# PostHTML <img align="right" width="220" height="200" title="PostHTML" src="http://posthtml.github.io/posthtml/logo.svg">
|
||
|
|
|
||
|
|
PostHTML is a tool for transforming HTML/XML with JS plugins. PostHTML itself is very small. It includes only a HTML parser, a HTML node tree API and a node tree stringifier.
|
||
|
|
|
||
|
|
All HTML transformations are made by plugins. And these plugins are just small plain JS functions, which receive a HTML node tree, transform it, and return a modified tree.
|
||
|
|
|
||
|
|
For more detailed information about PostHTML in general take a look at the [docs][docs-url].

|
||
|
|
**Sync**
|
||
|
|
|
||
|
|
```js
|
||
|
|
import posthtml from 'posthtml'
|
||
|
|
|
||
|
|
const html = `
|
||
|
|
<component>
|
||
|
|
<title>Super Title</title>
|
||
|
|
<text>Awesome Text</text>
|
||
|
|
</component>
|
||
|
|
`
|
||
|
|
|
||
|
|
const result = posthtml()
|
||
|
|
.use(require('posthtml-custom-elements')())
|
||
|
|
.process(html, { sync: true })
|
||
|
|
.html
|
||
|
|
|
||
|
|
console.log(result)
|
||
|
|
```
|
||
|
|
|
||
|
|
```html
|
