lit-html support inside "*.ts" #239

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

// A lit-html template uses the `html` template tag:
let sayHello = (name) => html`<h1>Hello ${name}</h1>`;

// It's rendered with the `render()` function:
render(sayHello('World'), document.body);

// And re-renders only update the data that changed, without VDOM diffing!
render(sayHello('Everyone'), document.body);
