Rust Web Development with Rocket

By: Karuna Murti

Overview of this book

Looking for a fast, powerful, and intuitive framework to build web applications? This Rust book will help you kickstart your web development journey and take your Rust programming skills to the next level as you uncover the power of Rocket - a fast, flexible, and fun framework powered by Rust. Rust Web Development with Rocket wastes no time in getting you up to speed with what Rust is and how to use it. You’ll discover what makes it so productive and reliable, eventually mastering all of the concepts you need to play with the Rocket framework while developing a wide set of web development skills. Throughout this book, you'll be able to walk through a hands-on project, covering everything that goes into making advanced web applications, and get to grips with the ins and outs of Rocket development, including error handling, Rust vectors, and wrappers. You'll also learn how to use synchronous and asynchronous programming to improve application performance and make processing user content easy. By the end of the book, you'll have answers to all your questions about creating a web application using the Rust language and the Rocket web framework.

Writing a WebAssembly application using Yew

In the application, we are going to use Yew (https://yew.rs). On the website, it says that Yew is a modern Rust framework for creating multithreaded frontend web apps.

Cargo can compile the WebAssembly binary, but the WebAssembly binary itself is not usable without other steps. We have to load the WebAssembly binary in the web browser's virtual machine engine. There are proposals such as using a <script type="module"></script> tag, but unfortunately, those proposals are not standard yet. We have to tell JavaScript to load the module using the WebAssembly Web API. To make the development easier, we can use wasm-pack from the Rust WebAssembly working group at https://rustwasm.github.io/. Yew uses an application named trunk (https://trunkrs.dev) that wraps wasm-pack and provides other conveniences. Install trunk by using this command:

cargo install --locked trunk

Now that the preparation for compiling WebAssembly...
