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)
