"Wagi in Practice"
"Wagi in Practice" offers a definitive exploration of Wagi, a groundbreaking runtime for executing WebAssembly modules in server environments. The book methodically guides readers through the architectural foundations of Wagi and its relationship with the WebAssembly System Interface (WASI), providing a thorough understanding of handler invocation, process isolation, and supported development toolchains. Insightful comparisons to other state-of-the-art server paradigms such as FastCGI and containerized microservices highlight Wagi's unique strengths in performance, portability, and security.
Delving into advanced application design, the book equips readers with proven patterns for handler orchestration, routing, and scalable state management. It addresses practical considerations including error propagation, observability, and automated testing, ensuring robust and maintainable Wagi applications. Chapters dedicated to security illuminate key attack surfaces, sandboxing strategies, authentication mechanisms, and compliance, making this resource invaluable for architects and developers building resilient production systems.
"Wagi in Practice" expands further to encompass key topics such as performance optimization, DevOps automation, and integration with diverse ecosystem components like databases, message queues, and API gateways. Real-world case studies—spanning edge deployments, SaaS platforms, and enterprise modernization—demonstrate Wagi's versatility at scale. Concluding with a forward-looking perspective, the book surveys ongoing research directions, community initiatives, and emerging standards, cementing itself as an essential reference for mastering WebAssembly server computing with Wagi.
