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.

Writing tests in Postman

In this section, we will be using Postman to test our API endpoints. This will test our JSON processing and database access. In order to do this, we will follow these steps:

  1. We are going to have to create a test user for our Postman tests. We can do this with the JSON body shown as follows:
    {
        "name": "test",
        "email": "[email protected]",
        "password": "test"
    }
  2. We need to add a POST request to the URL http://127.0.0.1:8000/api/v1/user/create. Once we have done this, we can use our login endpoint for our Postman tests. Now that we have created our test user, we have to get the token from the response header of the POST request to the URL http://127.0.0.1:8000/api/v1/auth/login with the JSON request body:
    {
        "username": "test",
        "password": "test...
