Building a Rust Web Server with Axum

Rust has become increasingly popular for building web services due to its performance, safety, and excellent ecosystem. In this post, I'll walk through building a web server using Axum.

Why Axum?

Axum is a web framework built on top of Tokio and Hyper. It offers:

  • Type Safety: Leverage Rust's type system for compile-time guarantees
  • Performance: Built on Tokio's async runtime
  • Ergonomics: Clean API with minimal boilerplate
  • Extractors: Powerful request extraction system

Getting Started

First, add Axum to your Cargo.toml:

[dependencies]
axum = "0.8"
tokio = { version = "1", features = ["full"] }

Creating Your First Route

Here's a simple example:

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

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

    let listener = tokio::net::TcpListener::bind("0.0.0.0:3000")
        .await
        .unwrap();
    
    axum::serve(listener, app).await.unwrap();
}

Next Steps

In future posts, I'll cover:

  • Handling JSON requests and responses
  • Database integration
  • Authentication and middleware
  • Template rendering with Askama

Stay tuned!
