## Create the project

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

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

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

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

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

## What you get

The same component model as React with a 3kB runtime, configured with the standard `preact/compat` aliasing so most React libraries keep working. A good fit when bundle size matters, especially for content scripts injected into other people's pages.
