoberezkin/ajv/blob/master/COERCION.md). Option values: - - `false` (default) - no type coercion. - - `true` - coerce scalar data types. - - `"array"` - in addition to coercions between scalar types, coerce scalar data to an array with one element and vice versa (as required by the schema). - - -##### Asynchronous validation options - -- _async_: determines how Ajv compiles asynchronous schemas (see [Asynchronous validation](#asynchronous-validation)) to functions. Option values: - - `"*"` / `"co*"` (default) - compile to generator function ("co*" - wrapped with `co.wrap`). If generators are not supported and you don't provide `processCode` option (or `transpile` option if you use [ajv-async](https://github.com/epoberezkin/ajv-async) package), the exception will be thrown when async schema is compiled. - - `"es7"` - compile to es7 async function. Unless your platform supports them you need to provide `processCode` or `transpile` option. According to [compatibility table](http://kangax.github.io/compat-table/es7/)) async functions are supported by: - - Firefox 52, - - Chrome 55, - - Node.js 7 (with `--harmony-async-await`), - - MS Edge 13 (with flag). - - `undefined`/`true` - auto-detect async mode. It requires [ajv-async](https://github.com/epoberezkin/ajv-async) package. If `transpile` option is not passed, ajv-async will choose the first of supported/installed async/transpile modes in this order: - - "es7" (native async functions), - - "co*" (native generators with co.wrap), - - "es7"/"nodent", - - "co*"/"regenerator" during the creation of the Ajv instance. - - If none of the options is available the exception will be thrown. -- _transpile_: Requires [ajv-async](https://github.com/epoberezkin/ajv-async) package. It determines whether Ajv transpiles compiled asynchronous validation function. Option values: - - `"nodent"` - transpile with [nodent](https://github.com/MatAtBread/nodent). If nodent is not installed, the exception will be thrown. nodent can only transpile es7 async functions; it will enforce this mode. - - `"regenerator"` - transpile with [regenerator](https://github.com/facebook/regenerator). If regenerator is not installed, the exception will be thrown. - - a function - this function should accept the code of validation function as a string and return transpiled code. This option allows you to use any other transpiler you prefer. If you are passing a function, you can simply pass it to `processCode` option without using ajv-async. - - -##### Advanced options - -- _meta_: add [meta-schema](http://json-schema.org/documentation.html) so it can be used by other schemas (true by default). If an object is passed, it will be used as the default meta-schema for schemas that have no `$schema` keyword. This default meta-schema MUST have `$schema` keyword. -- _validateSchema_: validate added/compiled schemas against meta-schema (true by default). `$schema` property in the schema can either be http://json-schema.org/schema or http://json-schema.org/draft-04/schema or absent (draft-4 meta-schema will be used) or can be a reference to the schema previously added with `addMetaSchema` method. Option values: - - `true` (default) - if the validation fails, throw the exception. - - `"log"` - if the validation fails, log error. - - `false` - skip schema validation. -- _addUsedSchema_: by default methods `compile` and `validate` add schemas to the instance if they have `$id` (or `id`) property that doesn't start with "#". If `$id` is present and it is not unique the exception will be thrown. Set this option to `false` to skip adding schemas to the instance and the `$id` uniqueness check when these methods are used. This option does not affect `addSchema` method. -- _inlineRefs_: Affects compilation of referenced schemas. Option values: - - `true` (default) - the referenced schemas that don't have refs in them are inlined, regardless of their size - that substantially improves performance at the cost of the bigger size of compiled schema functions. - - `false` - to not inline referenced schemas (they will be compiled as separate functions). - - integer number - to limit the maximum number of keywords of the schema that will be inlined. -- _passContext_: pass validation context to custom keyword functions. If this option is `true` and you pass some context to the compiled validation function with `validate.call(context, data)`, the `context` will be available as `this` in your custom keywords. By default `this` is Ajv instance. -- _loopRequired_: by default `required` keyword is compiled into a single expression (or a sequence of statements in `allErrors` mode). In case of a very large number of properties in this keyword it may result in a very big validation function. Pass integer to set the number of properties above which `required` keyword will be validated in a loop - smaller validation function size but also worse performance. -- _ownProperties_: by default Ajv iterates over all enumerable object properties; when this option is `true` only own enumerable object properties (i.e. found directly on the object rather than on its prototype) are iterated. Contributed by @mbroadst. -- _multipleOfPrecision_: by default `multipleOf` keyword is validated by comparing the result of division with parseInt() of that result. It works for dividers that are bigger than 1. For small dividers such as 0.01 the result of the division is usually not integer (even when it should be integer, see issue [#84](https://github.com/epoberezkin/ajv/issues/84)). If you need to use fractional dividers set this option to some positive integer N to have `multipleOf` validated using this formula: `Math.abs(Math.round(division) - division) < 1e-N` (it is slower but allows for float arithmetics deviations). -- _errorDataPath_: set `dataPath` to point to 'object' (default) or to 'property' when validating keywords `required`, `additionalProperties` and `dependencies`. -- _messages_: Include human-readable messages in errors. `true` by default. `false` can be passed when custom messages are used (e.g. with [ajv-i18n](https://github.com/epoberezkin/ajv-i18n)). -- _sourceCode_: add `sourceCode` property to validating function (for debugging; this code can be different from the