    "context"
    "time"
    "github.com/aminofox/zenlive/pkg/auth"
)

func main() {
    ctx := context.Background()
    store := auth.NewMemoryAPIKeyStore()
    manager := auth.NewAPIKeyManager(store)
    
    expiresIn := 365 * 24 * time.Hour
    key, _ := manager.GenerateAPIKey(ctx, "My App", &expiresIn, nil)
    
    println("API Key:", key.AccessKey)
    println("Secret:", key.SecretKey)
}
Create Room Token

Components:

  • API Server (port 7880) - HTTP REST API for room management
  • WebRTC Signaling (port 7881) - WebSocket for WebRTC negotiation
  • Room Manager - Handles video call rooms and participants
  • API Key Manager - Authentication with API key/secret pairs
  • Redis (optional) - Session management for horizontal scaling

API Endpoints

  • GET /api/health - Health check
  • POST /api/keys - Generate API key pair
  • GET /api/rooms - List rooms
  • POST /api/tokens - Generate room token (via SDK)

Comparison with LiveKit

Feature ZenLive LiveKit
WebRTC SFU ✅ ✅
API Key Auth ✅ ✅
Token-based Access ✅ ✅
Docker Deployment ✅ ✅
Redis Scaling ✅ ✅
Architecture Monorepo Separate repos
Go SDK Same repo livekit-go
JS/Mobile SDKs Planned ✅

Note: ZenLive uses a monorepo approach (server + SDK together) for faster development. Can be split into separate repos like LiveKit in the future.

Production Deployment

Security Checklist
  • Change jwt_secret in production
  • Generate unique API keys (don't use defaults)
  • Enable HTTPS/TLS for API endpoint
  • Enable WSS for WebSocket signaling
  • Configure TURN servers for NAT traversal
  • Set up firewall rules (ports 7880, 7881)
  • Enable Redis authentication
  • Use environment variables for secrets
Monitoring

Prometheus metrics at http://localhost:9090/metrics:

  • Active rooms count
  • Participant count
  • WebRTC tracks
  • API request rate

🎯 SDK Philosophy

ZenLive focuses on REAL-TIME DELIVERY - not data persistence.

✅ SDK Does:

  • Real-time streaming (RTMP, HLS, WebRTC)
  • Real-time chat delivery
  • Session management
  • Recording to local/S3

❌ SDK Does NOT:

  • Database persistence (you handle this)
  • Chat history storage (you save to your DB)
  • User account management (your responsibility)

💡 Your Responsibility: The SDK delivers real-time. YOU decide what to save to YOUR database.

📚 Documentation

💻 Examples

# Basic streaming server
cd examples/basic && go run main.go

# With authentication
cd examples/auth && go run main.go

# WebRTC video call
cd examples/webrtc && go run main.go

# With chat
cd examples/chat && go run main.go

# With recording
cd examples/storage && go run main.go

🔧 Configuration

Simple (Development)
cfg := config.DefaultConfig()
cfg.Streaming.EnableRTMP = true
cfg.Streaming.EnableHLS = true
With Chat
cfg.Chat.Enabled = true

// Save chat to YOUR database
chatServer.OnMessage(func(msg *chat.Message) {
    myDB.SaveMessage(msg) // Your code
})
Production
cfg := config.DefaultConfig()
cfg.Auth.JWTSecret = os.Getenv("JWT_SECRET")
cfg.Storage.Type = "s3"
cfg.Analytics.Enabled = true
Multi-Server (Cluster)
