Overview of this book

KnockoutJS By Example is a project-based guide that introduces the key features and concepts of knockout.js. It helps you create an application skeleton and a Hello World application. You will develop a To-Do list application that aims to show the basic features of knockout.js in action, such as data binding and observables, following which you will develop a dynamic online customer registration form that captures and validates customer information. This book will further walk you through developing a customer banking portal, which demonstrates the use of knockout.js with components such as navigation bars, tabs, carousels, master details view, panels, forms, and wizards. You will also discover how to use token-based authentication and authorization to secure the customer banking portal, and move on to creating an editable products grid with CRUD operations. Finally, you will explore how to use the Google Maps API with knockout.js. KnockoutJS By Example will not only leave you with a basic understanding of knockout.js fundamentals but also take you through some of the advanced features. It will help you get a web application up and ready instantly.