result of toString call). -- _processCode_: an optional function to process generated code before it is passed to Function constructor. It can be used to either beautify (the validating function is generated without line-breaks) or to transpile code. Starting from version 5.0.0 this option replaced options: - - `beautify` that formatted the generated function using [js-beautify](https://github.com/beautify-web/js-beautify). If you want to beautify the generated code pass `require('js-beautify').js_beautify`. - - `transpile` that transpiled asynchronous validation function. You can still use `transpile` option with [ajv-async](https://github.com/epoberezkin/ajv-async) package. See [Asynchronous validation](#asynchronous-validation) for more information. -- _cache_: an optional instance of cache to store compiled schemas using stable-stringified schema as a key. For example, set-associative cache [sacjs](https://github.com/epoberezkin/sacjs) can be used. If not passed then a simple hash is used which is good enough for the common use case (a limited number of statically defined schemas). Cache should have methods `put(key, value)`, `get(key)`, `del(key)` and `clear()`. -- _serialize_: an optional function to serialize schema to cache key. Pass `false` to use schema itself as a key (e.g., if WeakMap used as a cache). By default [fast-json-stable-stringify](https://github.com/epoberezkin/fast-json-stable-stringify) is used. - - -## Validation errors - -In case of validation failure, Ajv assigns the array of errors to `errors` property of validation function (or to `errors` property of Ajv instance when `validate` or `validateSchema` methods were called). In case of [asynchronous validation](#asynchronous-validation), the returned promise is rejected with exception `Ajv.ValidationError` that has `errors` property. - - -### Error objects - -Each error is an object with the following properties: - -- _keyword_: validation keyword. -- _dataPath_: the path to the part of the data that was validated. By default `dataPath` uses JavaScript property access notation (e.g., `".prop[1].subProp"`). When the option `jsonPointers` is true (see [Options](#options)) `dataPath` will be set using JSON pointer standard (e.g., `"/prop/1/subProp"`). -- _schemaPath_: the path (JSON-pointer as a URI fragment) to the schema of the keyword that failed validation. -- _params_: the object with the additional information about error that can be used to create custom error messages (e.g., using [ajv-i18n](https://github.com/epoberezkin/ajv-i18n) package). See below for parameters set by all keywords. -- _message_: the standard error message (can be excluded with option `messages` set to false). -- _schema_: the schema of the keyword (added with `verbose` option). -- _parentSchema_: the schema containing the keyword (added with `verbose` option) -- _data_: the data validated by the keyword (added with `verbose` option). - -__Please note__: `propertyNames` keyword schema validation errors have an additional property `propertyName`, `dataPath` points to the object. After schema validation for each property name, if it is invalid an additional error is added with the property `keyword` equal to `"propertyNames"`. - - -### Error parameters - -Properties of `params` object in errors depend on the keyword that failed validation. - -- `maxItems`, `minItems`, `maxLength`, `minLength`, `maxProperties`, `minProperties` - property `limit` (number, the schema of the keyword). -- `additionalItems` - property `limit` (the maximum number of allowed items in case when `items` keyword is an array of schemas and `additionalItems` is false). -- `additionalProperties` - property `additionalProperty` (the property not used in `properties` and `patternProperties` keywords). -- `dependencies` - properties: - - `property` (dependent property), - - `missingProperty` (required missing dependency - only the first one is reported currently) - - `deps` (required dependencies, comma separated list as a string), - - `depsCount` (the number of required dependencies). -- `format` - property `format` (the schema of the keyword). -- `maximum`, `minimum` - properties: - - `limit` (number, the schema of the keyword), - - `exclusive` (boolean, the schema of `exclusiveMaximum` or `exclusiveMinimum`), - - `comparison` (string, comparison operation to compare the data to the limit, with the data on the left and the limit on the right; can be "<", "<=", ">", ">=") -- `multipleOf` - property `multipleOf` (the schema of the keyword) -- `pattern` - property `pattern` (the schema of the keyword) -- `required` - property `missingProperty` (required property that is missing). -- `propertyNames` - property `propertyName` (an invalid property name). -- `patternRequired` (in ajv-keywords) - property `missingPattern` (required pattern that did not match any property). -- `type` - property `type` (required type(s), a string, can be a comma-separated list) -- `uniqueItems` - properties `i` and `j` (indices of duplicate items). -- `enum` - property `allowedValues` pointing to the array of values (the schema of the keyword). -- `$ref` - property `ref` with the referenced schema URI. -- custom keywords (in case keyword definition doesn't create errors) - property `keyword` (the keyword name). - - -## Related packages - -- [ajv-async](https://github.com/epoberezkin/ajv-async) - configure async validation mode -- [ajv-cli](https://github.com/jessedc/ajv-cli) - command line interface -- [ajv-errors](https://github.com/epoberezkin/ajv-errors) - custom error messages -- [ajv-i18n](https://github.com/epoberezkin/ajv-i18n) - internationalised error messages -- [ajv-istanbul](https://github.com/epoberezkin/ajv-istanbul) - instrument generated validation code to measure test coverage of your schemas -- [ajv-keywords](https://github.com/epoberezkin/ajv-keywords) - custom validation keywords (if/then/else, select, typeof, etc.) -- [ajv-merge-patch](https://github.com/epoberezkin/ajv-merge-patch) - keywords $merge and $patch -- [ajv-pack](https://github.com/epoberezkin/ajv-pack) - produces a compact module exporting validation functions - - -## Some packages using Ajv - -- [webpack](https://github.com/webpack/webpack) - a module bundler.
