The WebSocket Handbook (Alex Diaconu) (Z-Library)

Author： Alex Diaconu

Our everyday digital experiences are in the midst of a realtime revolution. Whether we’re talking about virtual events, EdTech, news and financial information, IoT devices, asset tracking and logistics, live score updates, or gaming, consumers increasingly expect realtime digital experiences as standard. And what better to power these realtime interactions than WebSockets? Until the emergence of WebSockets, the “realtime” web was difficult to achieve and slower than we’re used to nowadays; it was delivered by hacking existing HTTP-based technologies that were not designed and optimized for realtime applications. WebSockets mark a turning point for web development. Designed to be event-driven & full-duplex, and optimized for minimum overhead and low latency, WebSockets have become a preferred choice for many organizations and developers seeking to build interactive, realtime digital experiences that provide delightful user experiences. Who this book is for This book is intended for developers (and any other types of technical audiences) who want to: • Explore the core building blocks of the WebSocket technology, its characteristics, and its advantages. • Build realtime web apps with WebSockets. • Discover the benefits of event-driven architectures with WebSockets. • Learn about the engineering challenges you will face when building scalable systems with WebSockets. Knowledge of/familiarity with HTML, JavaScript (and Node.js), HTTP, web APIs, and web development is required to get the most out of this book. 07 The WebSocket Handbook Preface What this book covers Chapter 1: The Road to WebSockets looks at how web technologies evolved since the inception of the World Wide Web, culminating with the emergence of WebSockets, a vastly superior improvement on HTTP for building realtime web apps. Chapter 2: The WebSocket Protocol covers key considerations related to the WebSocket protocol. You’ll find out how to establish a WebSocket connection and exchange messa
