remark plugin to compile Markdown to Virtual DOM.

Install

npm:

npm install remark-vdom

Use

Say we have the following file, example.js:

var unified = require('unified')
var markdown = require('remark-parse')
var vdom = require('remark-vdom')

unified()
  .use(markdown)
  .use(vdom)
  .process('Some _emphasis_, **importance**, and `code`.', function(err, file) {
    if (err) throw err
    console.dir(file.contents, {depth: null})
  })

Now, running node example yields:

VirtualNode {
  tagName: 'DIV',
  properties: { key: undefined },
  children: [
    VirtualNode {
      tagName: 'P',
      properties: { key: undefined },
      children: [
        VirtualText { text: 'Some ' },
        VirtualNode {
          tagName: 'EM',
          properties: { key: undefined },
          children: [ VirtualText { text: 'emphasis' } ],
          key: 'h-3',
          namespace: null,
          count: 1,
          hasWidgets: false,
          hasThunks: false,
          hooks: undefined,
          descendantHooks: false
        },
        VirtualText { text: ', ' },
        VirtualNode {
          tagName: 'STRONG',
          properties: { key: undefined },
          children: [ VirtualText { text: 'importance' } ],
          key: 'h-4',
          namespace: null,
          count: 1,
          hasWidgets: false,
          hasThunks: false,
          hooks: undefined,
          descendantHooks: false
        },
        VirtualText { text: ', and ' },
        VirtualNode {
          tagName: 'CODE',
          properties: { key: undefined },
          children: [ VirtualText { text: 'code' } ],
          key: 'h-5',
          namespace: null,
          count: 1,
          hasWidgets: false,
          hasThunks: false,
          hooks: undefined,
          descendantHooks: false
        },
        VirtualText { text: '.' }
      ],
      key: 'h-2',
      namespace: null,
      count: 10,
      hasWidgets: false,
      hasThunks: false,
      hooks: undefined,
      descendantHooks: false
    }
  ],
  key: 'h-1',
  namespace: null,
  count: 11,
  hasWidgets: false,
  hasThunks: false,
  hooks: undefined,
  descendantHooks: false
}

API

remark().use(vdom[, options])

Compile Markdown to Virtual DOM.

options
options.sanitize

How to sanitise the output (Object or boolean, default: null).

Sanitation is done by hast-util-sanitize, except when false is given. If an object is passed in, it’s given as a schema to sanitize. By default, input is sanitised according to GitHub’s sanitation rules.

Embedded HTML is always stripped.

For example, by default classNames are stripped. To keep them in, use something like:

var merge = require('deepmerge')
var gh = require('hast-util-sanitize/lib/github')

var schema = merge(gh, {attributes: {'*': ['className']}})

var vtree = remark()
  .use(vdom, {sanitize: schema})
  .processSync(/* ... */)
options.prefix

Optimisation hint (string, default: h-).

options.h

Hyperscript to use (Function, default: require('virtual-dom/h')).

options.components

Map of tag names to custom components (Object.<Function>, optional). That component is invoked with tagName, props, and children. It can return any VDOM compatible value (such as VNode, VText, Widget). For example:

var components = {code: code}

function code(tagName, props, children) {
  // Ensure a default programming language is set.
  if (!props.className) {
    props.className = 'language-js'
  }

  return h(tagName, props, children)
}

Integrations

Integrates with the same tools as remark-html.
