Introducing StyleX
· 7 min read
We are thrilled to introduce StyleX. StyleX is an expressive, deterministic, reliable, and scalable styling system for ambitious applications. We've taken the best ideas from the styling libraries that have come before to create something that is simultaneously familiar and uniquely new.
What is StyleX?
StyleX takes the developer experience of CSS-in-JS libraries and uses compile-time tooling to bridge it with the performance and scalability of static CSS. However, StyleX is not just another compiler-based CSS-in-JS library. StyleX has been carefully designed to meet the requirements of large applications, reusable component libraries, and statically typed codebases.
- StyleX supports an expressive subset of CSS. It avoids complex selectors and guarantees no specificity conflicts in the generated CSS.
- StyleX transforms, organizes, and optimizes styles into "atomic" CSS class names. There's no need to learn or manage a separate library of utility class names.
- StyleX allows styles to be merged across file and component boundaries, making it ideal for component libraries that allow user customization.
- StyleX is fully typed and provides type utilities to allow fine-grained control over what properties and values can be accepted by a component.
