LitElement TypeScript starter

This directory includes a sample component project using LitElement with TypeScript

This sample uses the TypeScript compiler (tsc) to produce JavaScript that runs in modern browsers.

This sample uses ES dev server for previewing the project without a build step. ES dev server handles resolving Node-style import specifiers, which aren't supported in browsers. It also automatically transpiles code and adds polyfills to support older browsers.

Setup

Install dependencies:

npm -i

Build

To build JavaScript version of your component:

npm run build

To watch files and rebuild when the files are modified, run the following command in a separate window:

npm run build:watch

Preview

Run the dev server and open the project in a new browser tab:

npm start
