JavaScript browser extension template - Extension.js

JavaScript template preview

Create the project

npx extension@latest create my-extension --template=javascript

pnpx extension@latest create my-extension --template=javascript

yarn dlx extension@latest create my-extension --template=javascript

bunx extension@latest create my-extension --template=javascript

deno run -A npm:extension@latest create my-extension --template=javascript

What you get

A clean ES modules baseline with no compile step. The template wires up manifest.json, a sidebar panel, a background script, and a content script entry point so you can run extension dev and start iterating immediately. Choose this template when you want the smallest possible setup, or when you plan to add tooling later only as needed.
