Building Web APIs with Axum and Rust: Create high-performance REST APIs with async handlers, middleware, database integration, and production deployme

By: Rao, Anik

Build fast reliable Rust APIs that are production ready from day one.

Shipping an HTTP service is more than routes and JSON. Teams struggle with timeouts, error surfaces, authentication, database performance, and dependable deploys that do not wake the on call. This book shows a practical path using Axum on top of Tokio, hyper, and Tower, so you can move from local prototype to stable production with confidence.

You will learn proven patterns for routing, extractors, middleware, observability, testing, and deployment, all shaped for Rust's async model and real workloads.
