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.

How to choose a subject for a road test

But the reason that I'm going to choose an independent link as the subject of our investigation is because I can not trust the hot trends or mainstream media any more. As I mentioned earlier in this chapter, as part of the R&D for the Sherlock Project, I had to watch closely the news agency outlets and follow all the pulses when an important news story breaks out. At the same time, I watched how trends respond to news on an hourly basis. And finally, I watched how our application works with the given data.

I encourage everyone to do some experiments with a couple of hot trends and see it for yourselves. When I followed what was suggested by news agencies and supported by hot trends, I expected some insights which would give me a better understanding about...
