SDK Usage

Generate API Keys

package main

import (
    "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

package main

import (
    "time"
    "github.com/aminofox/zenlive/pkg/auth"
)

func main() {
    apiKey := "your-api-key"
    secretKey := "your-secret-key"
    
    token, _ := auth.NewAccessTokenBuilder(apiKey, secretKey).
        SetIdentity("user123").
        SetName("John Doe").
        SetRoomJoin("my-room").
        SetCanPublish(true).
        SetCanSubscribe(true).
        SetValidFor(24 * time.Hour).
        Build()
    
    println("Room Token:", token)
}

Join Room

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

• Architecture - Understand how ZenLive works
• Examples - 11+ working code examples
• API Reference - Complete API docs

💻 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

See examples/ for all 11+ examples.

🔧 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)

cfg.Cluster.Enabled = true
cfg.Redis.Enabled = true // Required for cluster
