Programming with Grain for WebAssembly

"Programming with Grain for WebAssembly"
"Programming with Grain for WebAssembly" is a comprehensive guide that explores the intersection of modern functional programming and high-performance WebAssembly applications. The book begins with a deep dive into the Grain language, examining its roots in the ML family, its robust static type system, and advanced features such as algebraic data types, pattern matching, and immutability. Readers will gain a solid foundation in the principles and paradigms that make Grain a powerful tool for writing safe, modular, and expressive code targeting WebAssembly.
Moving beyond the language's core, the book unpacks the intricacies of the WebAssembly architecture, delineating its binary format, stack machine semantics, system interfaces (WASI), and threading model. It offers a detailed walkthrough of the Grain-to-WebAssembly compilation process, emphasizing functional optimizations, debugging strategies, and cross-compilation for diverse deployment targets. Readers will also learn practical techniques for seamless Grain integration with JavaScript and host environments, including data marshalling, efficient boundary crossings, and access to browser and Node.js APIs.
Throughout its chapters, the book addresses critical topics such as performance optimization, concurrency, security, and portability. It equips readers with advanced knowledge for profiling, memory management, and securing their applications against modern threats. With dedicated sections on tooling, workflow, and developer experience, along with forward-looking perspectives on non-web targets, ecosystem growth, and future research, "Programming with Grain for WebAssembly" serves as both an authoritative reference and an inspiration for engineers building the next generation of web and cloud-native systems.
