WordPress to VuePress 2 Migration Script

This is a script that I put together in order to migrate a blog from WordPress 4.4.2 to VuePress 2. I would expect it to work with the other versions of WordPress as well, but please add a comment below and let me know.

This is not a general purpose migration tool from WordPress to VuePress. It only covers what I needed for my own individual use case. There may be better alternatives out there.

Installation

You can install it by doing the following:

$ git clone https://github.com/cinar/wordpress-to-vuepress-migration.git
$ cd wordpress-to-vuepress-migration
$ npm install

Usage

You can start it by doign the following:

$ npm run migration

The tool will ask you about your WordPress and VuePress installations. Please make sure to have your WordPress database information available. You can find it under the wp-config.php file.

Database host		WordPress MySQL database host.
Database name		WordPress MySQL database name.

VuePress Parameters

Once the information is provided, the migration will run:

Pulling the posts from WordPress

Everything pretty much comes down to this SQL query. The script uses that to extract all needed pieces, then translates the content to Markdown, as well as copying the image files to Vuepress public folder.

  u.display_name AS author,
  p.post_date AS posted,
