## Basic Setup
```toml
# Cargo.toml
[dependencies]
axum = "0.7"
tokio = { version = "1", features = ["full"] }
serde = { version = "1", features = ["derive"] }
tower-http = { version = "0.5", features = ["cors", "trace"] }
```
```rust
use axum::{routing::get, Router};
async fn hello() -> &'static str {
"Hello, World!"
}
#[tokio::main]
async fn main() {
let app = Router::new().route("/", get(hello));
let listener = tokio::net::TcpListener::bind("0.0.0.0:8080").await.unwrap();
axum::serve(listener, app).await.unwrap();
}
```
## Routing
```rust
let app = Router::new()
.route("/", get(index))
.route("/users", get(list_users).post(create_user))
.route("/users/:id", get(get_user).put(update_user).delete(delete_user));
// Nested Routes
let api_routes = Router::new()
.route("/users", get(list_users));
let app = Router::new().nest("/api/v1", api_routes);
```
## Extractors
```rust
use axum::extract::{Path, Query, Json, State};
// Path parameters
async fn get_user(Path(id): Path<u32>) -> String {
format!("User {}", id)
}
// Query parameters
#[derive(Deserialize)]
struct Pagination { page: Option<u32>, per_page: Option<u32> }
async fn list_users(Query(pagi
