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.

In this chapter, we have finally enabled our application to be used by a casual user as opposed to having to rely on a third-party application such as Postman. We defined our own app views module that housed read file and insert functions. This resulted in us building a process that loaded an HTML file, inserted data from JavaScript and CSS files into the view data, and then served that data.

This gave us a dynamic view that automatically updated when we edited, deleted, or created a to-do item. We also explored some basics around CSS and JavaScript to make API calls from the frontend and dynamically edit the HTML of certain sections of our view. We also managed the styling of the whole view based on the size of the window. Note that we did not rely on external crates. This is because we want to be able to understand how we can process our HTML data.

Then, we rebuilt the frontend in React. While this took longer and there were more moving parts, the code was more scalable...
