Book Description

Rust is no longer just for systems programming. This book will show you why this safe and performant language is a crucial up-and-coming option for developing web applications, and get you on your way to building fully functional Rust web apps. You don’t need any experience with Rust to get started, and this new edition also comes with a shallower learning curve.

You’ll get hands-on with emerging Rust web frameworks including Actix, Axum, Rocket, and Hyper. You’ll look at injecting Rust into the frontend with WebAssembly and HTTPS configuration with NGINX. Later, you’ll move on to more advanced async topics, exploring TCP and framing, and implementing async systems.

As you work through the book, you’ll build a to-do application with authentication using a microservice architecture that compiles into one Rust binary, including the embedding of a frontend javascript application in the same binary. The application will have end-to-end atomic testing and a deployment pipeline.

By the end of this book, you’ll fully understand the significance of Rust for web development. You’ll also have the confidence to build robust, functional, and scalable Rust web applications from scratch.
What you will learn

Build scalable Rust web applications as monoliths or microservices
Develop a deeper understanding of async Rust
Get to grips with Rust language features such as traits and the borrow checker
Manage authentication and databases in Rust web apps
Build app infrastructure on AWS using Terraform
Learn how to package and deploy Rust servers

Who this book is for

This book is for web developers who are looking to learn or adopt Rust to build safe and performant web applications. This includes developers familiar with languages such as Python, Ruby, and javascript.

You don’t need any prior experience in Rust to start this book. However, you’ll need a solid understanding of web development principles, along with basic knowledge of HTML, CSS, and javascript to get the most out of it.
