griffel

Griffel is a CSS-in-JS library for React developers that compiles styles at build time rather than runtime, eliminating runtime overhead for improved performance. It targets teams building large-scale applications who need the developer experience of CSS-in-JS without the performance cost of dynamic style injection. Its ahead-of-time compilation makes it interesting as it combines the scoping and co-location benefits of CSS-in-JS with the zero-runtime efficiency of static CSS.
