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.

Setting up our server

We need to set up a server in order to listen to requests, process them, and route them to specific views based on their URLs. This server will be the entry point to our application. In order to build our server, we must follow these steps:

  1. First, we will build our own cargo project and define our dependency on the Rocket frame with the following dependency, which can be found in the Cargo.toml file:
    [dependencies]
    tokio = { version = "0.2", features = ["full"] }
    warp = "0.2"
  2. Now, we can build our basic server with just one view in out src/main.rs file. First of all, we will import what we need with the following code:
    use warp::Filter;

    This is all we need to import.

    With this simple import statement, Warp provides us with a lot of tools. To demonstrate this, we are going to define some routes, pass in parameters, return some JSON, and launch a server. Essentially, Filter can extract some data from requests. This data can...
