Modern JavaScript Applications

By: Narayan Prusty

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 3. Communication between Browsers in Real Time

To implement features such as audio/video chat or some other features in websites that require real-time peer-to-peer (browser-to-browser) data transfer, or need to retrieve audio/video stream from a microphone, webcam, or any other device, we had to use browser plugins such as Java and Flash. There are various issues with making websites depend on browser plugins, such as mobile browsers not supporting plugins and plugins requiring to be kept up to date. Therefore, WebRTC was introduced to solve these problems, that is, browsers that support WebRTC provide APIs to exchange data in real time directly between browsers and also retrieve stream from physical media sources without the use of plugins. In this chapter, we will discuss WebRTC and also the PeerJS library that wraps the WebRTC APIs to provide an easy to use API to work with WebRTC.

In this chapter, we'll cover the following topics:

  • Discussing various APIs provided by WebRTC

  • Retrieving...
