```

6. Run Your First Server

Test your setup with a simple Hello, World! server:

use axum::{handler::get, Router};

#[tokio::main]
async fn main() {
    let app = Router::new().route("/", get(|| async { "Hello, World!" }));
    axum::Server::bind(&([127, 0, 0, 1], 3000).into())
        .serve(app.into_make_service())
        .await
        .unwrap();
}

Start the server:

cargo run

Visit http://127.0.0.1:3000 in your browser, and you’re ready to go! 🎉

Safety Rust’s memory safety guarantees ensure fewer bugs and vulnerabilities compared to languages like C++ or PHP.
Concurrency With its async runtime and modern concurrency model, Rust is well-suited for handling multiple simultaneous connections.
Rich Ecosystem Tools like axum, warp, and actix-web make web development simple and expressive.
Cross-platform Deployments Rust's portability allows seamless deployment across different platforms and environments.

🚀 Setting Up a Rust Web Server

We’ll use the axum framework to build our server. It’s lightweight, async-native, and easy to use for both beginners and experts.

Step 1: Create a New Rust Project

Start by creating a new Rust project:

$ cargo new rust-web-server
$ cd rust-web-server

Step 2: Add Dependencies

Add the following dependencies to your Cargo.toml:

[dependencies]
axum = "0.6"
tokio = { version = "1", features = ["full"] }
serde = { version = "1.0", features = ["derive"] }
serde_json = "1.0"
tower = "0.4"

Step 3: Write Your First Web Server

use axum::{routing::get, Router};
use std::net::SocketAddr;

#[tokio::main]
async fn main() {
    // Define a basic route
    let app = Router::new().route("/", get(|| async { "Hello, Rustacean!" }));

    // Bind to an address and start the server
    let addr = SocketAddr::from(([127, 0, 0, 1], 3000));
    println!("Server running at http://{}", addr);

    axum::Server::bind(&addr)
        .serve(app.into_make_service())
        .await
        .unwrap();
}

Run the server with:

$ cargo run

Visit http://127.0.0.1:3000 in your browser. You’ll see Hello, Rustacean!.

⚙ Basic Web Server with `axum`

Here’s a minimal example:

use axum::{routing::get, Router};
use std::net::SocketAddr;

#[tokio::main]
async fn main() {
    // Define a basic route
    let app = Router::new().route("/", get(|| async { "Hello, World!" }));

    // Bind to an address and start the server
    let addr = SocketAddr::from(([127, 0, 0, 1], 3000));
    println!("Server running at http://{}", addr);
    axum::Server::bind(&addr)
        .serve(app.into_make_service())
        .await
        .unwrap();
}

Run the server with:

$ cargo run

Visit http://127.0.0.1:3000 to see Hello, World!.

🔧 Adding Routes

Define additional routes for different endpoints:

let app = Router::new()
    .route("/", get(|| async { "Welcome to Rust Web Development!" }))
    .route("/hello", get(|| async { "Hello, Rustacean!" }))
    .route("/json", get(|| async { axum::Json(serde_json::json!({"message": "Hello, JSON!"})) }));

🛠 Handling Requests and Responses

Use axum’s request extractors to handle data:

use axum::{extract::Query, routing::get, Router};
use serde::Deserialize;

#[derive(Deserialize)]
struct GreetParams {
    name: String,
}

#[tokio::main]
async fn main() {
    let app = Router::new().route(
        "/greet",
        get(|Query(params): Query<GreetParams>| async move {
            format!("Hello, {}!", params.name)
        }),
    );

    axum::Server::bind(&([127, 0, 0, 1], 3000).into())
        .serve(app.into_make_service())
        .await
        .unwrap();
}

Test it with:

$ curl "http://127.0.0.1:3000/greet?name=Het"

🔒 Handling Authentication and Security

JWT (JSON Web Tokens): For user authentication.
OAuth: Integrate with third-party services like Google or GitHub.
HTTPS: Use TLS to encrypt communication.

