:::info
All templates default to TypeScript. Rename the file extensions to `.js` to use JavaScript instead.

## From Scratch

Initialize a project and install `wxt`:

:::code-group

```sh [pnpm]
pnpm init
pnpm add -D wxt
```

```sh [npm]
npm init
npm i --save-dev wxt
```

```sh [yarn]
yarn init
yarn add --dev wxt
```

```sh [bun]
bun init
bun add --dev wxt
```

:::

Add your first entrypoint:

```ts
// entrypoints/background.ts
export default defineBackground(() => {
  console.log(`Hello from ${browser.runtime.id}!`);
});
```

And add scripts to your `package.json`:

```json
{
  "scripts": {
    "dev": "wxt", // [!code ++]
    "dev:firefox": "wxt --browser firefox", // [!code ++]
    "build": "wxt build", // [!code ++]
    "build:firefox": "wxt build --browser firefox", // [!code ++]
    "zip": "wxt zip", // [!code ++]
    "zip:firefox": "wxt zip --browser firefox", // [!code ++]
    "postinstall": "wxt prepare" // [!code ++]
  }
}
```

## Development

Once the project is setup, you can start the development server using the `dev` script.

```sh
pnpm dev
```

:::tip 🎉&ensp;Well done!

The dev command will build the extension for development, open the browser, and reload the different parts of the extension when you save changes.
