In this wasm rust tutorial, you’ll learn how to build blazing-fast web applications using Rust and WebAssembly (WASM). You’ll start from installing rustup and wasm-pack, walk through hello_wasm setup, and see Rust functions called directly from JavaScript in the browser. Discover how wasm-bindgen bridges UTF‑8/UTF‑16, compare performance trade-offs, and learn best practices for real-world Rust + WebAssembly integration. Very basic WebAssembly demo to start with! Whether you're a web developer, a Rust beginner, or exploring WebAssembly for performance, this video walks you through everything you need to know. 🚀 What You'll Learn What is WebAssembly (WASM) and how it works in modern browsers Why use Rust for WebAssembly instead of JavaScript or C++ Step-by-step WASM tutorial: Compile Rust to WebAssembly How to use wasm-pack and set up the Rust WebAssembly toolchain Creating your first Rust WASM project from scratch Using wasm-bindgen to bridge Rust with JavaScript (JS) How to call Rust functions from JavaScript Converting between UTF-8 and UTF-16 in WebAssembly Comparing Rust vs JavaScript performance in the browser How to run Rust in the browser using HTML + JS Full Rust WASM development workflow, explained clearly Serving a WebAssembly app over HTTP with simple tools 🛠️ Tools You'll Use rustup for installing Rust wasm-pack for compiling Rust to WASM wasm-bindgen for Rust ↔ JavaScript interop Basic http-server to run your app locally Chapters: 00:00 Introduction 00:27 Key Concepts 00:46 What is WebAssembly 01:27 Why use Rust For WebAssembly 01:47 What is Rust? 02:25 Why Rust and WebAssembly are an awesome combo 02:45 WebAssembly toolchain with Rust 04:39 Installing Rust Toolcahain 07:12 Creating Rust Project 11:30 Compiling our Rust code with wasm-pack 12:20 Using compiled project in HTML/JavaScript 14:07 Serving WASM Rust project over http 14:56 WASM Rust project workflow explained 👨‍💻 Who This Is For Frontend developers looking to explore Rust for web development Beginners seeking a WebAssembly tutorial using modern tools Anyone curious about how to build web apps with Rust and WASM Developers interested in Rust performance and JavaScript integration Related: Article version (with code): @a1guy/rust-webassembly-build-your-first-browser-app-without-emscripten-c92538728441?sk=98a9ea1bdada498c376cc8cdbafa607d #wasmrust #webassembly #rustprogramming #wasmtutorial #webdevelopment
