> Deploy Nitro apps to DigitalOcean.

**Preset:** `digital_ocean`

<read-more></read-more>

## Set up application

1. Create a new Digital Ocean app following the [guide](https://docs.digitalocean.com/products/app-platform/how-to/create-apps/).

2. Next, you'll need to configure environment variables. In your app settings, ensure the following app-level environment variables are set:

  ```bash
  NITRO_PRESET=digital_ocean
  ```

  [More information](https://docs.digitalocean.com/products/app-platform/how-to/use-environment-variables/).

3. You will need to ensure you set an `engines.node` field in your app's `package.json` to ensure Digital Ocean uses a supported version of Node.js:

  ```json
  {
     "engines": {
        "node": "20.x"
     }
  }
  ```

  [See more information](https://docs.digitalocean.com/products/app-platform/languages-frameworks/nodejs/#node-version).

4. You'll also need to add a run command so Digital Ocean knows what command to run after a build. You can do so by adding a start script to your `package.json`:

  ```json
  {
     "scripts": {
        "start": "node .output/server/index.mjs"
     }
  }
  ```

5. Finally, you'll need to add this start script to your Digital Ocean app's run command. Go to `Components > Settings > Commands`, click "Edit", then add `npm run start`


Your app should be live at a Digital Ocean generated URL and you can now follow [the rest of the Digital Ocean deployment guide](https://docs.digitalocean.com/products/app-platform/how-to/manage-deployments/).
