> Scaffold a vanilla JavaScript browser extension with the Extension.js CLI, including manifest, popup, and content script wiring out of the box.

## Create the project

<CodeGroup>
  ```bash npm theme={null}
  npx extension@latest create my-extension --template=javascript
  ```

  ```bash pnpm theme={null}
  pnpx extension@latest create my-extension --template=javascript
  ```

  ```bash yarn theme={null}
  yarn dlx extension@latest create my-extension --template=javascript
  ```

  ```bash bun theme={null}
  bunx extension@latest create my-extension --template=javascript
  ```

  ```bash deno theme={null}
  deno run -A npm:extension@latest create my-extension --template=javascript
  ```
</CodeGroup>

## What you get

A clean ES modules baseline with no compile step. The template wires up `manifest.json`, popup, and content script entry points 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.
