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.

Managing views using the Actix Web framework

In the Launching a basic Actix Web server section, we defined our views in the main.rs file. However, this is not scalable. If we continue to define all our routes in main, we will end up with a lot of imports and route definitions in one file. This makes it hard to navigate and manage. If we want to change a URL prefix for a block of views, the editing in this context is error-prone. The same goes for disabling a block of views.

In order to manage our views, we need to create our own modules for each set of views. To manage our views, we create a new Cargo project called managing_views. We then define the following project structure:

├── main.rs
└── views
    ├── auth
    │   ├── login.rs
    │   ├── logout.rs
