A tiny (239B) JavaScript utility for conditionally constructing CSS className strings from strings, objects, and arrays. It serves as a faster and smaller drop-in replacement for the classnames module.
Use cases
- conditionally combine css class names in react
- build className strings from objects and arrays
- replace classnames with a smaller faster alternative
- toggle tailwind classes conditionally
- join css classes while filtering falsey values
When to choose
- you need a minimal, dependency-free classname builder for any frontend framework
- you want a drop-in classnames replacement with better performance and size
- you only need string concatenation and can use the 140-byte lite build
When to avoid
- you need CSS-in-JS or style object handling rather than class name strings
- you rely on classnames plugins or features clsx does not implement
