Simple Skip the boilerplate Building on top of the Web Components standards, Lit adds just what you need to be happy and productive: reactivity, declarative templates and a handful of thoughtful features to reduce boilerplate and make your job easier. Every Lit feature is carefully designed with web platform evolution in mind.
Fast Tiny footprint, instant updates Weighing in at around 5 KB (minified and compressed), Lit helps keep your bundle size small and your loading time short. And rendering is blazing fast, because Lit touches only the dynamic parts of your UI when updating — no need to rebuild a virtual tree and diff it with the DOM.
