## Create the project

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

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

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

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

  ```bash bun theme={null}
  bunx extension@latest create my-extension --template=typescript
  ```
</CodeGroup>

## What you get

Static types across popup, content, and background scripts, with `chrome` and `browser` API typings configured. Catch manifest, messaging, and permission bugs at compile time instead of in the browser console.

A solid choice for teams that want strong refactor confidence as the extension grows.
