Welcome to this user-friendly guide on Classix, the ultimate tool for conditionally joining class names swiftly and easily! This utility, designed with simplicity at its core, enables developers to craft responsive and dynamic styles for their web applications. Below, we’ll walk you through the installation process, usage examples, comparisons to other libraries, and troubleshooting tips to ensure you get the most out of Classix.
Installation
To get started with Classix, install it via npm. Simply run the following command in your terminal:
bash
npm install classix
Usage
Classix allows you to use any number of string expressions to join your class names effortlessly. Here are some examples:
- Basic Usage:
import cx from 'classix';Usage:
cx('class1', 'class2');yields'class1 class2' - Combining Multiple Classes:
For multiple class names:
cx('class1 class2', 'class3', 'class4 class5');results in'class1 class2 class3 class4 class5' - Conditional Classes:
Using conditions:
cx('class1', true && 'class2');evaluates to'class1 class2', whilecx(false && 'class1', 'class2');results in'class2' - Using Ternary Operators:
Implementing conditions with ternary operators like:
cx('class1', true ? 'class2' : 'class3');provides'class1'
In essence, Classix invokes an expressive way to handle class names that is both concise and readable.
Comparison with Other Libraries
Unlike its competitors, Classix allows string expressions as arguments. Think of it this way: using Classix is like crafting a dish with only the freshest ingredients where you have complete control over the flavors. Here’s how it stacks against others:
js
// With clsx
clsx({ 'class-1': isPrimary });
// With classix
cx(isPrimary && 'class-1');
Benefits of using Classix:
- A faster typing experience
- A more intuitive syntax (conditions evaluated first)
- Eliminates unnecessary object notation, leading to a smaller library size and better performance
Size and Performance
Classix stands out not just for its speed but also for its small footprint. Check out the size comparison chart:

Performance benchmarks reveal that Classix performs excellently, even on slower machines!

Highlights
- Supports all major browsers
- Compatible with all versions of Node.js
- Functions seamlessly with ES Modules and CommonJS
- No dependencies required
- Fully typed with TypeScript and rigorously tested
- Follows [Semver](https://semver.org) standards
Migrating to Classix
If you are transitioning from libraries like classnames or clsx, simply change your import statement:
diff
-import classnames from 'classnames';
+import cx from 'classix';
For those using object arguments, convert them to string arguments like this:
diff
-classnames({ 'class-1': cond1, 'class-2': cond2 });
+cx(cond1 && 'class-1', cond2 && 'class-2');
Troubleshooting
If you encounter issues while using Classix, here are some troubleshooting tips:
- Ensure you have imported Classix correctly:
import cx from 'classix';. - Double-check your class name conditions—make sure they are returning the expected Boolean values.
- Look out for typos in class names as they can lead to unexpected results.
