Lit

Lit is a simple library for building fast and lightweight web components. It builds directly on top of the Web Components standards, adding just what you need to be productive: reactivity, declarative templates, and a handful of features to reduce boilerplate code.

With a tiny ~5 KB footprint (minified and compressed), Lit ensures your bundle size remains small and loading times are short. Its rendering is exceptionally fast because it updates only the dynamic parts of your UI directly, without the overhead of a virtual DOM.

Since every Lit component is a native web component, they are interoperable and future-ready. They work anywhere you use HTML, with any framework, or none at all. This makes Lit an excellent choice for building:

• Shareable components that can be dropped into any site.
• Design systems that serve teams using multiple tech stacks.
• Maintainable, future-ready sites and applications.
