What is this?
This is like rehype-parse but for browsers.
This plugin uses DOM APIs to do its work, which makes it smaller in browsers, at
the cost of not supporting positional info on nodes.
When should I use this?
Use this package when you want to use rehype-parse solely in browsers.
See the monorepo readme for info on when to use rehype-dom.
This plugin is built on hast-util-from-dom, which is a
low level tool to turn DOM nodes into hast syntax trees.
rehype focusses on making it easier to transform content by abstracting such
internals away.
Install
This package is ESM only. In Node.js (version 16+), install with npm:
npm install rehype-dom-parse
In Deno with esm.sh:
import rehypeDomParse from 'https://esm.sh/rehype-dom-parse@5'
In browsers with esm.sh:
<script type="module">
import rehypeDomParse from 'https://esm.sh/rehype-dom-parse@5?bundle'
</script>
Use
Say our page example.html contains:
<!doctype html>
<title>Example</title>
<body>
<script type="module">
import rehypeDomParse from 'https://esm.sh/rehype-dom-parse@5?bundle'
import rehypeRemark from 'https://esm.sh/rehype-remark@10?bundle'
import remarkStringify from 'https://esm.sh/remark-stringify@11?bundle'
import {unified} from 'https://esm.sh/unified@11?bundle'
const file = await unified()
.use(rehypeDomParse)
.use(rehypeRemark)
.use(remarkStringify)
.process(`<h1>Hi</h1>
<p><em>Hello</em>, world!</p>`)
console.log(String(file))
</script>
…opening it in a browser prints the following to the browser console:
# Hi
*Hello*, world!
API
This package exports no identifiers.
The default export is rehypeDomParse.
unified().use(rehypeDomParse[, options])
Add support for parsing from HTML with DOM APIs.
Parameters
options(Options, optional) — configuration
Returns
Transform (Transformer).
Options
Configuration (TypeScript type).
👉 Note: the default of the
fragmentoption istruein this package, which is different from the value inrehype-parse, as this makes more sense in browsers.
Fields
fragment(boolean, default:true) — specify whether to parse a fragment
Syntax
HTML is parsed and serialized according to what a browser supports (which should be WHATWG HTML).
Syntax tree
The syntax tree used in rehype is hast.
Types
This package is fully typed with TypeScript.
It exports the additional type Options.
It also registers Settings with unified.
If you’re passing options with .data('settings', …), make sure to import this
package somewhere in your types, as that registers the fields.
/**
* @import {} from 'rehype-dom-parse'
*/
import {unified} from 'unified'
// @ts-expect-error: `thisDoesNotExist` is not a valid option.
unified().data('settings', {thisDoesNotExist: false})
Compatibility
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,
rehype-dom-parse@^5, compatible with Node.js 16.
Security
Use of rehype-dom-parse is safe.
