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.

Setting up a local development database

When it comes to migrations, there is the advantage of decoupling the programming language that we are using from the migrations. In the past, I have had to switch servers from one language to another and simply wished that the migration’s implementation was not coupled with the language. This is also a deployment issue. For instance, in Kubernetes, deploying a new server or an update might require a migration to be run. Ideally, you want to run the migration automatically through what we call init Pods. This is a container that is spun up and executed before the main server is deployed. This init Pod can perform a database migration command. However, if the init Pod requires something such as Rust to be present to execute the migration, this can greatly increase the size of the init pod. Therefore, I built an open source Bash tool that is only dependent on the psql and wget libraries. It can create new migrations and roll the database...
