The Websocket Handbook 1st Edition Alex Diaconu by Alex Diaconu instant download after payment.

 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
messages, what kind of data can be sent over WebSockets, what types of extensions and
subprotocols you can use to augment WebSockets.
Chapter 3: The WebSocket API provides details about the constituent components of the
WebSocket API — its events, methods, and properties, alongside usage examples for
each of them.
Chapter 4: Building a Web App with WebSockets provides detailed, step-by-step
instructions on building a realtime web app with WebSockets and Node.js: an interactive
cursor position-sharing demo.
Chapter 5: WebSockets at Scale is an overview of the numerous engineering decisions
and technical trade-offs involved in building a system at scale. Specifically, a system that
is capable of handling thousands or even millions of concurrent end-user devices as they
connect, consume, and send messages over WebSockets.
Resources — a collection of articles, videos, and WebSocket solutions you might want to
explore.
The WebSocket technology is a vast and complex topic; this second version of the ebook
does not intend to cover everything there is to know about it. In future iterations, we plan
to:

 • Add more details to the existing chapters.

 • Provide more examples and walkthroughs for building apps with WebSockets. 

• Cover additional aspects that are currently out of scope, such as WebSocket security,
and alternatives to WebSockets
