API Examples

Authentication

# Register a new user
curl -X POST http://localhost:4000/api/register \
  -H "Content-Type: application/json" \
  -d '{"user": {"email": "[email protected]", "password": "password123", "username": "testuser"}}'

# Login
curl -X POST http://localhost:4000/api/login \
  -H "Content-Type: application/json" \
  -d '{"email": "[email protected]", "password": "password123", "device_id": "device123"}'

WebSocket Connection

// Connect to WebSocket
let socket = new Socket("ws://localhost:4000/socket", {
  params: { token: "your-jwt-token" },
});

socket.connect();

// Join a comment channel
let channel = socket.channel(`comments:${videoId}`, {});
channel
  .join()
  .receive("ok", (resp) => console.log("Joined successfully", resp))
  .receive("error", (resp) => console.log("Unable to join", resp));