Example: Middleware for Authentication

use actix_web::{dev::ServiceRequest, Error, HttpMessage};
use actix

_web_httpauth::middleware::HttpAuthentication;

async fn validator(req: ServiceRequest, _: actix_web::dev::Payload) -> Result<ServiceRequest, Error> {
    if let Some(auth_header) = req.headers().get("Authorization") {
        if auth_header == "Bearer secret-token" {
            return Ok(req);
        }
    }
    Err(actix_web::error::ErrorUnauthorized("Unauthorized"))
}

App::new().wrap(HttpAuthentication::with_fn(validator));

Middleware allows you to intercept requests or responses to add extra behavior like logging or authentication.

or

Middleware allows us to apply transformations, authentication, or logging.

🔑 Adding Middleware

use axum::{middleware, routing::get, Router};

async fn log_middleware<B>(req: axum::http::Request<B>) -> axum::http::Request<B> {
    println!("Request: {:?}", req);
    req
}

#[tokio::main]
async fn main() {
    let app = Router::new()
        .route("/", get(|| async { "Home Page" }))
        .layer(middleware::from_fn(log_middleware));

    axum::Server::bind(&([127, 0, 0, 1], 3000).into())
        .serve(app.into_make_service())
        .await
        .unwrap();
}

🔑 Adding Middleware

use axum::{middleware, routing::get, Router};
use tower_http::trace::TraceLayer;

#[tokio::main]
async fn main() {
    let app = Router::new()
        .route("/", get(|| async { "Hello, Middleware!" }))
        .layer(TraceLayer::new_for_http());

    axum::Server::bind(&([127, 0, 0, 1], 3000).into())
        .serve(app.into_make_service())
        .await
        .unwrap();
}

📲 Adding Authentication

You can handle token-based authentication using extractors:

use axum::{extract::Extension, middleware, routing::get, Router};

async fn check_auth<B>(
    req: axum::http::Request<B>,
) -> Result<axum::http::Request<B>, axum::http::Response<axum::body::Body>> {
    if let Some(auth) = req.headers().get("Authorization") {
        if auth == "Bearer mysecrettoken" {
            return Ok(req);
        }
    }
    Err(axum::http::Response::builder()
        .status(401)
        .body("Unauthorized".into())
        .unwrap())
}

#[tokio::main]
async fn main() {
    let app = Router::new()
        .route("/", get(|| async { "Secure Zone!" }))
        .layer(middleware::from_fn(check_auth));

    axum::Server::bind(&([127, 0, 0, 1], 3000).into())
        .serve(app.into_make_service())
        .await
        .unwrap();
}

🔐 Securing the Server

Securing your server involves implementing HTTPS and robust authentication mechanisms. Here's a detailed guide with examples:

1. Using HTTPS with TLS

HTTPS ensures that the communication between your server and clients is encrypted, preventing data interception and tampering. In Rust, you can use libraries like hyper-rustls or rustls to add TLS (Transport Layer Security) support.

Steps to Add HTTPS:

Install Dependencies Add the required crates to your Cargo.toml file:

[dependencies]
hyper = "0.14"
hyper-rustls = "0.23"
tokio = { version = "1", features = ["full"] }

Generate SSL Certificates Use tools like Let's Encrypt or OpenSSL to create certificates. For development purposes, generate self-signed certificates:
```
openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365 -nodes
```
This creates key.pem (private key) and cert.pem (certificate).

Set Up the TLS Configuration Here's an example of a basic HTTPS server using hyper and hyper-rustls:

use hyper::service::{make_service_fn, service_fn};
use hyper::{Body, Request, Response, Server};
use hyper_rustls::{HttpsConnectorBuilder, ServerConfig};
use std::sync::Arc;
use tokio::fs::read;

async fn handle_request(_req: Request<Body>) -> Result<Response<Body>, hyper::Error> {
    Ok(Response::new(Body::from("Hello, HTTPS World!")))
}

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Load SSL certificates
    let certs = read("cert.pem").await?;
    let key = read("key.pem").await?;

    let tls_config = ServerConfig::builder()
        .with_safe_defaults()
        .with_no_client_auth()
        .with_single_cert(certs, key)?;

    let tls_acceptor = Arc::new(tls_config);

    let addr = ([127, 0, 0, 1], 443).into();

    let make_svc = make_service_fn(|_conn| async { Ok::<_, hyper::Error>(service_fn(handle_request)) });

    let server = Server::builder(HttpsConnectorBuilder::new(tls_acceptor).build())
        .serve(make_svc);

    println!("HTTPS Server running on https://{}", addr);
    server.await?;

    Ok(())
}

This server listens on port 443 and serves encrypted content using HTTPS.

