Why Use AngularJS for Responsive Web Application Development?

It is a collectively concurred thought that organisations today have gotten increasingly advanced to encourage development. Everyone needs to play around with a lump of income from a digital presence.

With a monstrous number of sites now on the web, each spending day just brings more sites on the web. As a result, the need to have easy-to-understand and intelligent web applications is getting highly essential to driving more revenue.

Another factor to consider is the responsive web design. It implies that a web application should adapt to devices of several screen sizes and work as intended. Also, it should load quickly and have a smooth transition between pages.

A study conducted by Google stated that 53% of mobile users leave a website if it does not load within 3 seconds.

Developing such quickly-loading and responsive web apps is a challenging task. However, technological advancements have witnessed the inception of several web development frameworks. Among all frameworks, many web development companies and developers choose AngularJS. It serves as an ideal structure to stand out for delivering versatile arrangements following the necessities of individuals.

AngularJS is an open-source framework based on the foundation of HTML, JavaScript, and CSS. It is primarily used to create dynamic websites. It aids developers by making the whole web development process easy yet efficient. Further, it outspreads the HTML jargon by executing the highlights during the run-time. This results in more code comprehension and makes the development procedure effortless.

In this article, let us explore why companies or developers use AngularJS for responsive web application development. Before that, let us have a brief introduction to the framework.

What is AngularJS?

AngularJS is a free and open-source JavaScript-based web development framework. It is a structural framework for developing dynamic web apps. It is an older version of the Angular framework, a free and open-source TypeScript-based web development framework.

Earlier, Google was responsible for maintaining AngularJS. But now, the framework is discontinued, i.e., Google and its creators now no longer maintain it. As a result, it does not receive updates to fix any security, browser compatibility, and jQuery issues.  AngularJS’s stable version is 1.8.3, released on 7 April 2022.

AngularJS makes developing and testing dynamic web apps easy, providing a framework for client-side model–view–controller (MVC) and model–view–viewmodel (MVVM) architectures. In addition, it provides a framework for various components helpful in developing web apps and progressive web apps.

Furthermore, the framework was once used as the front-end component of the MEAN stack (MongoDB, Express.js, Angular, Node.js). However, it is now replaced by Angular.

The following are the design goals of the AngularJS framework:

• Separate the DOM manipulation from the application logic.
• Decouple the client side and server side of an application.
• Provide a clear structure throughout the application development, from UI design through testing and deploying.

Features of AngularJS

Here are some remarkable features of the framework:

• Two-way Data Binding

This implies any changes you make to data reflect immediately in the view, and vice-versa.

• MVC Architecture

MVC stands for Model, View, Controller. This architecture lets you divide your application into three layers – model, view, and controller.

• The model layer deals with the application data.
• The view layer displays that data.
• The controller connects the model and view layers.

This helps keep the presentation and the logic of applications separate.

• Dependency Injection

This feature lets you easily manage the dependencies between different components or modules, making testing and maintaining the source code more manageable.

• User Interface with HTML

You can create user interfaces in HTML with this framework. HTML stands for HyperText Markup Language, a declarative language with short tags, making it easy for everyone to learn and use.

• POJO Model

POJO stands for Plain Old JavaScript Objects. As this framework uses the POJO model, it eliminates the need to add getter and setter methods to bind it with data sources. Also, this model provides well-planned objects.

• Routing

Routing is switching from one view to another. Well, in a single-page application, everything is available on a single page. Generally, developers create single-page applications so that whenever users click on a menu or sub-menu, the page's content changes, not the URL. AngularJS makes it easy to generate multiple views of the same page.

• Not Browser Specific

Applications you develop using this framework are compatible with all major browsers except Internet Explorer 8.0. They support Class A browsers like Google Chrome, Safari, etc.

• Services

Services help you perform common tasks like logging, authentication, HTTP requests, and other simple web development tasks. This significantly saves time, eliminating the need to write code for these services from scratch.

Top 9 Advantages of AngularJS for Responsive Web Application Development

The framework outspreads the HTML vocabulary by executing the features during the run-time, thus resulting in increased code comprehensibility and faster development. Adding to it, here are a few more reasons why you must consider AngularJS for Responsive Web Development.

1. Optimized Security of Responsive Web Applications

The best-in-class security standards allow you to secure your AngularJS application. Additionally, you need to guarantee that all sessions on the server are secure and prepared for irregular calling patterns and injection attacks.

If your business needs to release the Angular front-end to a more prominent populace, there are numerous measures you can take to prevent cross-site scripting assaults. The $http module offers CSRF security. However, you should do server work to help with functionality.

You will find that Angular backings are exacting articulation assessments and enable you to use severe logic to get away. This should decrease your concerns about customer-side security. AngularJS is fantastically adaptable, so you will likewise have the option to actualise outsider security libraries like OAuth.

2. Ease of Creating Web Applications

This is the most important thing that compels developers to choose the framework. It helps them create web applications easily with no hassle. It accompanies ng-mode and ng-class, a portion of the regular tasks in JQuery. Additionally, the two-way data saving and binding tasks require just a few lines of code while developing applications using AngularJS.

3. Great Community Support

Since the framework is an offspring of Google, it comes with tremendous credibility, which has attracted a lot of developers to opt for it. There is a massive community of highly-skilled AngularJS developers who are talented enough to upgrade this open-source framework. They have meetings and conferences while welcoming IT organisations from around the world to furnish them with knowledge regarding progressions and new advancements in innovation.

4. Offers Secure Access Management

One worry that numerous endeavours have about upgrading an application for using AngularJS is whether it can use existing security strategies to keep up the level-of-access restrictions as ordered by departmental rules.

Luckily, because of the framework’s adaptability and flexibility, there are numerous choices that you can opt for to incorporate the current domain systems into the security stream and login of the application.

Since AngularJS is just a front-end inclusion, you can't benefit from this usefulness without supplemental libraries. Luckily, numerous supplemental libraries like Idapjs will enable you to actualise single sign-on using the association among libraries and AngularJS. You can use these external libraries by fusing some code and doing a security audit to distinguish any presented vulnerabilities.

5. Easy Leveraging of Data

The best part of AngularJS is that it has no limitations with data management systems. All AngularJS applications use RESTful APIs, enabling clients to access the basic database. You can use an Angular application to supplant existing frontend code using internal APIs. This licenses you to re-use server-side security effectively and rapidly.

Additionally, if the application you need to supplant worked with a web application framework like Rails or Django, the migration will be as simple and quick as a front-end swap. This will make improving your site's performance effortless with the order-based usage style of Angular.

6. Boosts Testability for Web Applications

Gradually, you should change your web application to support execution and address any issues. If your web application is hard to test, you will likely be unable to distinguish the problems or areas where there is an opportunity to improve.

A significant advantage of AngularJS is that it simplifies the testability of the web application. Dependency Injection (DI) is the center of this framework, which clarifies the areas that require testing. The framework has sufficient documentation regarding testing; therefore, it is very easy and effortless to test web applications.

7. Enables Efficient Parallel Development

The biggest issue the development industry faces while working simultaneously on a single project is stepping on each other’s toes.
