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 Evidence Tree Builder Wire-frame

As part of investigation, we need to collect the evidence related to the article of our interest. The tricky part is how much evidence are we willing to collect?

Search any keywords in Google and you will get zillions of results. Obviously we don't want to include all of them. We need a business rule to filter out the irrelevant results and choose - let's say - up to 10 relevant evidences for each main node and five evidences for each branch. It is totally up to us how deep we want that tree to be. But let's start simple and add more complexity to it as we proceed.

We need to persist the nodes and branches to the database, and before that we need to create a specific document that can handle all relevant evidence. These will all be defined as child services for this component.

The other important factor here is showing the results in an interactive way. All inspectors used to have an investigation board that they pinned the related photos, papers, and so...
