API Development in Rust: From Basics to Production

The book "API Development in Rust: From Basics to Production" is a comprehensive guide to creating modern, fast, and reliable web interfaces in the Rust language. The author, Alexey Petrov, drawing on years of experience in systems programming and web technologies, guides the reader step by step from the first lines of code to deploying a finished API in the cloud.

What is this book about?

The book starts with the basics: you will get acquainted with Rust syntax, the ownership and borrowing system, and the key concepts necessary for web development. Next, you will dive into the world of HTTP and RESTful APIs, learn how to handle requests, manage routing, and work with JSON, XML, and forms.

Special attention is given to the two most popular frameworks: Actix-web and Rocket. You will learn how to choose the right tool for your project, how to organize middleware, handle errors, and implement authentication (JWT, OAuth2).

Who is this book for?

• Rust developers who want to transition from console utilities to web services.
• Backend developers looking to master Rust for building high-load APIs.
• Students and professionals interested in modern approaches to creating microservices.
• Anyone who wants to understand how to leverage Rust's advantages (memory safety, asynchronicity) in a web context.

What will you learn and discover?

• Setting up a project from scratch using Cargo and popular crates.
• Creating RESTful APIs with support for CRUD operations.
• Working with databases (PostgreSQL, SQLite) via Diesel and SQLx.
• Implementing asynchronous handlers using Tokio and async/await.
• Writing tests for APIs, including integration tests and load testing.
• Configuring logging, monitoring, and error handling.
• Deploying applications in Docker and on servers (AWS, DigitalOcean).

Why should you read this book?

Rust is a language that combines the performance of C++ with memory safety, making it ideal for building reliable APIs. Unlike many other books, this guide is not limited to theory: each chapter contains practical examples that can be immediately applied in your work. You will learn not only to write code but also to design architecture, optimize performance, and avoid common mistakes.

The book is written in a lively, accessible language; complex topics are explained through clear diagrams and step-by-step instructions. At the end of each chapter, there are self-assessment tasks to help reinforce the material.

Reader reviews:

"Finally, a book that doesn't just paraphrase the documentation but teaches you to think like an API developer in Rust." — Ivan, backend engineer.

"An excellent introduction to Actix-web. After reading it, I was able to rewrite my microservice from Go to Rust in a week." — Elena, DevOps engineer.

Contents: from the basics of HTTP and tool installation to advanced topics: WebSocket, gRPC, integration with Redis and Kafka. Perfect for self-study
