Simple. Fast. Web Components.

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

This is a stable release of Lit 2.0. If upgrading from previous versions of lit-element or lit-html, please see the Upgrade Guide for a step-by-step guide on upgrading.

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:

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 <span>${this.mood}</span>!`;
  }
}

Once you've defined your component, you can use it anywhere you use HTML:

<my-element mood="awesome"></my-element>
