Building front-end applications with Rust and WebAssembly

Yew is a modern Rust framework for creating multi-threaded front-end web applications, which uses WebAssembly Technology Implementation Performance optimization. This framework supports interoperability with JavaScript, allowing it to not only execute JS code, but also communicate bidirectionally between Rust and JavaScript. The Yew framework has a component-based design pattern similar to React and Elm, and is particularly outstanding in building rich and high-performance web applications because it can leverage Rust’s powerful ecosystem.

In this article, we will explore in depth how to use the Yew framework to build front-end applications, and provide detailed steps and rich examples to help you deeply understand how to develop WebAssembly front-end applications.

Create a new project

First, make sure you have installed Rust. Then, create a new project with the following command:

cargo new --lib yew-app

Switch to the created project directory and edit the Cargo.tomlfile to add the Yew dependency.

[dependencies]
yew = "0.18"

Configure multithreading

The Yew framework supports a multi-threaded model, which can be implemented through Web Workers. This requires the following adjustments to the index.htmland Cargo configurations:

<!--  index.html  -->
<script type="module">
  import…
