Preface

Do you want to build resilient online apps that delight and satisfy users, regardless of the network state? Do you want to learn about frameworks that make cross-device synchronization easy? Do you need to communicate the value and efficacy of designing for everyone and not just people with a fast, reliable Internet connection?

If so, this book is for you. We'll start by talking about the realities of poor and non-existent Internet connections, then develop an offline app using Sencha Touch, and gradually convert it to a fully functional online experience that retains the robustness of its offline roots. You'll learn valuable tips and techniques that you can use in your own projects.
