Practical Rust Web Projects: Building Cloud and Web-Based Applications

Build Real-World Web Applications with Rust 💻

Rust has earned a reputation for combining performance with memory safety, and its web ecosystem is growing fast. Practical Rust Web Projects takes you beyond the basics and into the practical work of building web applications, APIs, and cloud services with Rust. Whether you are a Rust developer curious about web programming or a web developer exploring Rust, this book provides a project-driven path to getting things done.

What You’ll Build

The book guides you through a series of interconnected projects that cover:

• Dynamic websites using Actix Web and template rendering
• REST APIs with JSON responses and custom error handling
• Real-time communication with WebSocket for chat and notifications
• Serverless deployment on AWS Lambda with the Serverless Framework
• High-performance frontends powered by WebAssembly and Yew

From Web Apps to Serverless and WebAssembly ⚙️

Early chapters establish a foundation with Actix Web, showing how to handle routing, templates, and API design. You then move into WebSocket territory, learning to push updates from server to client and manage connections cleanly. The serverless chapter walks through creating an AWS account, building a REST API with Lambda, and using S3 presigned URLs for uploads. The final chapters explore WebAssembly—first resizing images with Wasm, then reimplementing the frontend entirely in Rust with Yew. Each project builds on the last, reinforcing concepts through repetition and variation.

Who This Book Is For

This book assumes you already know Rust fundamentals—ownership, traits, and Cargo—and are ready to apply them to web development. It is not an introduction to Rust itself. If you are comfortable with the language and want to explore web frameworks, cloud deployment, or WebAssembly, the projects here will meet you at your level. Developers coming from other web stacks will find the Rust-specific patterns clearly explained, while Rust enthusiasts will appreciate the practical, no-nonsense approach.

About the Author

Shing Lyu is a software engineer who has worked with Rust professionally at Mozilla on the Firefox (Gecko) and Servo browser engine projects. He currently works at DAZN as a backend developer focusing on AWS and serverless technology. A founder of the Taiwan Rust community, he brings both deep technical knowledge and a passion for sharing Rust with others.

Why Rust for Web Development? 🚀

Rust offers performance comparable to C++ with memory safety guarantees, making it attractive for web services that need to be both fast and reliable. As more companies adopt Rust in production, the ability to build web applications and cloud functions in Rust becomes a valuable skill. This book helps you acquire that skill through concrete, working code that you can adapt to your own projects.
