The Storage Interface in SSVM

The SSVM storage interface provides a Rust API that allows programs to persist arbitrary data into a key value store. The data store is configured and started by the SSVM and hence is transparent to the Rust application. Rust developers can view this as an abstract storage space for application data. The storage interface provides much higher performance and data throughput than using WASI calls to access database on the file system or via network.…

🔐 Encryption and decryption

One of the frequently performed computing tasks is public key encryption and decryption. Rust and C++ code vastly outperforms JavaScript code in these tasks. In this tutorial, let's use pure Rust implementation of the RSA algorithm as an example to show how to perform public key encryption and decryption in a Node.js web service. In the getting started with Rust functions in Node.js, we showed you how to compile high performance Rust functions into WebAssembly, and call them from Node.…

🚀 Getting started with Rust functions in Node.js

There are great use cases for WebAssembly on the server-side, especially for AI, blockchain, and big data applications. In this tutorial, I will show you how to incorporate WebAssembly functions, written in Rust, into Node.js applications on the server. This approach combines Rust's performance, WebAssembly's security and portability, and JavaScript's ease-of-use. A typical application works like this. The host application is a Node.js web application written in JavaScript. It makes WebAssembly function calls.…

🛠 Set up Rust & WebAssembly in Node.js

There are great use cases for WebAssembly on the server-side, especially for AI, blockchain, and big data applications. You can write functions in Rust, compile into WebAssembly, and call the managed code in Node.js applications on the server. This approach combines Rust's performance, WebAssembly's security and portability, and JavaScript's ease-of-use. Docker setup The easiest way to set up your dev environment is to use Docker. First, clone the starter template project.…

🤖 Image recognition in Node.js

Deep learning is one of the most important advances in computer science in the last decade. Using trained deep neural networks, artificial intelligence (AI) inference algorithms can perform a variety of very useful tasks, such as image, speech, and facial recognition, natural language processing, image and video search, at unprecedented accuracy. While inference can be done on the edge device, such as mobile phones or IoT sensors, it is suggested that cloud-based inference is much faster and energy efficient in our always-connected world.…

How to Learn Rust Without Installing Any Software

In this article, we'll learn how to use GitHub Actions to learn Rust from your web browser. We'll code, build, test, run, and release all from a web page. No software needed! Learn with GitHub. Rust is one of the hottest programming languages today. Alpha geeks love it. It is Stackoverflow's most beloved programming language for the past 4 years in a row. One of the most unique and beloved features of Rust is its aggressive compiler that helps you ensure correctness and safety before the program even runs.…

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.…
