Posthtml NPM | npm.io

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.

Sync

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)

<div class="component">
  <div class="title">Super Title</div>
  <div class="text">Awesome Text</div>
</div>

: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

import posthtml from 'posthtml'

const html = `

`

posthtml(
  [
    require('posthtml-to-svg-tags')(),
    require('posthtml-extend-attrs')({
      attrsTree: {
        '.wow' : {
          id: 'wow_id',
          fill: '#4A83B4',
          'fill-rule': 'evenodd',
          'font-family': 'Verdana'
        }
      }
    })
  ])
  .process(html/*, options */)
  .then((result) =>  console.log(result.html))

<svg xmlns="http://www.w3.org/2000/svg">
