Building WebAssembly (Wasm) Applications: Master Cross-Platform Apps with Rust, Go, C++, and WASI; Edge, Cloud Development, Plugins, and Real-World Projects

By Nolan K. Selby and Everett J. Crowne

Unlock the Power of WebAssembly — Build Faster, Smarter, and More Secure Applications Across Every Platform

In the new era of high-performance computing, WebAssembly (Wasm) is transforming how developers build and deploy modern applications — from the browser to the cloud, from Edge devices to IoT systems.

Building WebAssembly (Wasm) Applications is your comprehensive, end-to-end guide to mastering this revolutionary technology. Whether you’re a Rust developer, a Go programmer, or a C++ engineer, this book teaches you how to compile, optimize, and deploy real-world WebAssembly applications that run blazingly fast, securely, and portably anywhere.

What You’ll Learn Inside

• The Fundamentals of WebAssembly: Understand Wasm’s architecture, binary format, and performance advantages over JavaScript.

• Hands-On Development: Write WebAssembly by hand using .wat, build and run modules, and learn to optimize memory, threading, and performance.

• Multi-Language Integration: Compile and connect Rust, Go, and C++ code into Wasm for seamless cross-platform workflows.

• WASI and Beyond: Explore the WebAssembly System Interface, unlocking file system, networking, and CLI capabilities — running Wasm outside the browser.

• Edge and Cloud Deployment: Deploy Wasm at scale using Cloudflare Workers, Fastly, and serverless computing environments.

• Frontend Framework Integration: Integrate Wasm modules into React, Vue, Svelte, and TypeScript projects using Webpack, Vite, and Parcel.

• Performance Optimization and Benchmarking: Compare Wasm vs. native JavaScript speed, use SIMD, multithreading, and profiling tools for real-world improvements.

• Advanced Security and Plugin Systems: Build sandboxed WebAssembly plugins, manage memory permissions, and run untrusted third-party code safely.

• Real-World Projects
