A Gentle Introduction to WebAssembly in Rust (2025 Edition) - DEV Community

So in this guide we’ll walk through setting up the tooling and development environment for building and using WebAssembly in Rust, embedding it in a TypeScript project, review how communication between TypeScript and Rust can happen, then finally how you can debug your WebAssembly directly in the browser and/or your favorite IDE. I will use Visual Studio Code as the IDE and Chrome as the browser, but apart from some debugging options, you can reproduce these in your tool of choice.
