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.

WebRTC applications using PeerJS


PeerJS is a client-side JavaScript library that provides an easy-to-use API to work with WebRTC. It only provides an API to exchange MediaStream and arbitrary data between peers. It doesn't provide an API to work with MediaStream.

PeerServer

PeerServer is an open source signaling server used by PeerJS to establish a peer-to-peer connection. PeerServer is written in Node.js. If you don't want to run your own PeerServer instance, then you can use PeerServer cloud, which hosts PeerServer for public use. PeerServer cloud allows you to establish a maximum of 50 concurrent connections for free.

A unique ID identifies every peer connected to PeerServer. PeerServer itself can generate the ID, or else the peers can provide their own ID. For a peer to establish a peer-to-peer connection with another peer, it just needs to know the other peer's ID.

You might want to run your own PeerServer instance when you want to add more functionality to PeerServer or you want to support...
