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.

Injecting JavaScript into HTML

Once we have finished this section, we will have a not-so-pretty but fully functional main view where we can add, edit, and delete to-do items using JavaScript to make calls to our Rust server. However, as you may recall, we did not add a delete API endpoint. To inject JavaScript into our HTML, we will have to carry out the following steps:

  1. Create a delete item API endpoint.
  2. Add a JavaScript loading function and replace the JavaScript tag in the HTML data with the loaded JavaScript data in the main item Rust view.
  3. Add a JavaScript tag in the HTML file and IDs to the HTML components so that we can reference the components in our JavaScript.
  4. Build a rendering function for our to-do items in JavaScript and bind it to our HTML via IDs.
  5. Build an API call function in JavaScript to talk to the backend.
  6. Build the get, delete, edit, and create functions in JavaScript for our buttons to use.

Let’s have a detailed look...
