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.

Preface

The Angular router module


All routing features in Angular 2 are available inside the angular2/router module. So if we load it inside the bootstrap-er we can access all of those features through any component in this project. The Angular 2 seed project has already provided the required configurations and we don't need to do anything. But to see how it is done, let's checkout the index.html file and follow the references over there. Open the index.html and notice the JavaScript files included there:

# index.html 
    <script src="polyfills.bundle.js"></script> 
    <script src="vendor.bundle.js"></script> 
    <script src="app.bundle.js"></script> 

The files we are interested in are vendor.bundle.js and app.bundle.js. It seems that they should be at the same place where index.html exists, but there is no sign of them.

We talked about what is happening here in Chapter 1,Setting Up the Environment. As a reminder, please keep in mind that .ts files should be...
