email-comb

Remove unused CSS from email templates

Install

This package is ESM only: Node 12+ is needed to use it and it must be imported instead of required:

npm i email-comb

If you need a legacy version which works with require, use version 5.1.0

Quick Take

import { strict as assert } from "assert";

import { comb, defaults, version } from "email-comb";

// aptly named classes:
const source = `<head>
<style type="text/css">
.unused1[z] {a:1;}
.used[z] {a:2;}
</style>
</head>
<body class="  used  "><a class="used unused3">z</a>
</body>
`;

const intended = `<head>
<style type="text/css">
.used[z] {a:2;}
</style>
</head>
<body class="used"><a class="used">z</a>
</body>
`;

assert.equal(comb(source).result, intended);
