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.

A word on REST


Representational State Transfer (REST) is an architecture style that exposes data and functionality using Uniform Resource Identifiers (URIs). It is independent of protocol or message format. Most web applications use RESTful web services over HTTP using JSON as the message format. The RESTful web services over HTTP use the following convention when mapping CRUD operations to HTTP methods:

CRUD operation

HTTP method

Create

POST

Read

GET

Update

PUT

Delete

DELETE

The RESTful web services are used in modern single page applications because they decouple the services from the user experience logic. They are also performant, lightweight, scalable, stateless, and maintainable.

The products grid application uses the RESTful web services to perform CRUD operations on the products. It exposes the following services:

Service description

HTTP method

URI

Message format

Add a product

POST

http://[host:port]/products

JSON

Retrieve all products

GET
