What is this?

This package is a unified (rehype) plugin that can turn HTML into JavaScript.

When should I use this?

Use this when you want to integrate static HTML into some JavaScript application.

If you don’t use plugins and access syntax trees manually, you can directly use hast-util-to-estree, which is used inside this plugin.

Install

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

npm install rehype-recma

In Deno with esm.sh:

import rehypeRecma from 'https://esm.sh/rehype-recma@1'

In browsers with esm.sh:

<script type="module">
  import rehypeRecma from 'https://esm.sh/rehype-recma@1?bundle'
</script>

Use

Say we have the following module example.js:

import recmaJsx from 'recma-jsx'
import recmaStringify from 'recma-stringify'
import rehypeParse from 'rehype-parse'
import rehypeRecma from 'rehype-recma'
import {unified} from 'unified'

const file = await unified()
  .use(rehypeParse, {fragment: true})
  .use(rehypeRecma)
  .use(recmaJsx)
  .use(recmaStringify)
  .process('<p>Hi!<h1>Hello!')

console.log(String(file))

…running that with node example.js yields:

<><p>{"Hi!"}</p><h1>{"Hello!"}</h1></>;

API

This package exports no identifiers. The default export is rehypeRecma.

unified().use(rehypeRecma[, options])

Plugin to transform HTML (hast) to JS (estree).

Parameters

• options (Options, optional) — configuration

Returns

Transform (Transformer).

Options

Configuration (TypeScript type).

Same as Options from hast-util-to-estree.

Types

This package is fully typed with TypeScript. It exports the additional type Options.

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-recma@1, compatible with Node.js 16.

Security

As recma works on JS and evaluating JS is unsafe, use of recma can also be unsafe. Do not evaluate unsafe code.
