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 template

We know that we are going to start with word instances and their counts and later on we are going to add more calculations to it. So let's create a table structure and add columns to it as we proceed.

Open the evidence.html file and modify its contents as follows:

# src/app/evidence/evidence.html 
<div class="col-md-6"> 
  <div class="panel panel-default "> 
    <!-- Default panel contents --> 
    <div class="panel-heading">Processing words</div> 
    <!-- Table --> 
    <table class="table"> 
        <th>#</th><th>Words</th><th>Raw Value</th> 
      <tbody *ngFor="#w of evidenceService.words; #i=index">
