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.

Migration process

AngularJS and Angular differ syntactically and conceptually. So the migration process involves code change not only on a syntactical level but also in implementation. The Angular team made the life of the developers easier by providing built-in tools in Angular for migrating AngularJS applications to Angular. There is some preliminary process to do in our existing AngularJS applications before starting up the migration process.

The preliminary process involves decoupling the existing code and making the existing code maintainable. This preliminary process not only prepares the code for upgradation, but will also improve the performance of the existing AngularJS applications.

We can follow an incremental approach by running both AngularJS and Angular in the same application and initiate the migration process one by one starting from the components. This approach...
