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.

Section 3:Data Persistence

Data persistence is essential for modern day web applications as the demand on web applications is increasing. Luckily Rust has tools that can enable data persistence on PostgreSQL and other databases. With these tools combined with JSON Web Tokens, we can manage the user sessions on our Rust application.

However, this is not the end of data persistence. Due to the increasing demand on web applications, we also have to optimize the persistence, reading, and writing of our data. This is where RESTful service concepts come in handy. Implementing these concepts will have us caching data in our frontend with JavaScript to prevent excessive strain on our Rust application and improve the user's experience. Logging processes in our server are also going to be a good way to determine where to optimize them.

This section focuses on persisting data through a PostgreSQL database and managing it through Docker and the Diesel crate. It also covers migrations...
