HTML5 is not just a replacement for plugins. It also makes the Web a first-class development environment by giving JavaScript programmers a solid foundation for building industrial-strength applications. This practical guide takes you beyond simple site creation and shows you how to build self-contained HTML5 applications that can run on mobile devices and compete with desktop apps.

You'll learn powerful JavaScript tools for exploiting HTML5 elements, and discover new methods for working with data, such as offline storage and multithreaded processing. Complete with code samples, this book is ideal for experienced JavaScript and mobile developers alike. Store session data in the browser with local storage objects Save trips to the server: store larger amounts of data with IndexedDB Give browsers limited access to a user's system to read and upload files Take your app offline--and speed up page loading when it's online Use Web Workers to create multithreaded applications Transfer data between browser and server more efficiently with Web Sockets Learn about HTML5 tags for forms, multimedia, graphics, and geolocation

"HTML5 is all the rage these days, but it's more than just a buzzword. "Programming HTML5 Applications" provides the knowledge to guide you through all the new technologies needed to make modern web applications." --Ralph Whitbeck, cohost of The Official jQuery Podcast

Why choose Erlang for web applications? Discover the answer hands-on by building a simple web service with this book. If you're an experienced web developer who knows basic Erlang, you'll learn how to work with REST, dynamic content, web sockets, and concurrency through several examples. In the process, you'll see first-hand that Erlang is ideal for building business-critical services.

Erlang was designed for fault-tolerant, non-stop telecom systems, and building applications with it requires a large set of skills. By the end of the book, you'll have the information you need to build a basic web service and get it running. Explore the power of Erlang and REST for building web services Serve static and dynamic content with the Yaws web server Use different methods for outputting data to user, such as encoding Erlang data structures into JSON or XML Build an application to listen for HTTP requests, process them, store data, and return useful data Go beyond the request-response model--push data to clients with web sockets Use Erlang and Yaws to stream data from the server to a client

"A book which is truly needed and will help get Erlang to the next level." --Francesco Cesarini, CEO of Erlang Solutions, author of Erlang Programming.
