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.

Introduction to WebRTC


Web Real-Time Communications (WebRTC) is a browser technology that enables retrieval of media stream of physical media sources and exchange media stream or any other data in real time. It comprises of three APIs: the MediaStream constructor, RTCPeerConnection constructor, and RTCDataChannel interface.

In short, MediaStream is used to retrieve the stream of physical media source, RTCPeerConnection is used to exchange MediaStream among peers in real time, and finally, RTCDataChannel is used to exchange arbitrary data among peers.

Let's see how these APIs work.

MediaStream API

Two main components of MediaStream API are the MediaStream constructor and MediaStreamTrack interface.

A track represents the stream of a media source. A track implements the MediaStreamTrack interface. A track can either be an audio track or be a video track. That is, a track attached to an audio source is an audio track, and a track attached to a video source is a video track. There can be multiple...
