Efficient, Expressive, Extensible HTML templates in JavaScript

Build Status Published on npm Mentioned in Awesome lit-html

Documentation

Full documentation is available at polymer.github.io/lit-html.

Overview

lit-html lets you write HTML templates in JavaScript with template literals.

lit-html templates are plain JavaScript and combine the familiarity of writing HTML with the power of JavaScript. lit-html takes care of efficiently rendering templates to DOM, including efficiently updating the DOM with new values.

import {html, render} from 'lit-html';

// This is a lit-html template function. It returns a lit-html template.
const helloTemplate = (name) => html`<div>Hello ${name}!</div>`;

// This renders <div>Hello Steve!</div> to the document body
render(helloTemplate('Steve'), document.body);

// This updates to <div>Hello Kevin!</div>, but only updates the ${name} part
render(helloTemplate('Kevin'), document.body);

lit-html provides two main exports:

  • html: A JavaScript template tag used to produce a TemplateResult, which is a container for a template, and the values that should populate the template.
  • render(): A function that renders a TemplateResult to a DOM container, such as an element or shadow root.

Installation

$ npm install lit-html

Status

lit-html is under active development and has not yet had a 1.0 release. The internal API may still change somewhat. The html and render API is stable.
