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.

Chapter 8: Building RESTful Services

Our to-do application written in Rust technically works. However, there are some improvements that we need to make. In this chapter, we will apply these improvements as we explore the concepts of RESTful API design.

In this chapter, we finally reject unauthorized users before the request hits the view by assessing the layers of our system and refactoring it to handle before and after request data. We then use this authentication to enable individual users to have their own list of to-do items. Finally, we log our requests so that we can troubleshoot our application and get a deeper look into how our application runs, caching data in the frontend to reduce API calls. We also explore nice-to-have concepts such as executing code on command and creating a uniform interface to split the frontend URLs from the backend URLs.

In this chapter, we will cover the following topics:

  • What are RESTful services?
  • Breaking down the application...
