ChimeCast

ChimeCast is a robust backend solution for a Zoom-like video calling application, crafted in Go. Utilizing the mux router, Gorilla WebSocket, and pion/webrtc, this backend offers seamless real-time communication through peer-to-peer (P2P) video calls. With features like simple session-based authentication and user management, ChimeCast is designed to provide a reliable foundation for high-quality video conferencing experiences.

Features

• Session-based Authentication: Custom session tokens for secure access without OAuth.
• User Management: Register, login, and manage user data.
• Real-time Communication: WebSocket-based signaling for WebRTC connections.
• Peer-to-Peer Video/Audio: WebRTC support for high-quality media streaming.
• SQLite Database: Persistent storage for user data and session logs.

Tech Stack

• Language: Go
• Framework: mux for routing and API handling
• Database: SQLite via GORM (ORM for Go)
• Real-Time Communication:
  • WebSocket: Gorilla WebSocket for signaling
  • WebRTC: pion/webrtc for P2P media streaming

API Endpoints

1. Authentication

• POST /register
  Registers a new user.

{
  "username": "example",
  "password": "password123"
}

• POST /login
  Logs in a user and returns a session token.

    {
      "username": "example",
      "password": "password123"
    }

• POST /logout
  Ends a user session (requires session token).

2. Video Call Management

• POST /call/start
  Initiates a call session with a target user. Requires authentication.

• POST /call/end
  Ends an ongoing call.

3. WebSocket Connection (for signaling)

-/ws
Establishes a WebSocket connection for WebRTC signaling between peers.
