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.

Authenticating our requests

Throughout this book, we have been intercepting the HTTP requests before they can hit the view in order to inspect the header and extract the token. If the token couldn't be verified when we interacted with to-do item views, we rejected the request and gave an unauthorized response to the user.

In Actix, we built middleware that inspected the requests before they hit the server view. In Rocket, we implemented request guards to reject the request if it did not have the authentication needed to make the request.

With Warp, we are going to follow a different approach: we are going to add another filter to our view. In this section, we are going to apply this filter to our GET view in order to get the to-do items that belong to the user. We can achieve this by doing the following:

  1. Adding a header extraction filter to our view.
  2. Configuring our own JWT to check whether the token that's been supplied is correct.
  3. Using the token to...
