Overview of this book

A primary concern with modern day applications is that they need to be dynamic, and for that, data access from the server side, data authentication, and security are very important. Angular leverages its services to create such state-of-the-art dynamic applications. This book will help you create and design customized services, integrate them into your applications, import third-party plugins, and make your apps perform better and faster. This book starts with a basic rundown on how you can create your own Angular development environment compatible with v2 and v4. You will then use Bootstrap and Angular UI components to create pages. You will also understand how to use controllers to collect data and populate them into NG UIs. Later, you will then create a rating service to evaluate entries and assign a score to them. Next, you will create "cron jobs" in NG. We will then create a crawler service to find all relevant resources regarding a selected headline and generate reports on it. Finally, you will create a service to manage accuracy and provide feedback about troubled areas in the app created. This book is up to date for the 2.4 release and is compatible with the 4.0 release as well, and it does not have any code based on the beta or release candidates.

What is a module?


The short answer is: every class you create in Angular is a module. The contents of a module could be anything. It could be a component, a service, a simple piece of data, and even they could be a library of other modules. They might look different, but they share one purpose: modules bring (export) one piece of functionality to the Angular projects.

Note

Creating Angular projects in a modular fashion makes the testing and maintenance tasks easy and helps the scalability in the future. However, you are not limited to an Angular modular approach and you can use your own style.

Later in this chapter, we will see that there is an export keyword in front of each class keyword:

export class MyClassName{} 

This is how Angular shares the logic inside that module (class) with the rest of the project. To use this module in other parts of a project, we just need to import it. Imagine the preceding code is saved inside a file named: myclassname.ts. To use that module in another module...