2. Adding Authentication

Authentication ensures only authorized users can access certain parts of your application.

Option 1: Basic Authentication

Basic Authentication sends a username and password with each request (over HTTPS). Example:

use hyper::{header, Body, Request, Response, StatusCode};

async fn handle_request(req: Request<Body>) -> Result<Response<Body>, hyper::Error> {
    if let Some(auth) = req.headers().get(header::AUTHORIZATION) {
        if auth == "Basic dXNlcjpwYXNzd29yZA==" { // user:password base64
            return Ok(Response::new(Body::from("Welcome, authenticated user!")));
        }
    }
    let mut response = Response::new(Body::from("Unauthorized"));
    *response.status_mut() = StatusCode::UNAUTHORIZED;
    Ok(response)
}

Option 2: Token-Based Authentication (JWT)

JWT (JSON Web Tokens) are a more secure and scalable way to handle authentication.

Add Dependencies:

[dependencies]
jsonwebtoken = "8"
serde = { version = "1.0", features = ["derive"] }

Generate and Verify Tokens: Example:

use jsonwebtoken::{encode, decode, Header, Algorithm, Validation, EncodingKey, DecodingKey};
use serde::{Serialize, Deserialize};

#[derive(Debug, Serialize, Deserialize)]
struct Claims {
    sub: String,
    exp: usize,
}

fn generate_jwt() -> String {
    let my_claims = Claims { sub: "user1".to_owned(), exp: 10000000000 };
    encode(&Header::default(), &my_claims, &EncodingKey::from_secret("secret".as_ref())).unwrap()
}

fn verify_jwt(token: &str) -> bool {
    decode::<Claims>(token, &DecodingKey::from_secret("secret".as_ref()), &Validation::new(Algorithm::HS256)).is_ok()
}

fn main() {
    let token = generate_jwt();
    println!("Generated JWT: {}", token);

    let is_valid = verify_jwt(&token);
    println!("Token is valid: {}", is_valid);
}

Use JWT in Headers for Secure Communication.

Practices for Security

Always use HTTPS in production.
Store secrets securely (e.g., use environment variables).
Use well-tested libraries for authentication.
Regularly update dependencies to patch vulnerabilities.

📦 Working with JSON and APIs

📤 Building REST APIs

Develop endpoints for CRUD operations:

use axum::{routing::get, Router, Json};
use serde::{Deserialize, Serialize};

#[derive(Serialize)]
struct User {
    id: u32,
    name: String,
}

async fn get_user() -> Json<User> {
    Json(User {
        id: 1,
        name: "Het Patel".to_string(),
    })
}

#[tokio::main]
async fn main() {
    let app = Router::new().route("/user", get(get_user));

    axum::Server::bind(&([127, 0, 0, 1], 3000).into())
        .serve(app.into_make_service())
        .await
        .unwrap();
}

📡 REST APIs

REST APIs are integral to web development. Use serde for JSON serialization/deserialization.

Creating a REST API

use axum::{extract::Json, routing::post, Router};
use serde::Deserialize;

#[derive(Deserialize)]
struct CreateUser {
    name: String,
}

async fn create_user(Json(payload): Json<CreateUser>) -> String {
    format!("User {} created", payload.name)
}

#[tokio::main]
async fn main() {
    let app = Router::new().route("/user", post(create_user));

    axum::Server::bind(&([127, 0, 0, 1], 3000).into())
        .serve(app.into_make_service())
        .await
        .unwrap();
}

📥 Handling JSON Payloads

#[derive(Deserialize)]


struct CreateUser {
    name: String,
}

async fn create_user(Json(payload): Json<CreateUser>) -> String {
    format!("User {} created", payload.name)
}

🌐 Building a Simple Full-Stack Application

Let’s take it up a notch! 🚀 Here's how to integrate Rust for your backend and use React or Vue.js for the frontend. We'll create a TODO App as an example.

Backend: REST API with Rust

We'll use axum for routing and serde for JSON serialization.

