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.

The Accuracy Manager Wire-frame


We can not solidly rely on our AI component only. It is good to have a feedback mechanism to evaluate the result of our AI mechanism after a specific time-frame. When we get fresh news to investigate and find the answer to a fundamental question for that news, normally we need to wait for a couple of days (or week's maybe) for the truth to be revealed.

Then we can compare our AI results with the truth and find out how accurate our application is. After collecting the feedback, later we can decide what to do with it. We can tweak our current business log to achieve better results, for example, or we can add new pieces of logic and new mechanisms to catch all the missing parts and improve the quality of our application.

So the wire-frame for the Accuracy Manager is very simple: it looks for the same news for the given keywords after a specific time frame. If the new version of that news exists it notifies us and fetches a fresh copy of it. Then we can compare...
