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';
@customElement('my-element')
export class MyElement extends LitElement {
static styles = css`
span {
color: green;
}
`;
@property()
mood = 'great';
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>
