This book has exposed us to different technologies for fast application development. We have seen enhancements of HTML5; we learned how WebSockets works. We have developed some applications based on HTML5 and WebSockets. WebSockets is one of the best methods of communication which provides some great features, such as full-duplex communication which allows the client as well as the server to push the data. We understood how Node.js-based servers can be very useful and easy to implement along with WebSocket server. We achieved and saw different examples of full-duplex communication using WebSockets. We got some exposure to different JavaScript-based libraries which provide readymade components for us to use. We have also seen WebSockets work on mobile devices and seen and understood the different mobile web design features of HTML5. And finally, we have seen different tools and techniques that can help in accelerating the development process of an application. The techniques not only...
