mdast-util-gfm-task-list-item

Extension for mdast-util-from-markdown and/or mdast-util-to-markdown to support GitHub flavored markdown task list items in mdast. When parsing (from-markdown), must be combined with micromark-extension-gfm-task-list-item.

When to use this

Use this if you’re dealing with the AST manually. It’s might be better to use remark-gfm with remark, which includes this but provides a nicer interface and makes it easier to combine with hundreds of plugins.

Install

This package is ESM only: Node 12+ is needed to use it and it must be imported instead of required.

npm:

npm install mdast-util-gfm-task-list-item

Use

Say we have the following file, example.md:

* [ ] To do
* [x] Done

1. Mixed…
2. [x] …messages

And our module, example.js, looks as follows:

import fs from 'node:fs'
import {fromMarkdown} from 'mdast-util-from-markdown'
import {toMarkdown} from 'mdast-util-to-markdown'
import {gfmTaskListItem} from 'micromark-extension-gfm-task-list-item'
import {gfmTaskListItemFromMarkdown, gfmTaskListItemToMarkdown} from 'mdast-util-gfm-task-list-item'

const doc = fs.readFileSync('example.md')

const tree = fromMarkdown(doc, {
  extensions: [gfmTaskListItem],
  mdastExtensions: [gfmTaskListItemFromMarkdown]
})

console.log(tree)

const out = toMarkdown(tree, {extensions: [gfmTaskListItemToMarkdown]})

console.log(out)

Now, running node example yields (positional info removed for the sake of brevity):

{
 type: 'root',
 children: [
   {
     type: 'list',
     ordered: false,
     start: null,
     spread: false,
     children: [
       {
         type: 'listItem',
         spread: false,
         checked: false,
         children: [
           {type: 'paragraph', children: [{type: 'text', value: 'To do'}]}
         ]
       },
       {
         type: 'listItem',
         spread: false,
         checked: true,
         children: [
           {type: 'paragraph', children: [{type: 'text', value: 'Done'}]}
         ]
       }
     ]
   },
   {
     type: 'list',
     ordered: true,
     start: 1,
     spread: false,
     children: [
       {
         type: 'listItem',
         spread: false,
         checked: null,
         children: [
           {type: 'paragraph', children: [{type: 'text', value: 'Mixed…'}]}
         ]
       },
       {
         type: 'listItem',
         spread: false,
         checked: true,
         children: [
           {type: 'paragraph', children: [{type: 'text', value: '…messages'}]}
         ]
       }
     ]
   }
 ]
}

*   [ ] To do
*   [x] Done

1.  Mixed…
2.  [x] …messages
