Install

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

npm install mdast-comment-marker

Use

import {commentMarker} from 'mdast-comment-marker'

console.log(commentMarker({
  type: 'html',
  value: '<!--foo-->'
}));

console.log(commentMarker({
  type: 'html',
  value: '<!--foo bar baz=12.4 qux="test test" quux=\'false\'-->'
}));

console.log(commentMarker({
  type: 'html',
  value: '<!doctype html>'
}));

// Also supports MDX@2 expressions:
console.log(commentMarker({
  type: 'mdxFlowExpression',
  value: '/* lint disable heading-style */'
}));

  name: 'foo',
  attributes: '',

  node: { type: 'html', value: '<!--foo-->' }

  name: 'foo',
  attributes: `bar baz=12.4 qux="test test" quux='false'`,
  parameters: { bar: true, baz: 12.4, qux: 'test test', quux: false },
  node: {
    type: 'html',
