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.

Saving objects in a database


When it is about database related Angular apps, traditionally MEAN stack (MangoDB, Express, Angular, and Node) comes to mind. It is still a great choice, but there has been way better options provided by Google recently.

In this book, we are going to use Firebase. Firebase is a cloud platform for implementing web and mobile applications, which is packed with all you might need to develop, grow, and monetize applications.

What we are going to use in this chapter is the Firebase Realtime Database. It is realtime because it is a NoSQL database, where the moment you push a new JSON object to it, the new object will show up in the database and the moment you make any changes on the database itself, the change will be appear on the application instantly.

It is like the two-way data binding that we talked about earlier in this chapter, but way better. Some developers believe it is a three-way data binding, because Firebase is like a glue between Angular and DOM. Let's...
