# rehype [![Build Status][build-badge]][build-status] [![Coverage Status][coverage-badge]][coverage-status] [![Chat][chat-badge]][chat]
The [**rehype**][rehype] processor is an HTML processor powered by
[plug-ins][plugins].
* Interface by [**unified**][unified]
* [**hast**][hast] syntax tree
* Parses HTML to the tree with [**rehype-parse**][parse]
* [Plug-ins][plugins] transform the tree
* Compiles the tree to HTML using [**rehype-stringify**][stringify]
Don’t need the parser? Or the compiler? [That’s OK][unified-usage].
## Installation
[npm][]:
```bash
npm install rehype
```
## Usage
```js
var rehype = require('rehype');
var report = require('vfile-reporter');
rehype().process('HiHello world!', function (err, file) {
console.log(report(err || file));
console.log(String(file));
});
```
Yields:
```txt
no issues found
HiHello world!
```
Configuration for [**rehype-parse**][parse] and
[**rehype-stringify**][stringify] can be set with
`.data('settings', {/*...*/})`.
