Overview of this book

Over the years, JavaScript has become vital to the development of a wide range of applications with different architectures. But JS moves lightning fast, and it’s easy to fall behind. Modern JavaScript Applications is designed to get you exploring the latest features of JavaScript and how they can be applied to develop high-quality applications with different architectures. Begin by creating a single page application that builds on the innovative MVC approach using AngularJS, then move forward to develop an enterprise-level application with the microservices architecture using Node to build web services. After that, shift your focus to network programming concepts as you build a real-time web application with websockets. Learn to build responsive, declarative UIs with React and Bootstrap, and see how the performance of web applications can be enhanced using Functional Reactive Programming (FRP). Along the way, explore how the power of JavaScript can be increased multi-fold with high performance techniques. By the end of the book, you’ll be a skilled JavaScript developer with a solid knowledge of the latest JavaScript techniques, tools, and architecture to build modern web apps.

Chapter 5. Bidirectional Communication in Real Time

We have been using COMET techniques to implement bidirectional communication between a web browser and web server. Long polling is the most popular technique of achieving bidirectional communication between a web browser and web server because it works without compromising user experience and without any extra server configuration, and it works on all web browsers that support AJAX. Long polling can easily be implemented in any existing HTTP server. But the problem with long polling and other comet techniques is that none of them are suitable for building real-time apps because of HTTP overhead. This means that every time an HTTP request is made, a bunch of headers and cookie data is transferred to the server, which in turn increases the latency, therefore making it unsuitable for creating applications such as multiplayer games, chat apps, social networks, and live score websites, which require bidirectional communication in...
