class-order v0.0.5

class-order

class-order is a JavaScript library that provides a unique approach to CSS class precedence, allowing HTML developers to control class precedence based on the order of classes within the class attribute. This library is designed to offer an alternative to the traditional method where CSS rules defined later in the source override earlier rules.

Installation

You can install the library using npm:

npm install class-order

Usage

React

In React applications, you can use the merge function from the class-order library to control class precedence. Here's an example of how to use it:

import { merge } from 'class-order';

// ...

<div className={merge("classA classB ...")} /* other props */>
  {/* Your component content */}
</div>

merge takes a space-separated list of class names and arranges them in the order they appear within the class attribute.

Svelte

For Svelte applications, you can use the classOrder directive provided by the class-order library. Here's an example of how to use it:

<script>
  import { classOrder } from 'class-order';
</script>

<div use:classOrder class="classA classB ..." /* other props */>
  <!-- Your component content -->
</div>

classOrder ensures that classes are applied in the order they appear within the class attribute.

You can also import from class-order/tailwind-merge if you just want to have a directive for this battle tested library.

Why Use class-order?

• Fine-grained Control: With class-order, you can explicitly determine class precedence by the order of classes in the class attribute.

• Drop-in Replacement: The library is designed to be a seamless replacement for twMerge in Tailwind CSS setups and can be easily integrated into existing projects. For a detailed comparison between class-order and tailwind-merge, check out vs_twMerge.md.

Experimental Features

You can import forceMergeor forceClassOrderrespectively if you want to completely enforce class precedence in your classattribute – this will also override !important properties, so your layout might break in multiple ways.
