🚀 Quick Start

Real RPC WebSocket Connection ✅ FUNCTIONAL

use leptos_ws_pro::*;
use tokio::sync::mpsc;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Create message channel for WebSocket communication
    let (message_sender, _message_receiver) = mpsc::unbounded_channel();

    // Create RPC client with real WebSocket integration
    let codec = JsonCodec::new();
    let rpc_client = RpcClient::new(message_sender, codec);

    // Send real RPC message over WebSocket
    let message = SendMessageParams {
        message: "Hello, World!".to_string(),
        channel: Some("general".to_string()),
        content: Some("Hello, World!".to_string()),
        room_id: Some("room1".to_string()),
    };

    // This now sends actual WebSocket messages!
    let response = rpc_client.call("send_message", message, RpcMethod::Call).await?;
    println!("RPC Response: {:?}", response);

    Ok(())
}

Adaptive Transport

use leptos_ws_pro::transport::adaptive::AdaptiveTransport;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let mut transport = AdaptiveTransport::new();

    // Automatically selects the best available transport
    transport.connect_with_fallback("wss://api.example.com").await?;

    // Check which transport was selected
    println!("Selected transport: {}", transport.selected_transport());

    Ok(())
}

Security Features ✅ ACTIVE

use leptos_ws_pro::security::*;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Create security manager with all features active
    let security_config = SecurityConfig::default();
    let security_manager = SecurityManager::new(security_config);
    let security_middleware = SecurityMiddleware::new(security_manager);

    // Rate limiting - now actively protecting
    let mut rate_limiter = RateLimiter::new(100, 10); // 100 req/min, burst 10
    rate_limiter.check_request("client_123")?;

    // Input validation - actively validating all messages
    let validator = InputValidator::new(1024 * 1024); // 1MB max
    validator.validate_string("safe input".to_string())?;

    // Threat detection - actively analyzing requests
    let threat_detector = ThreatDetector::new();
    let is_threat = threat_detector.is_threat("suspicious content".to_string());

    // Security middleware validates all incoming messages
    let message = Message {
        data: b"test message".to_vec(),
        message_type: MessageType::Text,
    };
    security_middleware.validate_incoming_message(&message, "client_123", None).await?;

    Ok(())
}

Performance Optimizations ✅ ENABLED

use leptos_ws_pro::performance::*;

    // Create performance components
    let pool_config = ConnectionPoolConfig::default();
    let connection_pool = ConnectionPool::new(pool_config).await?;

    let message_batcher = MessageBatcher::new(100, Duration::from_millis(10));
    let message_cache = MessageCache::new(1000, Duration::from_secs(300));
    let performance_config = PerformanceConfig::default();
    let performance_manager = PerformanceManager::new(performance_config);

    // Create performance middleware
    let performance_middleware = PerformanceMiddleware::new(
        connection_pool,
        message_batcher,
        message_cache,
        performance_manager,
    );

    // Get pooled connection for better performance
    let connection = performance_middleware.get_pooled_connection("ws://localhost:8080").await?;

    // Batch messages for improved throughput
    let message = Message {
        data: b"optimized message".to_vec(),
        message_type: MessageType::Text,
    };
    performance_middleware.batch_message(message).await?;
