You can try out lit-html without installing anything using an online editor. Below are links to a simple lit-html starter project in some popular online editors:
lit-html is written in and distributed as standard JavaScript modules. Modules are increasingly supported in JavaScript environments and have shipped in Chrome, Firefox, Edge, Safari, and Opera.
The JavaScript import statement only works inside module scripts (<script type="module">), which can be inline scripts (as shown above) or external scripts.
The path to use depends on where you've installed lit-html. Browsers only support importing other modules by path, not by package name, so without other tools involved, you'll have to use paths.
If you use a tool that converts package names into paths, then you can import by package name:
import{html,render}from'lit-html';
For simplicity, the examples in these docs use package names (also known as node-style module specifiers).
See Tools for information on build tools and dev servers you can use to convert node-style module specifiers to browser-style module specifiers.
Why JavaScript modules? For more information on why lit-html is distributed using JavaScript modules, see JavaScript Modules.
