Axum

Axum is a modern web framework for Rust. Here’s how to build your first API. Setup [dependencies] axum = "0.7" tokio = { version = "1", features = ["full"] } serde = { version = "1.0", features = ["derive"] } Basic Server use axum::{Router, routing::get, Json}; #[tokio::main] async fn main() { let app = Router::new() .route("/", get(handler)); axum::Server::bind(&"0.0.0.0:3000".parse().unwrap()) .serve(app.into_make_service()) .await .unwrap(); } async fn handler() -> Json<serde_json::Value> { Json(serde_json::json!({"message": "Hello, World!"})) } Routes let app = Router::new() .route("/users", get(get_users)) .route("/users/:id", get(get_user)); JSON Handling use serde::{Deserialize, Serialize}; #[derive(Serialize, Deserialize)] struct User { id: u32, name: String, } async fn create_user(Json(user): Json<User>) -> Json<User> { Json(user) } Best Practices Use type-safe routing Handle errors properly Use middleware Test endpoints Document APIs Conclusion Build fast and safe APIs with Rust and Axum! 🦀
