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.

Building our PostgreSQL database

In this section, we will be able to monitor the state of Docker containers, and configure and run a PostgreSQL database Docker container. So far, we have been using a JSON file to store our to-do items. This has served us well so far. In fact, there is no reason why we cannot use a JSON file throughout the rest of the book. However, there are some downsides to this outside of the book.

If the reads and writes to our JSON file increase, then we can have some concurrency issues and data corruption. There is also no checking on the type of data. Therefore, another developer can write a function that writes different data to the JSON file, and nothing will stand in the way.

There is also an issue with migrations. If we want to add a timestamp to the to-do items, this will only affect new to-do items that we insert into the JSON file. Therefore, some of our to-do items will have a timestamp, and others won't, which would introduce bugs into our...