Setup a POST endpoint to add a task:

use axum::{extract::Json, routing::post, Router};
use serde::{Deserialize, Serialize};

#[derive(Deserialize, Serialize)]
struct Task {
    id: usize,
    title: String,
    completed: bool,
}

async fn add_task(Json(task): Json<Task>) -> Json<Task> {
    // Ideally, store tasks in a database; here, we'll just return it.
    Json(task)
}

#[tokio::main]
async fn main() {
    let app = Router::new().route("/add_task", post(add_task));

    axum::Server::bind(&([127, 0, 0, 1], 3000).into())
        .serve(app.into_make_service())
        .await
        .unwrap();
}

Frontend: Call the API Using fetch or axios in React:

async function addTask(task) {
    const response = await fetch("http://127.0.0.1:3000/add_task", {
        method: "POST",
        headers: { "Content-Type": "application/json" },
        body: JSON.stringify(task),
    });
    const data = await response.json();
    console.log(data);
}

Test the Integration: Use Postman or the browser console to ensure the backend and frontend are talking smoothly.

use warp::Filter;

#[tokio::main]
async fn main() {
    let route = warp::path!("hello" / String)
        .map(|name| format!("Hello, {}!", name));

    warp::serve(route)
        .run(([127, 0, 0, 1], 3030))
        .await;
}

4️⃣ Axum

Features:
- Designed for ergonomics and performance.
- Leverages tokio and tower for async and middleware.
Use Case:
- A balance between simplicity and scalability.

use axum::{Router, routing::get};

async fn handler() -> &'static str {
    "Welcome to Axum!"
}

#[tokio::main]
async fn main() {
    let app = Router::new().route("/", get(handler));
    axum::Server::bind(&"127.0.0.1:4000".parse().unwrap())
        .serve(app.into_make_service())
        .await
        .unwrap();
}

🛠️ Building a Simple Web Server

Let’s build a basic REST API with Actix Web.

Steps:

Setup Project: Add dependencies to Cargo.toml:

[dependencies]
actix-web = "4.0"
serde = { version = "1.0", features = ["derive"] }

Define API Endpoints:

use actix_web::{web, App, HttpServer, Responder};
use serde::Serialize;

#[derive(Serialize)]
struct Message {
    text: String,
}

async fn hello() -> impl Responder {
    web::Json(Message { text: "Hello, Actix!".to_string() })
}

#[tokio::main]
async fn main() -> std::io::Result<()> {
    HttpServer::new(|| {
        App::new().route("/hello", web::get().to(hello))
    })
    .bind("127.0.0.1:8080")?
    .run()
    .await
}

Run and Test: Start the server and access the endpoint at http://127.0.0.1:8080/hello.

🌟 Exploring APIs and Routes

Dynamic Routing:

async fn greet(name: web::Path<String>) -> impl Responder {
    format!("Hello, {}!", name)
}

App::new().route("/greet/{name}", web::get().to(greet));

Middleware: Add logging, authentication, or custom behavior.

use actix_web::middleware::Logger;

App::new()
    .wrap(Logger::default())
    .route("/", web::get().to(index));

🗄️ Database Integration

Rust provides great database support through libraries like:

Diesel: Strongly-typed ORM.
SQLx: Async and lightweight.

Example with SQLx:

use sqlx::sqlite::SqlitePool;

#[tokio::main]
async fn main() -> Result<(), sqlx::Error> {
    let pool = SqlitePool::connect("sqlite::memory:").await?;

    sqlx::query("CREATE TABLE users (id INTEGER PRIMARY KEY, name TEXT)")
        .execute(&pool)
        .await?;

    sqlx::query("INSERT INTO users (name) VALUES ('Alice')")
        .execute(&pool)
        .await?;

    let row: (i64, String) = sqlx::query_as("SELECT id, name FROM users WHERE name = 'Alice'")
        .fetch_one(&pool)
        .await?;

    println!("User: {} with ID {}", row.1, row.0);
    Ok(())
}

🚀 Deploying Rust Web Applications

Containerization: Use Docker to package your application.
Hosting:
- Cloud services like AWS, Azure, or DigitalOcean.
- Serverless platforms like Fly.io or Vercel.

Example Dockerfile:
