Why AngularJs Framework?
This article tells about why AngularJs
is the preferred JavaScript Framework by most of the Web developers for their
front-end web development. As, in present scenario consumers access websites
and web applications on a variety of devices, operating systems and browsers.
Therefore, developers have to pay a lot of attention to the website's user
interface (UI) so that it's easy to access, use and navigate. As a strong
client-side programming language, JavaScript helps developers to create rich
web user interfaces (UI). Developers can further enhance web UI design using
many front-end JavaScript frameworks but AngularJs is mostly preferred.
Like other open source javascript
framework, AngularJS also helps developers to reduce overall web application
development costs. But it triggers custom web application development by
enabling the programmer to express various components of the web application by
expanding the HTML syntax. Additionally, AngularJS updates the UI of the
web-application whenever the backend changes by supporting two-way data
binding. Developers can further extend it by integrating with various
JavaScript libraries. So, let’s know why the web developers prefer it more:
ü
Enhances the HTML syntax
As, in addition to being written in
JavaScript, AngularJS is also distributed as a JavaScript file. It can be
directly embedded in a web page through the script tag. In addition, it allows
developers to express HTML to various components of the web application by
expanding it with three ng-directives: - ng-app, ng-model and ng-bind. Web
Developers can use AngularJS Expression to bind AngularJS data to HTML without
writing additional code.
ü
MVC pattern is implemented differently
Model-View-Controller enables
developers to simplify the development of large web applications by isolating
their user interface and business logic. But AngularJS implements the MVC
pattern in a different way. The AngularJS team calls the different
implementation of MVC as Model-View-Whatever. Model-View-Whatever pattern makes
it easy for architecture programmers to improve performance and maintenance of
complex web applications.
ü
Two way data binding is supported
In addition to implementing the MVC
architecture individually, AngularJS also supports two-way data binding. This
feature helps developers to synchronize the data between model and view
components without additional effort. AngularJS automatically updates the web
application's frontend every time the web backend changes. As the AngularJS
model synchronizes and views automatically, developers do not need to implement
DOM manipulation.
ü
Improves the server communication
By supporting caching, AngularJS
significantly reduces web server load. Also, the built-in services provided by
AngularJS assist developers in improving client-server communication. Services
make it easy for web developers to work with various backend systems and
solutions. Also, developers can take advantage of the underlying services to make
the data return asynchronously without writing complex code.
ü
Enforce client-side form validation
Web developers can create different
types of forms with the combination of HTML, CSS and AngularJS. AngularJS helps
developers to implement client-side form validation. It tracks the status of
the form along with the individual text field. It also informs users about the
current state of the form or input field. Developers can easily validate form
input using the standard HTML5 features. AngularJS also allows them to write
and use custom verification tasks.
ü
Code remains maintenance and
testable
AngularJS helps developers to write
testable and maintainable code by expanding HTML syntax. In addition to
extending existing HTML tags, developers can use instructions to create custom
HTML syntax. Additionally, the Framework programmers keep code testable by
allowing the program to use JavaScript objects. The model in AngularJS is also
designed as plain JavaScript objects. Therefore, developers can use the
framework to write clean, readable, maintainable and testable codes.
ü
Provides an underlying dependency
injection subsystem
Frequently web developers use
dependency injection tools to inject the dependency on an object in the most
appropriate way and make the object exchange dependencies easily. AngularJS
simplifies dependency injection by providing the underlying dependency
injection subsystem. The dependency injection subsystem makes it easy for the
developers to replace different components from web applications along with the
display of performing testing.
ü
As a component of the MEAN stack
Most of the web developers prefer to
use AngularJs as a major component of
the MEAN stack along with MongoDB as a NoSQL database, Express.js and Node.js. As
a full-stack JavaScript, MEAN enables to write both client-side and server-side
code in JavaScript by the programmers. With more and more enterprises who
choose isomorphic applications, AngularJS is being widely used by developers as
a component of MEAN Stack.
ü
Many AngularJS-based frameworks
In addition to integrating AngularJS
with widely used JavaScript libraries, web developers also have the option to
avail many AngularJs based frameworks such as-Suave, PrimeNG, QuantumUI,
SemanticUI and UI Bootstrap. The UI components provided by these angular
JS-based frameworks make it easy for web developers to create custom web-based
user interfaces. In addition, these frameworks help the developers create
responsive and cross-browser web user interfaces.
ü
It keeps on evolving
As previously mentioned, AngularJS is
maintained by Google with the community of developers. Therefore, it is
constantly evolving to simplify and speed up web application development. In
November, the AngularJS 5 was released with many new features. The latest
version of the JavaScript framework simplifies the development of progressive
web applications, removes unnecessary code from the application via a build
optimizer, and provides a new HTTP client.
Conclusion:-
As a result, the features provided by
AngularJS help web application developers to create custom web UI in a short
span of time. But web developers should remember that like the other JavaScript
frameworks, AngularJS has its own professional and opposition. To accelerate
custom web application development, they need to integrate AngularJS with other
JavaScript libraries and frameworks. They can still use the latest version of
AngularJS to take advantage of the set of new and improved features.
