Programming with WASI Preview 2
"Programming with WASI Preview 2" "Programming with WASI Preview 2" is a comprehensive technical guide dedicated to the next generation of secure, portable, and interoperable application development using the WebAssembly System Interface (WASI) Preview 2. This book begins with foundational concepts, elucidating the core principles behind WebAssembly’s architecture and execution model, the historical evolution and motivations for WASI, and the pivotal technological advances introduced with Preview 2. Readers are provided with in-depth explorations of security principles, sandboxing models, and the new component model that empowers modularity and cross-language interoperability across diverse runtimes and toolchains. Central to this resource is its focus on practical application and multi-language development. The book covers the full spectrum of WASI Preview 2’s core APIs, such as advanced filesystem operations, networking, process management, cryptographic primitives, and robust environment configuration. Developers gain advanced strategies for building, packaging, and optimizing WASI applications for cloud, edge, and embedded scenarios, substantiated by real-world case studies and best practices. Rich content on debugging, testing, profiling, and continuous integration ensures that readers can deliver performant, production-ready systems with confidence. Beyond the technical mechanics, "Programming with WASI Preview 2" addresses the broader operational and ecosystem-level considerations, including multi-runtime deployments, secure software supply chains, and strategies for extending and contributing to the WASI specification itself. Whether you are an experienced systems engineer, a polyglot application developer, or an architect seeking to harness the latest advancements in WebAssembly, this book equips you with expert knowledge, actionable patterns, and a forward-looking understanding of the evolving universal compute platform powered by WASI Preview 2.
Building and Deploying WebAssembly Apps
DESCRIPTION WebAssembly is a groundbreaking technology that has transformed the way we build and deploy web applications. It enables lightning-fast performance, portability across platforms, and seamless integration with existing web technologies. This comprehensive guide will lead you through the journey of mastering WebAssembly, from its fundamentals to advanced applications. This book introduces WebAssembly basics, its purpose, and real-world use cases in web, server, and desktop apps. Featuring examples in languages like AssemblyScript, C/C++, and Rust, it covers converting legacy codebases to WebAssembly for browser compatibility. It showcases advanced use cases like WebAssembly-based music tools, Git integration, and smart contracts. The book concludes with WebAssembly's role in cloud-native Kubernetes, signaling a new era in container orchestration. Many of the examples build on the author's experience with WebAssembly Music, git in WebAssembly, and NEAR protocol smart contracts. These examples serve as real-world use cases, more than just a basic introduction to the technology. By the end of this book, you will have gained the knowledge and skills to confidently build, deploy, and optimize high-performance WebAssembly applications across a wide range of platforms and use cases.
