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.

Code on demand

Code on demand is where the backend server directly executes code on the frontend. This constraint is optional and not widely used. However, it can be useful as it gives the backend server the right to decide as and when code is executed on the frontend. We have already been doing this; in our logout view, we directly execute JavaScript on the frontend by simply returning it in a string. This is done in the src/views/auth/logout.rs file. We must remember that we have now added to-do items to our local storage. If we do not remove these items from our local storage when logging out, somebody else would be able to access our to-do items if they manage to log in to their own account on the same computer within 2 minutes. While this is highly unlikely, we might as well be safe. Remember that our logout view in the src/views/auth/logout.rs file takes the following form:

pub async fn logout() -> HttpResponse {
    HttpResponse::Ok()
