classtrate

A small utility for stripping unwanted classes from HTML strings ✂️

When do you need this?

Working with genereated HTML can be a pain; you don't always have control of the output and when you need to use that markup somewhere else you often have to perform some clean up first. This library allows you to filter specific vendor generated classes (or IDs) to make working with HTML strings easier. Some possible use cases:

• Reducing document size prior to HTML minification
• Preventing class collisions and other conflicts
• Cleaning output for user operations like copying and pasting

Minimum Requirements

This library makes use of String.prototype.replaceAll() so support for ES2021 or higher is required.

See Caniuse

# Using npm
npm install classtrate

import { filter } from 'classtrate'; // require() also supported

const source = '<h1 class="br-fGy7jw my-class">My Heading</h1>'; // String of janky HTML

const output = filter(source, pattern); // <h1 class="my-class">My Heading</h1>
