Web Development in Rust: From Basics to Deployment

This book is your guide to the world of web development in Rust. You will start with the basics of the language, master key concepts, and gradually move on to creating full-fledged web applications. Rust is not just a fast and safe language; it offers unique opportunities for building reliable and high-performance web services.

The book is divided into three logical parts:

• Rust Basics for the Web: A quick dive into syntax, ownership, borrowing, lifetimes, structs, and enums. You will learn to write safe and efficient code from scratch.
• Building the Backend: A detailed study of the Actix-web and Rocket frameworks. You will learn how to handle HTTP requests, work with routing, middleware, serialization/deserialization (Serde), authentication, authorization, and interaction with databases (SQLx, Diesel).
• Frontend and Deployment: Introduction to Yew, a framework for building reactive web interfaces in Rust (WASM). You will build a complete SPA application. The book concludes with a section on deployment: setting up CI/CD, containerization with Docker, and deploying to a server (VPS, Heroku, DigitalOcean).

Who this book is for:

• Developers familiar with other languages (Python, Java, C++) who want to learn Rust for the web.
• Beginner Rust programmers who want to apply their knowledge in practice.
• Backend developers looking for a high-performance alternative to Node.js or Go.

What you will learn:

• How to set up the environment and organize a Rust project.
• How to create REST APIs with Actix-web and Rocket.
• How to work with asynchrony (Tokio, async/await).
• How to connect and use PostgreSQL, MySQL, and SQLite.
• How to write unit tests and integration tests.
• How to create a client-side application with Yew and WebAssembly.
• How to optimize application performance and security.
• How to deploy an application to production.

All code examples are available in the repository and ready to run. The book is written in a lively, clear language with an emphasis on practice. After reading it, you will be able to independently develop and deploy web applications in Rust of any complexity.
