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. ## About this release Lit 3.0 has very few breaking changes from Lit 2.0: - Drops support for IE11 - Published as ES2021 - Removes a couple of deprecated Lit 1.x APIs Lit 3.0 should require no changes to upgrade from Lit 2.0 for the vast majority of users. Most apps and libraries will be able to extend their npm version ranges to include both 2.x and 3.x, like `"^2.7.0 || ^3.0.0"`. Lit 2.x and 3.0 are _interoperable_: templates, base classes, directives, decorators, etc., from one version of Lit will work with those from another. Please file any issues you find on our [issue tracker](https://github.com/lit/lit/issues). ## Documentation See the full documentation for Lit at [lit.dev](https://lit.dev) ## Overview Lit provides developers with just the right tools to build fast web components: - A fast declarative HTML template system - Reactive property declarations - A customizable reactive update lifecycle - Easy to use scoped CSS styling Lit builds on top of standard web components, and makes them easier to write: ```ts import {LitElement, html, css} from 'lit'; import {customElement, property} from 'lit/decorators.js'; // Registers the element @customElement('my-element') export class MyElement extends LitElement { // Styles are applied to the shadow root and scoped to this element static styles = css` span { color: green; } `; // Creates a reactive property that triggers rendering @property() mood = 'great'; // Render the component's DOM by returning a Lit template render() { return html`Web Components are ${this.mood}!`; } } ``` Once you've defined your component, you can use it anywhere you use HTML: ```html ``` ## Contributing Please see [CONTRIBUTING.md](../../CONTRIBUTING.md).
