Axum provides type-safe routing and extractors for REST API handlers. Define routes with path parameters, use typed extractors to parse requests into Rust structs automatically, and return JSON responses. This ensures compile-time correctness and prevents serialization errors.

Axum integrates with Tower middleware for layered request processing. Use middleware to add cross-cutting concerns like logging and authentication. Share application state via type-safe extractors, avoiding runtime errors from shared mutable state patterns.

Implement structured error handling by defining custom error types that convert to HTTP responses. Combine with logging middleware to capture request traces and errors. This approach enables debugging and monitoring in production deployments.

Yes. Axum supports WebSocket, SSE, and REST handlers within the same application. Route different protocol handlers to specific paths and reuse middleware and state management across all handler types for cohesive production deployments.

Production Axum services require graceful shutdown handling, proper error logging, health checks, and state initialization. Tower middleware patterns and structured error responses simplify containerization and observability for cloud deployments.
