Lit is a small (~5 KB) TypeScript library for building fast, lightweight web components on top of browser standards. It provides a reactive base class, scoped styles, and an efficient declarative HTML template system (lit-html) that only updates dynamic DOM parts.
Use cases
- build reusable web components
- create a design system usable across frameworks
- build a fast lightweight single-page app without a heavy framework
- progressively enhance server-rendered or CMS-driven HTML pages
- share components between React, Vue, and plain HTML apps
- add interactivity to static sites built with Jekyll or eleventy
When to choose
- you want framework-agnostic components that work anywhere HTML works
- bundle size and rendering performance are priorities
- you're building a shareable component library or design system
- you want minimal lock-in and easy incremental migration
When to avoid
- you need a large ecosystem with batteries-included routing, state, and data layers
- your team is already deeply invested in React or Vue conventions
- you need mature SSR out of the box (Lit SSR is still in labs)
- you require extensive mobile-native support
