Deployment > Deploy your backend to the Railway. First, you need to create a new project on Railway. Click to navigate to Railway and create a new account. Authorize Railway to access your GitHub repository. Click the "New" button. Firebase

Click the "Deploy from Github Repo" button. Firebase

Pick the repository you want to deploy. Firebase

After you pick the repository, you need to abort the deployment. Because we need to import our `.env` variables into the Railway project. Firebase

Now, click the Variables section and then click the "Raw Editor" button. Firebase

Copy the `.env` variables from the `[your-app-name]-backend/.env.production` file and paste it into the Railway project. Then click Update Variables. Firebase

As you can see, the variables are imported successfully. But not done yet. Firebase

Now click the "New Variable" button. Firebase

Name should be `FIREBASE_SERVICE_ACCOUNT` and the value should be the content of the `[your-app-name]-backend/firebase-service-account.json` file. Click the Add button.

Now, we are ready to deploy the backend. Firebase

After successfully deploying the backend, go to the settings section and click the "Generate Domain" button. Firebase

After generating the domain, you can add it to the Expo environment variables. (Especially for the .env.production file) You can run it with ngrok or localhost on dev mode. Copy the domain and paste it into the `.env.production` file. Firebase

When you want to publish your app, it is okey to go with that. But in development, you don't need to deploy the backend. Firebase

Open Expo App and try something. (I have all API keys so I can try everything) As you can see, our request is successfully sent to the backend. Firebase

Some of the results are shown below. Firebase
