[Ansonhkg]

What

An example to write Lit Action code in Typescript and bundling them using esBuild. You will also get Type definition for the Lit Action global variables, such as Lit.Actions and Lit.Auth.

---

Getting started

npm install

Start writing your Lit Action like a regular TS

• See demo in ./src/lit-actions/hello-world.ts

To build and bundle the TS Lit Action code

npm run build

This will build and bundle all files in ./src/lit-actions/*.ts, and the output will be in ./src/lit-actions/dist.

Getting the bundled Lit Action Code

In your ./src/index.ts file, you can import the bundled Lit Action code like this:

import { code } from "./lit-actions/dist/hello-world.js";

console.log("litActionCode:", code);

output

npm run build

> lit-actions-ts-bundling@1.0.0 build
> node esbuild.config.js
