hast utility to transform to a DOM tree.
This package is a utility that creates a DOM tree (defaulting to the actual DOM
but also supporting things like jsdom) from a hast (HTML) syntax
tree.
You can use this project when you want to turn hast into a DOM in browsers,
either to use it directly on a page, or to enable the use of DOM APIs (such as
querySelector to find things or innerHTML to serialize stuff).
The hast utility hast-util-from-dom does the inverse of
this utility.
It turns DOM trees into hast.
The rehype plugin rehype-dom-stringify wraps this
utility to serialize as HTML with DOM APIs.
This package is ESM only. In Node.js (version 16+), install with npm:
npm install hast-util-to-dom
In Deno with esm.sh:
import {toDom} from 'https://esm.sh/hast-util-to-dom@4'
In browsers with esm.sh:
<script type="module">
import {toDom} from 'https://esm.sh/hast-util-to-dom@4?bundle'
</script>
Say our page example.html looks as follows:
<!doctype html>
<title>Example</title>
<body>
<script type="module">
import {h} from 'https://esm.sh/hastscript?bundle'
import {toDom} from 'https://esm.sh/hast-util-to-dom?bundle'
const tree = h('main', [
h('h1', 'Hi'),
h('p', [h('em', 'Hello'), ', world!'])
])
document.body.append(toDom(tree))
</script>
Now running open example.html shows the main, h1, and p elements on the
page.
This package exports the identifier toDom.
There is no default export.

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-dom@^4,
compatible with Node.js 16.
Use of hast-util-to-dom can open you up to a
cross-site scripting (XSS) attack if the hast tree is unsafe.
Use hast-util-santize to make the hast tree safe.
