This package is a [unified][] processor with support for parsing HTML as input and serializing HTML as output by using unified with [`rehype-parse`][rehype-parse] and [`rehype-stringify`][rehype-stringify]. See [the monorepo readme][rehype] for info on what the rehype ecosystem is. ## When should I use this? You can use this package when you want to use unified, have HTML as input, and want HTML as output. This package is a shortcut for `unified().use(rehypeParse).use(rehypeStringify)`. When the input isn’t HTML (meaning you don’t need `rehype-parse`) or the output is not HTML (you don’t need `rehype-stringify`), it’s recommended to use `unified` directly. When you’re in a browser, trust your content, don’t need positional info on nodes or formatting options, and value a smaller bundle size, you can use [`rehype-dom`][rehype-dom] instead. When you want to inspect and format HTML files in a project on the command line, you can use [`rehype-cli`][rehype-cli]. ## Install This package is [ESM only][esm]. In Node.js (version 16+), install with [npm][]: ```sh npm install rehype ``` In Deno with [`esm.sh`][esmsh]: ```js import {rehype} from 'https://esm.sh/rehype@13' ``` In browsers with [`esm.sh`][esmsh]: ```html ``` ## Use Say we have the following module `example.js`: ```js import {rehype} from 'rehype' import rehypeFormat from 'rehype-format' const file = await rehype().use(rehypeFormat).process(` Hi!

Hello!

`) console.error(String(file)) ``` …running that with `node example.js` yields: ```html Hi!

Hello!

``` ## API This package exports the identifier [`rehype`][api-rehype]. There is no default export. ### `rehype()` Create a new unified processor that already uses [`rehype-parse`][rehype-parse] and [`rehype-stringify`][rehype-stringify]. You can add more plugins with `use`. See [`unified`][unified] for more information. ## Examples ### Example: passing options to `rehype-parse`, `rehype-stringify` When you use `rehype-parse` or `rehype-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`: ```js import {rehype} from 'rehype' import {reporter} from 'vfile-reporter' const file = await rehype() .data('settings', { emitParseErrors: true, fragment: true, preferUnquoted: true }) .process('

') console.error(reporter(file)) console.log(String(file)) ``` …yields: ```txt 1:21-1:21 warning Unexpected duplicate attribute duplicate-attribute hast-util-from-html ⚠ 1 warning ``` ```html

``` ## Syntax HTML is parsed and serialized according to WHATWG HTML (the living standard), which is also followed by all browsers. ## Syntax tree The syntax tree format used in rehype is [hast][]. ## Types This package is fully typed with [TypeScript][]. It exports no additional types. ## 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@^13`, compatible with Node.js 16. ## Security As **rehype** works on HTML, and improper use of HTML can open you up to a [cross-site scripting (XSS)][xss] attack, use of rehype can also be unsafe. Use [`rehype-sanitize`][rehype-sanitize] to make the tree safe. Use of rehype plugins could also open you up to other attacks. Carefully assess each plugin and the risks involved in using them.
