Overview of this book

Got some experience of Angular under your belt? Want to learn everything about using advanced features for developing websites? This book is everything you need for the deep understanding of Angular that will set you apart from the developer crowd. Angular has introduced a new way to build applications. Creating complex and rich web applications, with a lighter resource footprint, has never been easier or faster. Angular is now at release 4, with significant changes through previous versions. This book has been written and tested for Angular release 4. Angular is a mature technology, and you'll likely have applications built with earlier versions. This book starts by showing you best practices and approaches to migrating your existing Angular applications so that you can be immediately up-to-date. You will take an in-depth look at components and see how to control the user journey in your applications by implementing routing and navigation. You will learn how to work with asynchronous programming by using Observables. To easily build applications that look great, you will learn all about template syntax and how to beautify applications with Material Design. Mastering forms and data binding will further speed up your application development time. Learning about managing services and animations will help you to progressively enhance your applications. Next you’ll use native directives to integrate Bootstrap with Angular. You will see the best ways to test your application with the leading options such as Jasmine and Protractor. At the end of the book, you’ll learn how to apply design patterns in Angular, and see the benefits they will bring to your development.

Summary

In this chapter, we learned about directives and also about different types of directives, namely Component Directives, Structural Directives, and Attribute Directives.

We implemented custom user-defined directives to understand how we can extend directives and use them more effectively.

We learned briefly about ZoneJS, and how zones can help us to handle the async tasks in modern applications frameworks.

Finally, we learned how Angular handles changes detection and how we can use change detection methods to improve the overall application performance.

In the next chapter, we will learn about asynchronous programming using Observables. In this chapter, we will learn how to take advantage of asynchronous programming with Angular by using Observable and Promises.

In addition, we will learn how to built a basic, yet extensible asynchronous JSON API for querying the Marvel...
