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.

Chapter 6: Data Persistence with PostgreSQL

The frontend has now been defined, and our app is working at face value. However, we know that our app is reading and writing from a JSON file.

In this chapter, we get rid of our JSON file and introduce a PostgreSQL database to store our data. We do this by setting up a database development environment using Docker. We also look into how to monitor the Docker database container. We then create migrations in order to build the schema for our database, and then build data models in Rust to interact with the database. We then refactor our app so that the create, edit, and delete endpoints interact with the database instead of the JSON file.

In this chapter, we will cover the following topics:

  • Building our PostgreSQL database
  • Connecting to PostgreSQL with Diesel
  • Connecting our application to PostgreSQL
  • Creating our data models and migrations
  • Getting data from the database
  • Inserting data into the database
  • ...
