rehype-urls

Rehype plugin to rewrite URLs of href and src attributes.

Installation

``sh
npm install rehype-urls
`

Usage

Given this markup:

`html




page
link



`

You can use the following script:

`js
var rehype = require('rehype')
var urls = require('rehype-urls')

rehype()
.use(urls, removeBaseUrl)
.process(input, handleOutput)

function removeBaseUrl (url) {
if (url.host === 'internal.site') {
return url.path
}
}
`

Which will transform it into:

`html




page
link



`

You can also pass in an object:

`js
rehype()
.use(urls, { transform: removeBaseUrl })
.process(input, handleOutput)
`

It's also possible to mutate the URL nodes directly. This example will add target="_blank" to any external links:

`js
var rehype = require('rehype')
var urls = require('rehype-urls')

rehype()
.use(urls, blankExternal)
.process(input, handleOutput)

function blankExternal (url, node) {
if (url.host !== 'internal.site') {
node.properties.target = '_blank'
}
}
``
