Programming WebRTC: Build Real-Time Streaming Applications for the Web

WebRTC is an API exposed in all modern web browsers. After almost a decade of development, the WebRTC specification was finalized, and this book provides faithful coverage of that finalized specification. You’ll start by building a basic but complete WebRTC application for video chatting. Chapter by chapter, you’ll refine that app and its core logic to spin up new and exciting WebRTC-powered apps that will have your users sharing all manner of data with one another, all in real time. No third-party libraries or heavy downloads are required for you or your users: you’ll be writing and strengthening your knowledge of vanilla JavaScript and native browser APIs.

You’ll learn how to directly connect multiple browsers over the open internet using a signaling channel. You will gain familiarity with a whole set of Web APIs whose features bring WebRTC to life: requesting access to users’ cameras and microphones; accessing and manipulating arbitrary user files, right in the browser; and web storage for persisting shared data over the life of a WebRTC call. Like any Web API, WebRTC doesn’t enjoy a perfect implementation in any browser. But this book will guide you in writing elegant code to the specification, with backward-compatible fallback code for use in almost all modern browsers.

Use WebRTC to build the next generation of web applications that stream media and data in real time, directly from one user to another—all by working in the browser.
