Chapter 1, AngularJS Rationale and Data Binding, talks about why AngularJS is needed and why you should choose AngularJS over other client-side/server-side frameworks. It also talks about data binding, shows a simple Hello World application, and an application that demonstrates two-way data binding.

Chapter 2, Working with Data, talks about the whys and hows of dependency injection in Angular. Then it talks about filters and promises and finally shows you how to do Ajax communication using $http and $resource services.

Chapter 3, Custom Controls, is all about directives. It shows how you can write custom elements, attributes, and so on, and also talks about isolate scopes, transclusion, and other stuff about directives.

Chapter 4, Firebase, talks about different types of persistence mechanisms and local versus hosted databases. It then talks about the value proposition of Firebase and discusses AngularFire. Finally, it shows how to structure data while using Firebase and also talks about denormalization.

Chapter 5, Getting Started with AngularFire, shows how to use AngularFire. It shows synchronized objects and arrays and also shows three-way data binding in action.

Chapter 6, Applied Angular and AngularFire, builds an example application that shows how to use Firebase's anonymous authentication. It shows the difference between Angular factory and service, which is a commonly confused topic. It also uses Angular best practices in the example application.

Appendix A, Yeoman, demonstrates the use of yo (for scaffolding), grunt, and gulp (for building) and bower (for dependency management) tools. It discusses the advantage of using these tools and also shows how to install them using Node Package Manager (NPM).

Appendix B, Git and Git Flow, introduces Git which is one of the most widely used version control systems today. It shows the most basic Git commands to help you get started with Git quickly. It also shows simple Git branching and merging, and introduces Git flow—a tool which prescribes a practical branching model and makes branching and merging a joy.

Appendix C, Editors and IDEs, talks about editors and IDEs that have good support for web (HTML, CSS, and JavaScript) development technologies. The obvious candidates are Visual Studio, Eclipse, and Sublime Text and oldies such as Emacs and Vim. It also highlights the support for AngularJS in Brackets (backed by Adobe) and WebStorm (by JetBrains).

All that you need for the examples in this book is a good text editor that has support for HTML/JavaScript syntax highlighting and any modern PC/Laptop.

This book helps beginner-level AngularJS developers to organize AngularJS applications by discussing important AngularJS concepts and best practices. If you are an experienced AngularJS developer, but haven't yet written directives or created custom HTML controls, then this book is ideal for you. This book also shows you how to build real-time apps using Firebase/AngularFire to store and sync data in real time.

In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "We loaded the ngRoute module as a dependent of the routeApp module."

A block of code is set as follows:

'use strict';
app.service('employeeSvc', function () {

  var Employee = function (name, age) {
    this.name = name;
    this.age = age;
  };

Var getEmployees = function () {
    return [
      new Employee("First employee", 56),
      new Employee("Second employee", 44),
      new Employee("Last employee", 32)
    ];
  };

  // Public API
  this.Employee = Employee;
  this.getEmployees = getEmployees;
});

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

<br>
<div>
  <h1>Employee data:</h1>
  <ul>
    <li ng-repeat="employee in employeeData.employees">
      Employee - {{employee.name}} is - {{employee.age}} years old
    </li>
  </ul>
</div>

Any command-line input or output is written as follows:

bower install underscore

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "For other extensions, the Install button is enabled."
