Misko Hevery and Adam Abrons developed AngularJS initially in 2009. Later on, supported by Google 2010.

AngularJS is an open source framework. It means its original source code is freely available to all. Anyone can access its code as well as can make changes in it too. It works on a client side.

3. AngularJs Versions

Since variation becomes a part of today’s world. Similar in technology on a daily basis some upgradation is taking place to introduce some new features so that it makes more easy for a developer to code hence making the technology more efficient and powerful.

4. Why AngularJS?

AngularJS market in the world is rapidly growing. People are opting for its certification and courses more and more. The growth in a career in web development is increasing its graph day by day.

In this session of AngularJS tutorial, we will learn the major reason for evolving rapid increase of use of Angularjs:

  • Angular JS is used to make the HTML page as dynamic. By using angular one can convert the static page (a page that does not change except if changes are made by manually in its code) into a dynamic page as it extends the functionality of HTML elements.
  • It helps to make a single page application. It means content gets dynamically written on the page. A User need not require to refresh the page also the control will also remain on the same page it does not get transfers to another page.

5. Features of AngularJS

In this part of the AngularJS tutorial, we will cover a list of AngularJS features:

AngularJS Tutorial - Features of AngularJS

AngularJS Tutorial – Features

i. Not browser specific

It can run on all major browsers except internet explorer 8.0 and smartphones including Android and ios based phones/tablets.

ii. Code Less

A programmer has to write less and can perform more functionality with the same code.

iii. Productivity

A user interface is created in a simple way and that too fast also because of strong template syntax.

iv. Speed and performance

Speed is fast as angular apps code loads quickly due to code splitting.

v. Dependency Injection

This built-in injection helps in developing the application easily as well as it is easy to understand.

v. Deep Linking

It allows bookmarking the web page. The page gets saved by its URL without getting its state change.

vi. Routing

Routing allows the switching between views.

6. AngularJS Apps

7. Architecture of AngularJS

The angular framework is based on MVC architecture abbreviated as Model View Controller.

  • Model: It consists of the data of the application. Request made from the view part is handled by it.
  • View: Presentation layer represents by a view part. The user interaction is done with a view. Display task is done by view part.
  • Controller: The linking between the model part and view part handled by the controller. It receives input and then verifies it after that perform the operation to modify the state of the data model.

8. Components/Building Blocks of AngularJS

AngularJS components are considered as the building blocks. It is a small unit which we use to build an application. Components also define as a small code to create an application.

The component in AnuglarJS consist of the following elements:

  • Template
  • Class
  • Metadata

i. Template

The template is the part that contains directives and binding. HTML part is rendered using a template.


<HTML code>
class properties

ii. Class

It is the same as defined in other programming languages such as c++ , Java Class etc. It contains data member, methods, typescript that define the class.


class classname {
Propertyname: PropertyType = Value

The class is the keyword to define a class.

Classname is the name given to that class.

The Property name is the name of a data member that a class can contain. A class can contain multiple properties.

Property type defines the type of value property is holding.

Value is the data that a particular property specified in a class can hold.

iii. Metadata

Metadata is like a repository of details about a data. Decorator defines the metadata.

An Angular code is easy to unit test as there is an inbuilt dependency injection comes in it which makes it easier to test individual components of the code. As well as, it supports both unit testing and integration testing.

b. Limitations of AngularJS

  • Less Secure

It is not secure because there is no server authorization and authentication in angular so one cannot verify the identity in it. Security is one of the major concerns in today’s world technology is expanding rapidly so as the security concerns as it is necessary that your data should remain secure.

  • Only Emphasize on Javascript

AngularJS does not support internet explorer 8.0.

11. AngularJs Future Scope

Angular is among one of the mean stack technology and it is among one of the latest technology and easy to learn. Many IT companies are working on it as it makes web application development much efficient and powerful. Single page application is the future of web application learning it will definitely give growth to your career.

After being supported by Google many top companies SalesForce, Amazon-like started using angular. This is because angular provides an efficient and reliable solution to complex problems as well as it takes less time to develop software, efforts, get reduced while making it.

v. Routing

Routing allows the switching between views.

So, this was all about AngularJS tutorial. Hope you liked our explanation.
