Overview of this book

Are you are looking for a better, more efficient, and more powerful way of building front-end web applications? Well, look no further, you have come to the right place! This book comprehensively integrates Angular version 4 into your tool belt, then runs you through all the new options you now have on hand for your web apps without bogging you down. The frameworks, tools, and libraries mentioned here will make your work productive and minimize the friction usually associated with building server-side web applications. Starting off with building blocks of Angular version 4, we gradually move into integrating TypeScript and ES6. You will get confident in building single page applications and using Angular for prototyping components. You will then move on to building web services and full-stack web application using ASP.NET WebAPI. Finally, you will learn the development process focused on rapid delivery and testability for all application layers.

In AngularJS, we consumed services to retrieve data asynchronously using promises in $http. In Angular, we have the Http service over $http, and it returns an observable object instead of a promise as it applies a pattern called the analogous pattern. Angular leverages the Observable class adopted from the ReactiveX library. ReactiveX is an API for asynchronous programming with Observables that is done by applying the observer and iterator patterns and functional programming. You can find more information about Reactive programming at

Observer pattern will notify the dependents if their dependency object is changed. Iterator pattern will facilitate access to a collection without the need to know about the structure of the element in the collection. Combining these patterns in ReactiveX enables the observer to subscribe to an observable collection objection. The observer doesn't need to wait until the observable collection object is available. Instead, the...
