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.

Building continuous integration with GitHub Actions

When it comes to ensuring that code quality is maintained, it can be handy to have a continuous integration pipeline that will run every time a pull request is done. We can do this with GitHub Actions. It must be noted that with GitHub Actions, you get several free minutes every month; then, you must pay for the minutes you go over. So, be careful and keep an eye on how much time you’re spending using GitHub Actions.

GitHub Actions gives us flexibility when it comes to implementing tasks. We can run workflows when a pull request is merged or made and when an issue is created and much more. We can also be selective about the type of branches we use. In this example, we will merely focus on a pull request on any branch to run unit tests and then full integration tests.

To build a workflow called tests, we need to create a file called .github/workflows/run-tests.yml. In this file, we will define the general outline of the...
