Linaria
Linaria is a zero-runtime CSS-in-JS library that extracts CSS styles to separate files at build time, allowing developers to write CSS directly in JavaScript files using tagged template literals. It compiles styles into static CSS during the build process, eliminating the runtime overhead typically associated with CSS-in-JS solutions. This approach provides the developer experience of CSS-in-JS with the performance benefits of traditional CSS.
Developers should use Linaria when building performance-critical web applications where runtime CSS-in-JS overhead is a concern, such as in large-scale React or Vue projects. It's ideal for teams wanting the component-scoped styling and dynamic capabilities of CSS-in-JS while maintaining fast load times and minimal JavaScript bundle sizes. Use cases include static site generation, server-side rendering applications, and projects where CSS extraction for caching and CDN delivery is important.
