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

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.


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


npm install mdast-util-gfm-strikethrough


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

import {fromMarkdown} from 'mdast-util-from-markdown'
import {toMarkdown} from 'mdast-util-to-markdown'
import {gfmStrikethrough} from 'micromark-extension-gfm-strikethrough'
import {gfmStrikethroughFromMarkdown, gfmStrikethroughToMarkdown} from 'mdast-util-gfm-strikethrough'

const doc = '*Emphasis*, **importance**, and ~~strikethrough~~.'

const tree = fromMarkdown(doc, {
  extensions: [gfmStrikethrough()],
  mdastExtensions: [gfmStrikethroughFromMarkdown]


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


Now, running node example yields:

  type: 'root',
  children: [
      type: 'paragraph',
      children: [
        {type: 'emphasis', children: [{type: 'text', value: 'Emphasis'}]},
        {type: 'text', value: ', '},
        {type: 'strong', children: [{type: 'text', value: 'importance'}]},
        {type: 'text', value: ', and '},
        {type: 'delete', children: [{type: 'text', value: 'strikethrough'}]},
        {type: 'text', value: '.'}
*Emphasis*, **importance**, and ~~strikethrough~~.


This package exports the following identifier: gfmStrikethroughFromMarkdown, gfmStrikethroughToMarkdown. There is no default export.



Support strikethrough. The exports are extensions, respectively for mdast-util-from-markdown and mdast-util-to-markdown.
