lit-html
Efficient, Expressive, Extensible HTML templates in JavaScript
lit-html is the template system that powers the Lit library for building fast web components.
When using lit-html to develop web components, most users should import lit-html via the lit package rather than installing and importing from lit-html directly.

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 aTemplateResult, which is a container for a template, and the values that should populate the template.render(): A function that renders aTemplateResultto a DOM container, such as an element or shadow root.
