## ๐Ÿš€ Quick Start

### Basic HTTP/2 + HTTPS Server

```rust
use ignitia::{
    Router, Server, Response, Result, Http2Config, ServerConfig, TlsConfig,
    handler::extractor::{Path, Query, Json},
};
use serde::{Deserialize, Serialize};

#[tokio::main]
async fn main() -> Result<()> {
    // Initialize logging
    tracing_subscriber::init();

    let router = Router::new()
        .get("/", || async {
            Ok(Response::html("<h1>๐Ÿ”ฅ Welcome to Ignitia with HTTP/2!</h1>"))
        })
        .get("/users/:id", get_user)
        .post("/api/data", create_data)
        .get("/health", || async {
            Ok(Response::json(serde_json::json!({
                "status": "healthy",
                "protocol": "HTTP/2",
                "timestamp": chrono::Utc::now()
            }))?)
        });

    // Configure HTTP/2 with optimized settings
    let config = ServerConfig {
        http1_enabled: true,
        http2: Http2Config {
            enabled: true,
            enable_prior_knowledge: true, // H2C support
            max_concurrent_streams: Some(1000),
            initial_connection_window_size: Some(1024 * 1024), // 1MB
            adaptive_window: true,
            ..Default::default()
        },
        auto_protocol_detection: true,
        ..Default::default()
    };

    // HTTPS with automatic certificate (development)
    Server::new(router, "127.0.0.1:8443".parse()?)
        .with_config(config)
        .with_self_signed_cert("localhost")? // โš ๏ธ Development only!
        .ignitia()
        .await
}

async fn get_user(Path(user_id): Path<String>) -> Result<Response> {
    Ok(Response::json(serde_json::json!({
        "user_id": user_id,
        "name": "John Doe",
        "protocol": "HTTP/2"
    }))?)
}

#[derive(Deserialize, Serialize)]
struct ApiData {
    message: String,
    timestamp: chrono::DateTime<chrono::Utc>,
}

async fn create_data(Json(data): Json<ApiData>) -> Result<Response> {
    Ok(Response::json(serde_json::json!({
        "status": "created",
        "data": data,
        "received_at": chrono::Utc::now()
    }))?)
}
```

## ๐Ÿ”ฅ Core Features

### ๐ŸŒ HTTP/2 & HTTPS Support

Ignitia provides comprehensive support for modern HTTP protocols with automatic negotiation:

#### Production HTTPS Configuration
```rust
use ignitia::{Server, Router, TlsConfig, TlsVersion};

let router = Router::new()
    .get("/", || async { Ok(Response::text("Secure HTTPS with HTTP/2!")) });

// Production TLS setup
let tls_config = TlsConfig::new("production.crt", "production.key")
    .with_alpn_protocols(vec!["h2", "http/1.1"]) // HTTP/2 priority
    .tls_versions(TlsVersion::TlsV12, TlsVersion::TlsV13)
    .enable_client_cert_verification();

Server::new(router, "0.0.0.0:443".parse()?)
    .with_tls(tls_config)?
    .ignitia()
    .await
```

#### HTTP to HTTPS Redirect
```rust
// Automatic redirect from HTTP to HTTPS
Server::new(router, "0.0.0.0:80".parse()?)
    .redirect_to_https(443)
    .ignitia()
    .await
```

#### H2C (HTTP/2 Cleartext) Support
```rust
let config = ServerConfig {
    http2: Http2Config {
        enabled: true,
        enable_prior_knowledge: true, // Enables H2C

### ๐ŸŒ Advanced WebSocket Support

First-class WebSocket implementation with optimized performance:

```rust
use ignitia::{websocket_handler, websocket_message_handler, Message, WebSocketConnection};
use serde::{Deserialize, Serialize};

let router = Router::new()
    // Simple echo server
    .websocket("/ws/echo", websocket_handler(|ws: WebSocketConnection| async move {
        while let Some(message) = ws.recv().await {
            match message {
                Message::Text(text) => {
                    ws.send_text(format!("Echo: {}", text)).await?;
                }
                Message::Binary(data) => {
                    ws.send_bytes(data).await?;
                }
                Message::Close(_) => break,

    // Advanced JSON chat
    .websocket("/ws/chat", websocket_message_handler(|ws, message| async move {
        if let Message::Text(text) = message {
            #[derive(Deserialize, Serialize)]
            struct ChatMessage {
                user: String,
                message: String,

```

### ๐Ÿ›ก๏ธ Advanced CORS Configuration

Comprehensive CORS middleware with flexible origin matching:

```rust
use ignitia::{CorsMiddleware, Method};

// Development CORS (permissive)
let dev_cors = CorsMiddleware::permissive();

// Production CORS with specific origins
let prod_cors = CorsMiddleware::new()
    .allowed_origins(&["https://myapp.com", "https://api.myapp.com"])
    .allowed_methods(&[Method::GET, Method::POST, Method::PUT, Method::DELETE])
    .allowed_headers(&["Content-Type", "Authorization", "X-API-Key"])
    .expose_headers(&["X-Total-Count", "X-Rate-Limit"])
    .allow_credentials()
    .max_age(86400) // 24 hours
    .build()?;

