Rust Web Programming

By: Maxwell Flitton

Overview of this book

Are safety and high performance a big concern for you while developing web applications? While most programming languages have a safety or speed trade-off, Rust provides memory safety without using a garbage collector. This means that with its low memory footprint, you can build high-performance and secure web apps with relative ease. This book will take you through each stage of the web development process, showing you how to combine Rust and modern web development principles to build supercharged web apps. You'll start with an introduction to Rust and understand how to avoid common pitfalls when migrating from traditional dynamic programming languages. The book will show you how to structure Rust code for a project that spans multiple pages and modules. Next, you'll explore the Actix Web framework and get a basic web server up and running. As you advance, you'll learn how to process JSON requests and display data from the web app via HTML, CSS, and JavaScript. You'll also be able to persist data and create RESTful services in Rust. Later, you'll build an automated deployment process for the app on an AWS EC2 instance and Docker Hub. Finally, you'll play around with some popular web frameworks in Rust and compare them. By the end of this Rust book, you'll be able to confidently create scalable and fast web applications with Rust.

What are RESTful services?

REST stands for representational state transfer. It is an architectural style for our application programming interface (API) in order to read (GET), update (PUT), create (POST), and delete (DELETE) our users and to-do items. The goal of a RESTful approach is to increase speed/performance, reliability, and the ability to grow by reusing components that can be managed and updated without affecting the system as a whole.

You may have noticed that before Rust, slow, high-level languages seemed to be a wise choice for web development. This is because they are quicker and safer to write. This is due to the main bottleneck for speed in web development being network connection speed. The RESTful design aims to improve the speed by economizing the system as a whole, such as reducing API calls as opposed to just focusing on algorithm speed. With that in mind, in this section, we will be covering the following RESTful concepts:
