Rehype plugin to remove unused stylesheet with uncss
Installation
npm install rehype-remove-unused-cssUsage
Say example.html looks as follows;
<html>
<head>
<style>
.one {
font-size: 1em;
}
.two {
font-size: 2em;
}
</style>
</head>
<body>
<p class="one">example</p>
</body>
</html>...and example.js like this:
const vfile = require("to-vfile")
const report = require("vfile-report")
const unified = require("unified")
const rehype = require("rehype-parse")
const stringify = require("rehype-stringify")
const removeUnusedCss = require("rehype-remove-unused-css")
unified()
.use(rehype)
.use(removeUnusedCss)
.use(stringify)
.processSync(vfile.readSync("example.html"), (err, file) => {
console.error(report(err || file))
console.log(String(file))
})Now, running node example yields:
<html>
<head>
<style>
.one {
font-size: 1em;
}
</style>
</head>
<body>
<p class="one">example</p>
</body>
