Backend Setup

1. Navigate to the backend folder:

   cd full-stack-expo-react-native-starter/backend 
   

2. Install dependencies:

   npm install 
   

3. Create a .env file in the backend folder and add the following environment variables:

   MONGO_URI=your_mongo_connection_string 
   private_key_id=your_private_key_id 
   client_email=your_client_email 
   client_id=your_client_id 
   auth_uri=your_auth_uri 
   token_uri=your_token_uri 
   universe_domain=your_universe_domain 
   

4. Run the server:
