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.

Preface

Chapter 8.  The Accuracy Manager Service - Putting It All Together

The job of the accuracy manager is to deal with anomalies found after running the application. For example, from the previous chapter we ended with extreme results. In the report we found out that the longest article is almost as big as a 150 page book and the shortest has only five characters (null characters) in it. So the objective of this chapter can be summarized as follows:

  • We need to pin point those issues as soon as they show up (cure)

  • We have to make sure that they won't happen again in the future (prevention)

Let's talk about the nature of these two items and expand them a little.
