WebAssembly

Access JavaScript functions from Rust

In this tutorial, we will show you how to use the nodejs-helper crate to call Node.js functions from Rust code. Rust functions can now access the file system, network, database, and other system resources from within the WebAssembly container. It is important to note that a better way for Rust programs to access system resources is through the WebAssembly WASI extension, as well as numerous host extensions provided by the SSVM.…

WebAssembly in the browser

WebAssembly was originally invented as a technology solution to speed up code execution inside web browsers. It does not provide a full replacement for JavaScript, but rather works side-by-side with JavaScript. The idea is that JavaScript functions could pass computationally intensive tasks to WebAssembly functions. In this tutorial, we will demonstrate how a simple WebAssembly in-browser application works. The source code of the tutorial is here. A WebAssembly application typically has two parts.…

Rust and WebAssembly

In this tutorial, we will create a very simple but complete WebAssembly application. A WebAssembly application typically has two parts. The bytecode program that runs inside the WebAssembly virtual machine to perform computing tasks The host application that provides UI, networking, database, and calls the WebAssembly program to perform key computing tasks or business logic In this tutorial, the host application is written in JavaScript and runs inside a web browser.…
