Summary:

Until recently, creating desktop-like applications in the browser meant using inefficient Ajax or Comet technologies to communicate with the server. With this practical guide, you’ll learn how to use WebSocket, a protocol that enables the client and server to communicate with each other on a single connection simultaneously . No more asynchronous communication or long polling! For developers with a good grasp of JavaScript (and perhaps Node.js), author Andrew Lombardi provides useful hands-on examples throughout the book to help you get up to speed with the WebSocket API. You’ll also learn how to use WebSocket with Transport Layer Security (TLS).
