Introduction to AngularJS | AngularJS Examples For Beginners

I recently read the book on AngularJS of Novatec, the Introduction to AngularJS – A guide to developing with AngularJS, and then decided to do a review of it here. But before talking about the book, let’s first understand what is AngularJS.

AngularJS is an open-source JavaScript framework, which is handling by Google, which helps single-page applications run. Your goal is to increase applications that can be accessed by a web browser, under the model-view-controller pattern (MVC) in an effort to facilitate both the development and testing of applications.




The library reads the HTML that contains special tags and then executes the policy where it belongs tag, and makes the connection between the presentation and its model, represented by variables common JavaScript. The value of these JavaScript variables can be set manually or via a static or dynamic JSON feature.

The AngularJS is built on the belief that declarative programming is better than imperative programming when it comes to building user interfaces and component software connection, while the imperative programming is excellent for writing business rules. 1 The framework adapts and extends the traditional HTML for a better experience with dynamic content, with direct and two-way connection of data (two-way data-binding) that allows automatic synchronization of models and views. As a result, AngularJS abstracts the handling of DOM and improves testing.

Goals:

Abstracting application logic of the DOM manipulation. This improves code tests.
Considers the application as important tests for its development. The difficulty of the test is directly affected by how the code is structured.
Abstract coupling between the client side and the server side application. This allows the application development evolve on both sides, parallel to, and allows the reuse of code.
Guide developers through building the entire application: from the interface design, through the writing of business rules, until the implementation of the tests.

Angle follows the MVC pattern of software engineering and encourages the low coupling between presentation, data and logic components. Using dependency injection, Angled back services commonly assigned next application server, such as controllers for visual components for the application client side. Consequently, the weight of the backend is radically reduced, leading to much lighter applications.
The book

Introduction to AngularJS was written by Ken Williamson , he is an engineer and software architect , and has over twenty years of experience. Designed and implemented software for mobile devices, desktop and servers for some of the largest companies in the world . It is the creator of several open source projects , including Ulbora CMS .

The book consists of 12 chapters and they are listed below:

Introduction to AngularJS
The IDE and AngularJS projects
The MVC and AngularJS
Controllers AngularJS
Visions of AngularJS and Bootstrap
The AngularJS and REST services
Models AngularJS
Services and business logic
the AngularJS directives
Security in AngularJS
MEAN cloud and mobile applications
AngularJS and SEO

Introduction to AngularJS

Here not much to be discussed, the book begins with a basic overview of the AngularJS .
The IDE and AngularJS projects

This chapter focuses on helping you set up a HTML5 development environment using the NetBeans ( But it is to the user to use the editor you want) . Shows you how to download the latest versions of AngularJS , jQuery and Twitter Bootstrap and add them to the sample project . It also shows how to perform unit tests with JsTestDriver , Karma and overview of End to End testing using the protractor .
The MVC and AngularJS

As the chapter name suggests, it is all focused on MVC and makes comparisons of applications using front AngularJS other applications using other conventional server-side frameworks.
Controllers AngularJS

It explains how the Controllers in AngularJS and teaches how to perform basic unit testing each controller .

Visions of AngularJS and Bootstrap

This is where you learn how to create views using Twitter Bootstrap , and gives the start the tests with Karma and Protractor for the blog project that is set up throughout the book.
The AngularJS and REST services

The author teaches here as Angle works with REST services.
Models AngularJS

Remember the blog project I spoke that is created by the course of the book? This is where you add REST services to maintain a functional blog in the cloud. In addition you will learn how to write unit tests and End to End to test your REST services.
Services and business logic

Here is where you will learn everything you need to work with authentication REST services. More security issues are described in later chapters.

the AngularJS directives

Learn the basics on how to implement policies in Angle and implement a custom menu in policy-based blog design .
Security in AngularJS

several questions about security in AngularJS applications are discussed .
MEAN cloud and mobile applications

Learn here how to create an App with MEAN ( MongoDB , Express, Angle and Node) and host it in the cloud. Learn also how to port your application to mobile devices.
AngularJS and SEO

There is still a lot of people who think that Google does not read JavaScript. The book demystifies it and shows how an AngularJS application to be indexed by Google is possible.

Buy or not the book ?

This book is highly recommended for those who want to learn AngularJS . So if you know JavaScript and want to venture into AngularJS , do not waste time , it is a great investment , especially with 20 % discount using the code PINCELADASDAWEB in the cart.
