# PostHTML 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](https://github.com/posthtml/posthtml/tree/master/docs). ### Dependencies | Name | Description | |:----:|:-----------:| |[posthtml-parser](https://github.com/posthtml/posthtml-parser)| Parser HTML/XML to PostHTMLTree | |[posthtml-render](https://github.com/posthtml/posthtml-render)| Render PostHTMLTree to HTML/XML | ## Create to your project ```bash npm init posthtml ``` ## Install ```bash npm i -D posthtml ``` ## Usage ### API **Sync** ```js import posthtml from 'posthtml' const html = ` Super Title Awesome Text ` const result = posthtml() .use(require('posthtml-custom-elements')()) .process(html, { sync: true }) .html console.log(result) ``` ```html ``` > :warning: Async Plugins can't be used in sync mode and will throw an Error. It's recommended to use PostHTML asynchronously whenever possible. **Async** ```js import posthtml from 'posthtml' const html = `
