This package is a utility that can turn a hast syntax tree into a parse5 AST. Why not use a Parse5 adapter, you might ask? Well, because it’s more code weight to use adapters, and more fragile.

This package is useful when working with parse5, and for some reason want to generate its AST again. The inverse utility, hast-util-from-parse5, is more likely what you want.

This package is ESM only. In Node.js (version 16+), install with npm:

npm install hast-util-to-parse5

In Deno with esm.sh:

import {toParse5} from 'https://esm.sh/hast-util-to-parse5@8'

In browsers with esm.sh:

<script type="module">
  import {toParse5} from 'https://esm.sh/hast-util-to-parse5@8?bundle'
</script>

import {toParse5} from 'hast-util-to-parse5'

const tree = toParse5({
  type: 'element',
  tagName: 'h1',
  properties: {},
  children: [{type: 'text', value: 'World!'}]
})

console.log(tree)

Yields:

{ nodeName: 'h1',
  tagName: 'h1',
  attrs: [],
  namespaceURI: 'http://www.w3.org/1999/xhtml',
  childNodes: [ { nodeName: '#text', value: 'World!', parentNode: [Circular] } ] }

This package exports the identifier toParse5. There is no default export.

Transform a hast tree to a parse5 AST.

• tree (HastNode) — tree to transform
• options (Options, optional) — configuration

parse5 node (Parse5Node).

Configuration (TypeScript type).

• space (Space, optional) — which space the document is in

Namespace (TypeScript type).

type Space = 'html' | 'svg'

This package is fully typed with TypeScript. It exports the additional types Options and Space.

Projects maintained by the unified collective are compatible with maintained versions of Node.js.

When we cut a new major release, we drop support for unmaintained versions of Node. This means we try to keep the current release line, hast-util-to-parse5@^8, compatible with Node.js 16.

Use of hast-util-to-parse5 can open you up to a cross-site scripting (XSS) attack if the hast tree is unsafe.

• hast-util-from-parse5 — transform from Parse5’s AST to hast
• hast-util-to-nlcst — transform hast to nlcst
• hast-util-to-mdast — transform hast to mdast
• hast-util-to-xast — transform hast to xast
• mdast-util-to-hast — transform mdast to hast
• mdast-util-to-nlcst — transform mdast to nlcst
