WebSocket e-bog

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, youll 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. Youll also learn how to use WebSocket with Transport Layer Security (TLS).Learn how to use WebSocket API events, messages, attributes, and methods within your client applicationBuild bi-directional chat applications on the client and server with WebSocket as the communication layerCreate a subprotocol over WebSocket for STOMP 1.0, the Simple Text Oriented Messaging ProtocolUse options for older browsers that dont natively support WebSocketProtect your WebSocket application against various attack vectors with TLS and other toolsDebug applications by learning aspects of the WebSocket lifecycle
