What is this?
This is likerehype
rehype but for browsers.When should I use this?
Use this package when you want to userehype
in browsers.
There are some limitations: see the monorepo readmerehype-dom for info on
when (not) to use rehype-dom
.Install
This package is ESM onlyesm. In Node.js (version 16+), install with npm:npm install rehype-dom
In Deno with
esm.sh
esmsh:import {rehypeDom} from 'https://esm.sh/rehype-dom@7'
In browsers with
esm.sh
esmsh:<script type="module">
import {rehypeDom} from 'https://esm.sh/rehype-dom@7?bundle'
</script>
Use
Say our pageexample.html
contains:<!doctype html>
<title>Example</title>
<body>
<script type="module">
import {rehypeDom} from 'https://esm.sh/rehype-dom@7?bundle'
const file = await rehypeDom().process('<h1>Hi <del>Mars</del>Venus!</h1>')
document.body.innerHTML = String(file)
</script>
…opening it in a browser renders the following in
<body>
:<h1>Hi <del>Mars</del>Venus!</h1>
API
This package exports the identifierrehypeDom
api-rehype-dom.
There is no default export.rehypeDom()
Create a new unified processor that already uses
rehype-dom-parse
rehype-dom-parse and
rehype-dom-stringify
rehype-dom-stringify.You can add more plugins with
use
.
See unified
unified for more information.👉 Note: the default of thefragment
option istrue
in this package, which is different from the value inrehype
, because it makes more sense in browsers.
Examples
Example: passing options
When you userehype-dom-parse
or rehype-dom-stringify
manually you can pass
options directly to them with use
.
Because both plugins are already used in rehype
, that’s not possible.
To define options for them, you can instead pass options to data
:import {rehypeDom} from 'https://esm.sh/rehype-dom@7?bundle'
const file = await rehypeDom()
.data('settings', {fragment: false})
.process('<!doctype html>' + document.documentElement.outerHTML)
console.log(String(file))
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 no additional types.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./**
* @typedef {import('rehype-dom')}
*/
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@^7
, compatible with Node.js 16.Security
Use ofrehype-dom
can open you up to a cross-site scripting (XSS)xss
attack if dangerous content is used and the result is used with the actual DOM.
Use rehype-sanitize
rehype-sanitize to solve that.Contribute
