Reactive Publishing

WebAssembly is changing how software is built, deployed, and executed across platforms. WebAssembly Engineering with Rust, C++, and WASI is a practical guide for developers who want to understand how WebAssembly fits into modern application architecture, systems programming, and portable software design.

This book introduces the core concepts behind WebAssembly, then moves into hands-on development using Rust, C++, and the WebAssembly System Interface. Readers will learn how WebAssembly modules are compiled, structured, executed, and integrated into larger software systems.

Inside, the book covers WebAssembly fundamentals, toolchains, module design, memory handling, interoperability, WASI-based execution, runtime environments, and practical deployment considerations. It also explores how WebAssembly can support portable application development across browsers, servers, edge environments, and embedded-style execution contexts.

Written for software engineers, systems programmers, backend developers, and technically minded programmers, this book provides a structured path into WebAssembly without relying on hype or vague claims. It focuses on clear engineering principles, practical implementation patterns, and the tradeoffs developers need to understand when working with WebAssembly in real-world projects.

WebAssembly Engineering with Rust, C++, and WASI is designed for readers who want to build a strong foundation in portable software systems and understand how WebAssembly connects with modern programming workflows.