// Regex-based origin matching
let regex_cors = CorsMiddleware::new()
    .allowed_origin_regex(r"https://.*\.myapp\.com$") // All subdomains
    .build()?;

let router = Router::new()
    .middleware(prod_cors)
    .get("/api/data", api_handler);
```

### ๐Ÿšจ Enhanced Error Handling

Comprehensive error handling with custom error types and responses:

```rust
use ignitia::{define_error, ErrorHandlerMiddleware, ErrorFormat};

// Define domain-specific errors
define_error! {
    ApiError {
        UserNotFound(StatusCode::NOT_FOUND, "user_not_found", "USER_404"),
        ValidationFailed(StatusCode::BAD_REQUEST, "validation_failed", "VALIDATION_ERROR"),
        RateLimited(StatusCode::TOO_MANY_REQUESTS, "rate_limited", "RATE_LIMIT")
    }
}

// Custom error handler middleware
let error_middleware = ErrorHandlerMiddleware::new()
    .with_details(cfg!(debug_assertions)) // Detailed errors in debug mode
    .with_json_format(ErrorFormat::Detailed)
    .with_logging(true)
    .with_error_log_threshold(500); // Log 5xx as errors, 4xx as warnings

let router = Router::new()
    .middleware(error_middleware)
    .get("/users/:id", get_user_with_validation);

async fn get_user_with_validation(Path(user_id): Path<String>) -> Result<Response> {
    if user_id.is_empty() {
        return Err(ApiError::ValidationFailed("User ID cannot be empty".into()).into());
    }

    if user_id == "404" {
        return Err(ApiError::UserNotFound(format!("User {} not found", user_id)).into());
    }

    Ok(Response::json(serde_json::json!({
        "user_id": user_id,
        "name": "John Doe"
    }))?)
}
```

## ๐Ÿ›ฃ๏ธ Advanced Routing

### Path Parameter Extraction with Types

```rust
use serde::Deserialize;

#[derive(Deserialize)]
struct UserPath {
    user_id: u32,
    post_id: String,
}

async fn get_user_post(Path(params): Path<UserPath>) -> Result<Response> {
    Ok(Response::json(serde_json::json!({
        "user_id": params.user_id,
        "post_id": params.post_id
    }))?)
}

// Supports: /users/123/posts/abc-def
let router = Router::new()
    .get("/users/:user_id/posts/:post_id", get_user_post);
```

### Wildcard Routes

```rust
// Wildcard routing for file serving
async fn serve_static(Path(path): Path<String>) -> Result<Response> {
    let safe_path = sanitize_path(&path)?;
    serve_file_from_directory("./static", &safe_path).await
}

let router = Router::new()
    .get("/static/*path", serve_static); // Matches /static/css/style.css, etc.
```

### Nested Routers

```rust
// API v1 routes
let api_v1 = Router::new()
    .get("/users", list_users)
    .post("/users", create_user)
    .get("/users/:id", get_user);

// API v2 routes
let api_v2 = Router::new()
    .get("/users", list_users_v2)
    .post("/users", create_user_v2);

// Main router with nested subrouters
let router = Router::new()
    .get("/", home)
    .nest("/api/v1", api_v1)
    .nest("/api/v2", api_v2);
```

## ๐Ÿ”ง Comprehensive Middleware

### Built-in Middleware Stack

```rust
use ignitia::{LoggerMiddleware, CorsMiddleware, AuthMiddleware, ErrorHandlerMiddleware};

let router = Router::new()
    // Request logging with HTTP version info
    .middleware(LoggerMiddleware)

    // Advanced CORS configuration
    .middleware(
        CorsMiddleware::secure_api(&["https://myapp.com"])
            .allow_credentials()
            .max_age(3600)
            .build()?
    )

    // Path-based authentication
    .middleware(
        AuthMiddleware::new("your-secret-token")
            .protect_paths(vec!["/admin", "/api/protected"])
    )

    // Enhanced error handling
    .middleware(
        ErrorHandlerMiddleware::new()
            .with_details(cfg!(debug_assertions))
            .with_logging(true)
    )

    .get("/", public_handler)
    .get("/admin", admin_handler)       // Protected
    .get("/api/protected", api_handler); // Protected
```

### Custom Middleware Implementation

```rust
use ignitia::{Middleware, Request, Response, Result};

struct RateLimitMiddleware {
    max_requests: usize,
    window_seconds: u64,
    // In production, use Redis or similar
    request_counts: Arc<Mutex<HashMap<String, (u64, std::time::Instant)>>>,
}

#[async_trait::async_trait]
impl Middleware for RateLimitMiddleware {
    async fn before(&self, req: &mut Request) -> Result<()> {
        let client_ip = req.header("x-forwarded-for")
            .or_else(|| req.header("x-real-ip"))

            .to_string();

        let mut counts = self.request_counts.lock().await;
        let now = std::time::Instant::now();

        if let Some((count, last_reset)) = counts.get_mut(&client_ip) {
            if now.duration_since(*last_reset).as_secs() > self.window_seconds {
                *count = 1;

                    return Err(ignitia::Error::BadRequest(
                        "Rate limit exceeded".into()
                    ));
                }
            }
        } else {
            counts.insert(client_ip, (1, now));
        }

        Ok(())
    }

    async fn after(&self, res: &mut Response) -> Result<()> {
        res.headers.insert(

            self.window_seconds.to_string().parse().unwrap()
        );
        Ok(())
