Warning

This is the documentation for hexo-markmap@2. If you use hexo-markmap@1, please check here

If you want to upgrade to hexo-markmap@2, please check here.

hexo-markmap

Insert a mindmap into your Hexo blog using markmap.

Install

pnpm add hexo-markmap -D

npm install hexo-markmap --save-dev

yarn add hexo-markmap --dev

Tip

Try our new VS Code extension, markmap-universe, to directly preview your hexo-markmap mindmaps.

Usage

{% markmap %}
---
options:
  colorFreezeLevel: 2
---
# Markdown
# Syntax
{% endmarkmap %}

Inline Options

You can customize each mindmap individually in the markmap tag.

Frontmatter Options

Just like you use frontmatter in your Markdown files in Hexo, you can use frontmatter in the markmap tag to customize your mindmap!

All frontmatter options are optional.

• id : Used to define the ID of the markmap-wrap element.

• markmap : Correspond to the IMarkmapJSONOptions in the markmap project. For more details, please refer to jsonOptions.

  • alias: options (for backward compatibility)

Difference between markmap and options

• markmap (from markmap-lib) Will be preprocessed (converting strings to arrays or numbers) and overrides the legacy options.

  • E.g., color: 'red' will be converted to color: ['red'], only the latter is valid in markmap-view.
  • ✅ Recommended for consistent use with markmap.

• options (from markmap-universe) Passed directly to markmap-view.

  • ❌ Not recommended, maintained only for backward compatibility.

Tag Options

You can also specify the height of the mindmap directly in the tag. By default, it will be calculated based on the content.

{% markmap 300px %}
# Markdown
# Syntax
{% endmarkmap %}

Config

Add your options to config.yml.

Convention over configuration, if you don't need any of the following features, then you don't need to add these configs.

By default, it works well. Each option has a default value.

Default options

hexo_markmap:
  darkThemeCssSelector: '.dark'
  CDN: 'fastly' 
  customCDN: 'https://fastly.jsdelivr.net/npm/'

• darkThemeCssSelector : Used to specify the CSS selector for the dark theme.
• CDN : Used to specify the CDN for Markmap. The supported values are fastly, jsdelivr, unpkg, and custom.
  • If set to custom, the customCDN value will be used as the CDN prefix.
• customCDN : Defines a custom CDN URL for Markmap. This must be a valid URL.
• globalOptions : Used to define global options for all mindmaps.
  • Correspond to the options in the frontmatter.

Upgrade to hexo-markmap v2

hexo-markmap@2 is a completely refactored version by @coderxi1 and @maxchang3. This version upgrades to the latest Markmap and introduces more customization options, including:

• Customization within a single Markmap tag using frontmatter:
  • CSS styles (custom height, width, responsive layout, etc.)
    • Since v2.0.5, setting styles in the frontmatter is no longer supported. Instead, you can define them directly within a <style> tag by combining it with the id option.
  • Markmap's JSON Options
• Automatic CDN URL generation using Markmap's built-in URL builder
• On-demand CDN resource insertion based on syntax usage
• Support for dark mode and fullscreen button
• Refactored in TypeScript with test coverage

Note that some implementation details differ from hexo-markmap@1. If you do not require these new features, you may continue using hexo-markmap@1.

To upgrade to hexo-markmap@2, follow these steps:

1. Install hexo-markmap@2 using your preferred package manager:

   pnpm add hexo-markmap@2 -D

   npm install hexo-markmap@2 --save-dev

   yarn add hexo-markmap@2 -D

2. Modify your config.yml as needed:

   • The following configuration options are no longer supported:

     hexo_markmap:
     -  pjax: false
     -  katex: false
     -  prism: false
     -  lockView: false
     -  fixSVGAttrNaN: false

     • The new version no longer supports pjax compatibility;
     • KaTeX and Prism.js are now automatically detected and generate corresponding CDN tags;
     • You can disable pan and zoom in the frontmatter options to achieve the lockView effect.

   • CDN configuration logic has also changed:

     hexo_markmap:
     -  userCDN:
     -    d3_js: https://fastly.jsdelivr.net/npm/d3@6
     -    markmap_view_js: https://fastly.jsdelivr.net/npm/[email protected]
     -    katex_css: https://fastly.jsdelivr.net/npm/[email protected]/dist/katex.min.css
     -    prism_css: https://fastly.jsdelivr.net/npm/[email protected]/themes/prism.css
     +  CDN: 'custom'
     +  customCDN: 'https://fastly.jsdelivr.net/npm/'

     • The new CDN setting supports fastly, jsdelivr, unpkg, and a custom option;
     • If you choose custom, the customCDN value will be used as the CDN prefix.

   • Additionally, the previous depth parameter for setting fold levels has been removed. Instead, you can use the initialExpandLevel option in frontmatter.

3. Update your markmap tags in your Markdown files:

   • The markmap tag now supports frontmatter options. You can specify the options directly in the tag, like this:

     {% markmap %}
     ---
     markmap:
       colorFreezeLevel: 2
     ---
     # Markdown
     # Syntax
     {% endmarkmap %}

   • You can still customize the height of the mindmap directly in the tag, by default it will be calculated based on the content:

     - {% markmap 300px %}
     + {% markmap %}
     # Markdown
     # Syntax
     {% endmarkmap %}

4. Finally, regenerate your blog.

Example

{% markmap %}
---
markmap:
  colorFreezeLevel: 2

## Features

Note that if blocks and lists appear at the same level, the lists will be ignored.

### Lists

- **strong** ~~del~~ *italic* ==highlight==
- `inline code`
- [x] checkbox
- Katex: $x = {-b \pm \sqrt{b^2-4ac} \over 2a}$ <!-- markmap: fold -->
  - [More Katex Examples](#?d=gist:af76a4c245b302206b16aec503dbe07b:katex.md)
- Now we can wrap very very very very long text based on `maxWidth` option
- Ordered list
  1. item 1
  2. item 2

### Blocks
<!-- To avoid hexo treat the following as code block, we need to use a list -->
- ```js 
  console.log('hello, JavaScript')
  ```

- | Products | Price |
  |-|-|
  | Apple | 4 |
  | Banana | 2 |
