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 Google Trends service


We can use Google Trends to gain some insight regarding which search keywords are trending in a particular region within a specific time span. This service that is packed with loads of visualized data provides you with valuable information about almost any keyword you choose.

Head to https://www.google.com/trends page and see the default page for these services:

Beneath the graphs there are an infinite loop of trending keywords, their related stories, and a snapshot of their trending graph over the past 10 years. This service does not limit you to the trending keywords of the moment and if you want to look for your OWN specific keywords and want to compare them to each other you can try the following query parameters (here we are comparing Clinton, Sanders, and Trump as an example):

https://www.google.com/trends/explore?date=all&q=Clinton,Sanders,Trump&hl=en-US

This will draw a couple of charts showing the result of those comparisons in multiple ways:
