Improving Node.js performance using Rust

This article explores how to enhance Node.js applications by leveraging Rust, focusing on two primary methods: Node.js native addons using Node-API and the Foreign Function Interface (FFI). Node.js, a popular JavaScript runtime, is efficient for API consumption but can struggle with heavy computational tasks due to its single-threaded nature. Rust, known for its speed and concurrency capabilities, can be integrated to improve performance. The article details setting up projects using Neon for Node-API and FFI, demonstrating how to write Rust functions that can be called from JavaScript. While Node-API addons are typically faster, FFI provides a straightforward way to call Rust code from Node.js. The guide provides a foundational understanding for integrating Rust and Node.js, encouraging further exploration of libraries like nodejs-sys, node-bindgen, and napi-rs for more complex implementations.
