rehype-wrap
Advanced tools
rehype-wrap
Wrap selected elements with a given element
Install
npm i -S rehype-wrap
Usage
const wrap = require('rehype-wrap')
const rehype = require('rehype')
rehype()
.use(wrap, {/* options */})
.process(/* html string */)
.then(/* vfile */)
.catch(/* handle any errors */)
Options
wrap.selector
string
Select an element to be wrapped. Expects a string selector that can be passed to hast-util-select (supported selectors). If wrap.selector is not set then wrap will check for a body element and wrap all elements inside. Otherwise, if there is no body element, wrap treats the html as a fragment and wraps everything.
wrap.wrapper
string
Element to wrap around wrap.selector. Expects a string selector that can be parsed into html using hast-util-parse-selector (see readme)
Example
# dependencies
npm i unified to-vfile remark-parse remark-rehype vfile-reporter rehype-document rehype-stringify remark-wrap
# example.md
```js
const foo = 'bar'
```
/* example.js */
'use strict'
const unified = require('unified')
const toVfile = require('to-vfile')
const remarkParse = require('remark-parse')
const remarkRehype = require('remark-rehype')
const vfileReporter = require('vfile-reporter')
const rehypeDocument = require('rehype-document')
const rehypeStringify = require('rehype-stringify')
const rehypeWrap = require('rehype-wrap')
const markdown = toVfile.readSync('./example.md')
unified()
.use(remarkParse)
.use(remarkRehype)
.use(rehypeDocument)
.use(rehypeWrap, {wrapper: 'div.markdown-body'})
.use(rehypeStringify)
.process(markdown, (err, file) => {
console.error(vfileReporter(err ||file))
console.log(String(file))
})
