Advantages & Disadvantages of Choosing AngularJS Web Development

Angular JS is an open source framework for building web applications. Tech giant Google maintains it. Coders face many issues while developing and testing any code. It resorts many of the challenges which the coders may face.

AngularJS mixes HTML codes and app modules to form a framework. Its earlier base was Model View Controller (MVC) Architecture. It was mainly in use for planning rich web applications. But, situation has been on a change since the introduction of the Angular JS 2.

The new and superior features of this technology are a boon for the Angular JS Development Companies. The advanced technology can now naturally be in sync with models and view. This makes AngularJS web development a very simple process.

In short, some of the stand out features of AngularJS are:

– Two-way data binding

– MVC structure

– Directives

– Templates

– Dependency injections

– Testing

Apart from these basic advantages, these are the few reasons which make Angular JS the first choice for web development.

Let us look into these advantages in detail:

Most widely used Framework

AngularJS is one of the most widely used frameworks for creating websites. Also, for the mainstream development, Angular JS is in use. Moreover, it has a fine support of a global community of keen and talented developers.

Declarative Code Style

The most hectic job in coding is writing codes for every little function. You need to write multiple codes for adding a single function. With the declarative coding paradigm, AngularJS ensures that the coders have to write fewer codes. The coding reduces for executing the same goals. In simpler terms, you do not need to write all the steps involved in any action. You just have to write the final steps!

Wide Recognition

AngularJS web development is a globally known framework. It is in use for developing high quality apps. In addition, it is also known for developing hybrid apps. Many development frameworks and stacks across the world are using AngularJS for this purpose. It has a wider global acceptance and is trending currently as a technology for developing web apps.

Data Binding

For enhancing the testing ability, Angular JS is in use. Testing enhancement is because the decoupling of data can have the view of DOM element or HTML. The developer can effortlessly identify the logic that controls this data. Moreover, the data separation is also very simple. Hence, the division of UI element and its representation makes viewing a pleasing experience than other frameworks.

We have seen the positives of Angular JS development. Now, let us see why few web development companies remain distant from using AngularJS.

The Disadvantages of AngularJS

Performance Glitches

As the apps developed under the AngularJS framework are dynamic. These dynamic apps lack in performance. Sometimes complex single page apps can have some lags and show glitches while performing.

Need Professionals

An entrepreneur may look at Angular JS as the best suitable framework for web app development. But, you get to know that your classical web development knowledge would create confusion when you use AngularJS. Features like dependency injection and firm can be challenging for you. Either you will have to invest more time in learning or you may have to look for professional help.

JavaScript Mandatory

Nothing in the world is absolute. Is it universal that all the computers and laptops would have a JavaScript support enabled? When you own a business, you want to reach maximum number of people. When JavaScript support is missing, your website or app would not be able to reach these people. Your web app would become less useful. Instead, if you use HTML as the base for web development, this problem eliminates.

AngularJS For Web Development

Nowadays, consumers access websites and web applications on a wide variety of devices, operating systems, and browsers. Hence, developers have to focus extensively on website’s user interface (UI) to make it easy to access, use, and navigate. As a robust client-side programming language, JavaScript helps developers to build rich web user interfaces (UIs). The developers can further accelerate web UI designing by using a number of front-end JavaScript frameworks. AngularJS is a widely used front-end JavaScript framework developed and maintained by Google.

Like other open source JavaScript frameworks, AngularJS also helps developers to curtail overall web application development cost. But it accelerates custom web application development by enabling programmers to express various components of a web application by extending HTML syntax. Also, AngularJS updates the web application’s UI each time the backend changes by supporting two-way data binding. The developers can further extend AngularJS by integrating it with various JavaScript libraries. There are also a number of reasons why many web developers prefer AngularJS to other front-end JavaScript frameworks.

Why Most Web Developers Prefer AngularJS to Other Front-end JavaScript Frameworks?

