WebAssembly & Rust

Supercharge Your Web Apps with Native Speed.
If you've hit the limits of JavaScript and crave more power, precision, and performance in your web applications, it's time to harness the full potential of WebAssembly (Wasm) and Rust.
WebAssembly & Rust is the practical, hands-on guide that shows you how to build lightning-fast web applications by combining the safety of Rust with the raw performance of Wasm-bringing systems-level programming to the browser.

This book walks you through building real, interactive apps that compile Rust into WebAssembly and run natively in modern browsers. You'll learn how to optimize critical performance paths, interoperate with JavaScript, and deploy Wasm modules that unlock next-gen web capabilities.

No more sluggish frontend bottlenecks. No more compromising performance for convenience. With this guide, you'll write low-level code that runs fast, runs safe, and runs everywhere.
