One of the most useful features of today’s modern browsers is the ability to store data right on the user’s computer or mobile device. Even as more people move toward the cloud, client-side storage can still save web developers a lot of time and money, if you do it right. This hands-on guide demonstrates several storage APIs in action. You’ll learn how and when to use them, their plusses and minuses, and steps for implementing one or more of them in your application. Ideal for experienced web developers familiar with JavaScript, this book also introduces several open source libraries that make storage APIs easier to work with. Learn how different browsers support each client-side storage API Work with web (aka local) storage for simple things like lists or preferences Use IndexedDB to store nearly anything you want on the user’s browser Learn how support web apps that still use the discontinued Web SQL Database API Explore Lockr, Dexie, and localForage, three libraries that simplify the use of storage APIs Build a simple working application that makes use of several storage techniques

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
