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.

Displaying HTML in the browser from a server

So far, we have been processing data and returning it in JSON format. This is great, and we will be continuing to use this JSON format throughout the rest of this book. However, it is not very useful for a standard user. We need the data to be displayed when the user visits the URL. This view utilizes buttons and forms, enabling the user to interact with the API endpoints. Before this, we had to use Postman to interact with those APIs.

There are a couple of crates that enable developers to render HTML for users in Rust. In order to do this, we will need to structure our own app views module, which takes the following structure:

└── views
├── app
│   ├── items.rs
│   └── mod.rs

In our items.rs file, we will be defining the main view that displays the to-do items. However, before we do that, we should explore...
