Simple and performant reactivity for building user interfaces written entirely in TypeScript. Solid stands on the shoulders of giants, particularly React and Knockout. If you've developed with React Hooks before, Solid should seem very natural. In fact, more natural as Solid's model is much simpler with no Hook rules. Every Component executes once and it is the Hooks and bindings that execute many times as their dependencies update. SolidJS is a vibrant community of beginners and experts alike. It takes an engineering-first approach to community.
