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.

Injecting CSS into HTML

Injecting CSS follows the same approach as injecting JavaScript. We will have a CSS tag in the HTML file that will be replaced with the CSS from the file. To achieve this, we must carry out the following steps:

  1. Add CSS tags to our HTML file.
  2. Create a base CSS file for the whole app.
  3. Create a CSS file for our main view.
  4. Update our Rust crate to serve the CSS and JavaScript.

Let us have a closer look at the preceding steps by initially adding CSS tags to our HTML files with the following sections.

Adding CSS tags to our HTML file

First of all, let's make some changes to our templates/main.html file:

<style>
    {{BASE_CSS}}
    {{CSS}}
</style>
<body>
    <div class="mainContainer">
        <h1>Done Items</h1>
        <div id="doneItems...
