Fast. Web Components. [](https://github.com/lit/lit/actions/workflows/tests.yml) [](https://www.npmjs.com/package/lit) [](https://lit.dev/discord/) [](https://github.com/web-padawan/awesome-lit) </div> Lit is a simple library for building fast, lightweight web components. At Lit's core is a boilerplate-killing component base class that provides reactive state, scoped styles, and a declarative template system that's tiny, fast and expressive. ### Documentation See the full documentation for Lit at [lit.dev](https://lit.dev). Additional documentation for developers looking to contribute or understand more about the project can be found in [`dev-docs`](./dev-docs). ### npm To install from npm: ```sh npm i lit ``` ## Lit Monorepo This is the monorepo for Lit packages. lit 2.x source is available on the [`2.x`](https://github.com/lit/lit/tree/2.x) branch. lit-html 1.x source is available on the [`lit-html-1.x`](https://github.com/lit/lit/tree/lit-html-1.x) branch. ### Packages - Core packages - [`lit`](./packages/lit) - The primary user-facing package of Lit which includes everything from lit-html and lit-element. - [`lit-element`](./packages/lit-element) - The web component base class used in Lit. - [`lit-html`](./packages/lit-html) - The rendering library used by LitElement. - [`@lit/reactive-element`](./packages/reactive-element) - A low level base class that provides a reactive lifecycle based on attribute/property changes. - Additional libraries - [`@lit/localize`](./packages/localize) - A library and command-line tool for localizing web applications built using Lit. - [`@lit/localize-tools`](./packages/localize-tools) - Localization tooling for use with `@lit/localize`. - [`@lit/react`](./packages/react) - A React component wrapper for web components. - [`@lit/task`](./packages/task) - A controller for Lit that renders asynchronous tasks. - [`@lit/context`](./packages/context) - A system for passing data through a tree of elements using browser events, avoiding the need to pass properties down every layer of the tree using [a community defined protocol](https://github.com/webcomponents-cg/community-protocols/blob/main/proposals/context.md). - Labs - [`@lit-labs/ssr`](./packages/labs/ssr) - A server package for rendering Lit templates and components on the server. - [`@lit-labs/ssr-client`](./packages/labs/ssr-client) - A set of client-side support modules for rendering Lit components and templates on the server using `@lit-labs/ssr`. - [`@lit-labs/eleventy-plugin-lit`](./packages/labs/eleventy-plugin-lit) - A plugin for Eleventy that pre-renders Lit components using `@lit-labs/ssr` with optional hydration. - [`@lit-labs/ssr-react`](./packages/labs/ssr-react) - A package for integrating Lit SSR with React and React frameworks. - [`@lit-labs/nextjs`](./packages/labs/nextjs) - A plugin for [Next.js](https://nextjs.org/) that enables deep server rendering of Lit components with Lit SSR. - [`@lit-labs/router`](./packages/labs/router) - A router for Lit. - [`@lit-labs/motion`](./packages/labs/motion) - Lit directives for making things move - [`@lit-labs/scoped-registry-mixin`](./packages/labs/scoped-registry-mixin) - A mixin for LitElement that integrates with the speculative Scoped CustomElementRegistry polyfill. - [`@lit-labs/observers`](./packages/labs/observers) - A set of reactive controllers that facilitate using the platform observer objects. - [`@lit-labs/preact-signals`](./packages/labs/preact-signals) - [Preact Signals](https://preactjs.com/guide/v10/signals/) integration for Lit. - [`@lit-labs/signals`](./packages/labs/signals) - [TC39 proposal Signals](https://github.com/tc39/proposal-signals) integration for Lit. - [`@lit-labs/testing`](./packages/labs/testing) - Utilities for testing Lit components. - [`@lit-labs/virtualizer`](./packages/labs/virtualizer) - Viewport-based virtualization (including virtual scrolling). - [`@lit-labs/compiler`](./packages/labs/compiler) - A compiler for optimizing Lit templates. - Starter kits (not published to npm) - [`lit-starter-ts`](./packages/lit-starter-ts) ([template repo](https://github.com/lit/lit-element-starter-ts)) - A starter repo for building reusable components using Lit in TypeScript. - [`lit-starter-js`](./packages/lit-starter-js) ([template repo](https://github.com/lit/lit-element-starter-js)) - A starter repo for building reusable components using Lit in JavaScript. - Internal packages (not published to npm) - [`tests`](./packages/tests) - Test infrastructure for the monorepo. - [`benchmarks`](./packages/benchmarks) - Benchmarks for testing various libraries in the monorepo. - [`@lit-internal/scripts`](./packages/@lit-internal/scripts) - Utility scripts used within the monorepo. ## Contributing to Lit Lit is open source and we appreciate issue reports and pull requests.
