🦀 Rust Functions in Node.js

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.js applications. With JSON support, JavaScript code can call Rust functions with any number of input parameters and return any number of return values of any type. That allows us to take advantage of a large number of Rust libraries and crates in the ecosystem.…

Getting started with Rust functions in Node.js with VSCode

In this tutorial, I will show you how to experiment with Rust and Node.js development without installing any developer tools software. Why do I want to write Rust functions in Node.js apps? There are several compelling reasosns. Performance, security, portability, and manageability are among the key reasons. Fork this GitHub repository to get started. In your fork, you can use GitHub's web UI to edit source code files.…

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.…

WebAssembly vs native code

WebAssembly aims to drastically improve your application performance, safety, and developer productivity. It replaces native code with a managed container and finely grained security model. Why do we program in native code in 2020? In the past several years, CPU speed has pretty much stopped improving. At the same time, AI, big data, and blockchain have all create huge demands for more computing power. So far, the solution has been more and more native code in our software.…

🚀 WebAssembly is the perfect runtime for server-side (or serverless) applications

In a recent paper on Science, MIT professor Leiserson et al. noted that, as Moore's Law stalled, “practically all industries will face challenges to their productivity”. But, while semiconductor miniaturization hits the quantum limit, the good news is that “there’s plenty of room at the top”. The drivers for growth will be from more efficient software, new algorithms, and specialized hardware. The paper demonstrated that machine learning tasks can run 60,000x times faster when we replace Python with native code and specialized hardware.…
