Programming WebAssembly with Grain: The Complete Guide to Building High-Performance Web Applications with Functional Programming
Programming WebAssembly with Grain: The Complete Guide to Building High-Performance Web Applications with Functional Programming
WebAssembly is transforming how applications are built for the web, servers, and beyond. Grain brings the power of functional programming to WebAssembly, making it easier for developers to write expressive, reliable, and high-performance applications.
This book is a complete guide to programming WebAssembly with Grain. It starts with the foundations of WebAssembly, then introduces Grain's syntax and functional programming model. Through practical examples and hands-on projects, you'll learn how to compile, run, and optimize Grain applications for both browser and server environments.
Inside you will learn:
The principles of WebAssembly and why it matters for modern development
How Grain fits into the WebAssembly ecosystem
Core Grain syntax, functions, data types, and control flow
Functional programming patterns such as immutability, recursion, and higher-order functions
How to compile Grain into efficient WebAssembly binaries
Interoperability between Grain and JavaScript
Deploying Grain applications to the browser, Node.js, and edge environments
Building real projects including games, CLI tools, and web applications
Debugging, testing, and optimizing WebAssembly modules
Best practices for packaging, publishing, and securing Wasm modules
Whether you are a web developer looking to boost performance, a systems programmer curious about Wasm, or a student exploring functional programming, this book provides everything you need to start building real-world applications with Grain and WebAssembly.
Take the next step in your development journey and explore the future of high-performance applications with Grain.
