• GET / - Home endpoint
• POST /packet - Main packet handler for authentication and other actions
• GET /static/* - Static file serving

The application uses JWT tokens for authentication. Include the token in the Authorization header:

Authorization: <your-jwt-token> 

WebSocket server runs alongside the HTTP server and handles real-time communication.

To run the application in development mode:

go run main.go

The server will start on the port specified in your .env file.

• Gorilla Mux - HTTP router and URL matcher
• GORM - ORM library for Go
• PostgreSQL Driver - Database driver for PostgreSQL
• Socket.IO - WebSocket library
• JWT - JSON Web Token implementation
• CORS - Cross-Origin Resource Sharing middleware

• Chats.go PinnedMsg *Message gorm:"foreignKey:PinnedMsgID;references:ID"
