Rust Web Programming - Second Edition

Overview of this book

Are safety and high performance a big concern for you while developing web applications? With this practical Rust book, you’ll discover how you can implement Rust on the web to achieve the desired performance and security as you learn techniques and tooling to build fully operational web apps. In this second edition, you’ll get hands-on with implementing emerging Rust web frameworks, including Actix, Rocket, and Hyper. It also features HTTPS configuration on AWS when deploying a web application and introduces you to Terraform for automating the building of web infrastructure on AWS. What’s more, this edition also covers advanced async topics. Built on the Tokio async runtime, this explores TCP and framing, implementing async systems with the actor framework, and queuing tasks on Redis to be consumed by a number of worker nodes. Finally, you’ll go over best practices for packaging Rust servers in distroless Rust Docker images with database drivers, so your servers are a total size of 50Mb each. By the end of this book, you’ll have confidence in your skills to build robust, functional, and scalable web applications from scratch.

Data Persistence with PostgreSQL

By this point in the book, the frontend for our application has 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 will get rid of our JSON file and introduce a PostgreSQL database to store our data. We will do this by setting up a database development environment using Docker. We will also investigate how to monitor the Docker database container. We will then create migrations to build the schema for our database and then build data models in Rust to interact with the database. We will 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
  • Configuring our application
  • Managing a database connection pool...
