If you want to use Vue.js to render mdast, use it. It is especially useful when you want to render streamed MarkDown strings in AI application development.

Install

npm install mdast-util-to-vnode

Use

Say we have the following markdown file example.md:

# Heading

`mdast-util-to-vnode` is a mdast utility to get the vue vnode.

And our module example.js looks as follows:

import fs from 'node:fs/promises'
import { fromMarkdown } from 'mdast-util-from-markdown'
import { toVNode } from 'mdast-util-to-vnode'

const doc = await fs.readFile('example.md')
const vnode = toVNode(fromMarkdown(doc))

console.log(vnode)

Now running node example.js yields (some info removed for brevity):

{
  "type": "div",
  "props": null,
  "key": null,
  "children": [
    {
      "type": "h1",
      "props": null,
      "key": null,
      "children": [
        {
          "props": null,
          "key": null,
          "children": "Heading"
        }
      ]
    },
    {
      "type": "p",
      "props": null,
      "key": null,
      "children": [
        {
          "type": "code",
          "props": null,
          "key": null,
          "children": "mdast-util-to-vnode"
        },
        {
          "props": null,
          "key": null,
          "children": " is a mdast utility to get the vue vnode."
        }
      ]
    }
  ]
}
