To build a web API with Axum, you use its type-safe routing and extractor system to handle requests, compose Tower middleware, and manage shared state. This approach enables fast, scalable Rust web services.

Axum middleware composition works by wrapping routes or routers with Tower-based layers. This mechanism allows you to sequentially process requests for logging, authentication, and error handling before they reach your core Axum handlers.

Yes, you can use Axum for production-grade web services with WebSockets. Axum provides guidance on WebSocket support, robust error handling, database migrations, and scalable deployment patterns necessary for production environments.

The best way to manage shared state in an Axum application is by using Axum's built-in state management features to pass shared data through extractors. This ensures type-safe access to common resources across your request handlers.

Axum uses extractors for request payload handling to achieve type-safe routing and automatic deserialization. Extractors transform incoming request data into typed Rust objects, reducing boilerplate and ensuring your handlers receive validated data.

Choose Axum over other Rust web frameworks when you need tight integration with Tokio and Tower for middleware composition. Axum excels in scenarios requiring type-safe routing, scalable deployment, and a modular ecosystem for production APIs.
