Who this book is for
This book is for web developers who want to get into the new paradigm of single-page, real-time applications. You don't need to be a JavaScript professional to follow along, but certainly a good basic understanding will make this book a valuable companion.
If you have heard about Meteor but haven't yet used it, this book is definitely for you. It will teach you everything you need to understand and use Meteor successfully. If you have used Meteor before but want to get a deeper insight, then the final chapter will help you improve your understanding of custom reactive objects and writing packages. Testing is probably the least covered topic in the Meteor community right now, so by reading the final chapter, you will easily gain an understanding of how to make your apps robust using automated tests.