Extends HTML Syntax

In addition to being written in JavaScript, AngularJS is also distributed as a JavaScript file. It can be embedded into a web page directly through the script tag. Also, it allows developers to express various components of a web application by extending HTML with three ng-directives – ng-app, ng-model and ng-bind. The web developers can even use AngularJS expressions to bind AngularJS data to HTML without writing additional code.

Implements MVC Pattern Differently

Model-view-controllers enable developers to simplify development of large web applications by keeping their user interface and business logic separated. But AngularJS implements MVC pattern in a distinct way. The AngularJS team calls the distinct implementation of MVC pattern as model-view-whatever. The model-view-whatever architecture makes it easier for programmers to improve the performance and maintainability of complex web applications.

Supports Two Way Data Binding

In addition to implementing MVC architecture differently, AngularJS also supports two-way data binding. The feature helps developers to synchronize the data between model and view components without putting extra effort. AngularJS automatically updates the web application’s frontend each time its backend changes. As AngularJS synchronizes the model and view automatically, the developers are not required to implement DOM manipulation.

Improves Server Communication

AngularJS reduces web server load significantly by supporting caching. At the same time, the built-in services provided by AngularJS help developers to improve client-server communication. The services further make it easier for web developers to work with various backend systems and solutions. Also, the developers can take advantage of the built-in services to make the data return asynchronously without writing complex code.

Implements Client-Side Form Validation

The web developers can create a variety of forms by combining HTML, CSS and AngularJS. AngularJS further helps developers to implement client-side form validation. It monitors the state of the form as well as individual text fields. It even notifies users about the current state of the form or input fields. The developers can easily validate the form input using standard HTML5 attributes. AngularJS even allow them to write and use custom validation functions.

Keeps the Code Maintainable and Testable

AngularJS helps developers to write readable and maintainable code by extending HTML syntax. In addition to extending existing HTML tags, the developers can use directive to create custom HTML syntax. At the same time, the framework keeps the code testable by allowing programmers to use plan JavaScript objects. The models in AngularJS are also designed as plain JavaScript objects. Hence, the developers can use the framework to write clean, readable, maintainable, and testable code.

Provides a Built-in Dependency Injection Subsystem

Often frontend web developers use dependency injection tools to inject dependency to an object in the most appropriate way and make the objects exchange dependencies seamlessly. AngularJS simplifies dependency injection by providing a built-in dependency injection subsystem. The dependency injection subsystem makes it easier for developers to replace individual components off the web application, along with performing testing.

A Component of MEAN Stack

Many web developers prefer using AngularJS as a key component of MEAN stack along with MangoDB NoSQL database, Express.js and Node.js. As full-stack JavaScript, MEAN enables programmers to write both client-side and server-side code in JavaScript. With more and more enterprises opting for isomorphic applications, AngularJS is being used widely by developers as a component of MEAN stack.

Several AngularJS-based Frameworks

In addition to integrating AngularJS with a number of widely used JavaScript libraries, the web developers also have option to avail several AngularJS-based frameworks – Suave, PrimeNG, QuantumUI, Semantic UI and UI Bootstrap. The UI components provided by these AngularJS-based frameworks make it easier for web developers to build custom web-based user interfaces. Also, these frameworks help developers to create responsive and cross-browser web user interfaces.

Keeps Evolving

As mentioned earlier, AngularJS is maintained by Google along with a community of developers. Hence, it keeps evolving consistently to simplify and speed up web application development. In November, AngularJS 5 was released with a number of new features. The latest version of the JavaScript framework simplifies development of progressive web applications, removes unnecessary code from the application through a build optimizer, and provides a new HttpClient.

On the whole, the features provided by AngularJS help web application developers to build custom web UIs in a short amount of time. But the web developers must remember that AngularJS, like other JavaScript frameworks, has its own pros and cons. They have to integrate AngularJS with other JavaScript libraries and frameworks to accelerate custom web application development. They can still use the latest version of AngularJS to avail a set of new and improved features.
