Preface

Development of a big web application is a hard task. Because of this, people try to use different useful and flexible approaches to build the architecture of their applications. One such approach is Knockout.js. It is a JavaScript library that provides you with a sophisticated way to communicate between your UI and the underlying data model to create rich web user interfaces based on the Model-View-ViewModel (MVVM) pattern. Knockout.js provides a simple two-way data binding mechanism between your data model and UI, which means that any change to your data model is automatically reflected in the UI and vice versa. Instead of using pure Knockout.js, you can use Knockout MVC. It is a library for ASP.NET MVC, which is a wrapper for Knockout.js that helps to move the entire business logic to the server side; the complete JavaScript code necessary on the client side will be generated.

This book will provide you with the skills you need to successfully create a Knockout.js-based application of varying complexity, from a simple Knockout.js web page in pure JavaScript to a complex ASP.NET web application. You will learn how you can use the MVVM design pattern, including the dependency tracking system and observable properties for creation of powerful sites with a clear separation of model, logic, and view layers.
