This Val Town project provides a simple service to help a React Native mobile app discover and connect to a restaurant server running on a desktop application.

In a restaurant management system where:

• A desktop application runs the server with APIs
• A React Native mobile app needs to connect to those APIs
• The server's IP address might change

This service acts as a bridge that allows the server to register its current IP address and the mobile app to discover it.

1. Server Registration: When the desktop server starts, it sends its current IP address to this service
2. Mobile App Discovery: The mobile app queries this service to get the latest server IP address
3. Direct Connection: The mobile app then connects directly to the server using the discovered IP

POST /register
Authorization: Bearer YOUR_SECRET_TOKEN
Content-Type: application/json

{
  "ipAddress": "192.168.1.100",
  "port": 8080
}

GET /

Response:

{
  "ipAddress": "192.168.1.100",
  "port": 8080,
  "updatedAt": "2023-06-15T12:34:56.789Z"
}

• Uses Val Town's blob storage to persist the server IP address
• Includes basic token authentication for the registration endpoint
• Provides CORS headers to allow cross-origin requests from the mobile app

1. Set the SERVER_REGISTER_TOKEN environment variable in Val Town for security
2. Configure the desktop server to call the registration endpoint on startup
3. Configure the React Native app to query this service before making API calls
