<Note>
  The Remix development server (`remix dev`) relies on Node.js APIs that Bun does not implement. This guide uses Bun to
  initialize the project and install dependencies, and Node.js to run the dev server.
</Note>

***

Initialize a Remix app with `create-remix`.

```sh terminal icon="terminal"
bun create remix
```

```txt
 remix   v1.19.3 💿 Let's build a better website...

   dir   Where should we create your new project?
         ./my-app

      ◼  Using basic template See https://remix.run/docs/en/main/guides/templates#templates for more
      ✔  Template copied

   git   Initialize a new git repository?
         Yes

  deps   Install dependencies with bun?
         Yes

      ✔  Dependencies installed
      ✔  Git initialized

  done   That's it!
         Enter your project directory using cd ./my-app
         Check out README.md for development and deploy instructions.
```

***

To start the dev server, run `bun run dev` from the project root. This runs the `remix dev` command with Node.js.

```sh terminal icon="terminal"
cd my-app
bun run dev
```

```txt
$ remix dev

💿  remix dev

info  building...
info  built (263ms)
Remix App Server started at http://localhost:3000 (http://172.20.0.143:3000)
```

***

Open [http://localhost:3000](http://localhost:3000) to see the app. Changes you make to `app/routes/_index.tsx` are hot-reloaded in the browser.

***

To build your app, run `bun run build`.

```sh terminal icon="terminal"
bun run build
```

```txt
$ remix build
info  building... (NODE_ENV=production)
info  built (158ms)
```

Then start the app from the project root.

```sh terminal icon="terminal"
bun start
```

```txt
$ remix-serve ./build/index.js
[remix-serve] http://localhost:3000 (http://192.168.86.237:3000)
