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.

Summary


In this chapter, we started with the idea of gathering evidence which supports investigation into an article of our interest. We looked at how we can have a general evaluation for an article and how to measure, weigh down, and lift up the value of certain words in any article.

We learned how to see an article as a bag of words and how to use this concept to calculate similarity. We set up and used Custom Search Engine and Yahoo APIs to query and fetch the contents of Web pages in periodic time spans.

Finally, we learned how to get some insight by clustering the gathered articles - corpus - around specific subjects and we saw how to visualize the cluster using a third-party data visualization library (VisJs) and an Angular wrapper module (ng2-vis).

In the next chapter, we take one step back and try to organize what we have created so far into an informative report.
