It is hard to imagine web development without AngularJS. It is an open-source framework designed on Java. AngularJS is extensively used and more preferred over other frameworks like Ember.js, Meteor, Backbone.js, etc. as it provides simple integration and ease of optimization. AngularJS is controlled by Google to simplify the development and testing process among the developers all around the world. It has created a ripple in mobile and web development companies and series of versions are introduced since it's release.
The mobile and web applications have changed the work habits and browsing methods of people. In meantime, application development also went through the number of fresh changes. As there are numerous cutting-edge tools and frameworks available, AngularJS stands out among them. What makes it so special and unique? Does it user-centric nature of AngularJS? Or it's incredible features and functionality?
Basically, MVC (Model-View-Controller) architecture is followed strictly in this framework to build rich applications. It follows the basic HTML and provides developers capabilities to make the application dynamic and responsive. Also, Document Object Model (DOM) technique aims mainly on improving performance and testability. Well, this is just an overview of AngularJS, let's dive into why is AngularJS perfect for the web and mobile application development? What features and functionality does it provide?
AngularJS is Best for Single Page Application
Why are single page applications in huge demand? Because they offer sophisticated user experience. SPA also known as Single Page Application, fits on a single web page with dynamic actions requires no page refreshing. This kind application provides active buttons and hyperlinks on the website to improve the user engagement with web pages. If AngularJS is used to develop SPA, there will be full independence to write the code. It requires no additional queries to the server to download the pages. Performance can improve in many ways as each of CSS, HTML, and JS file loads Single time. This means once the web page is loaded, there is no need to reach the server every time.
Two-way Data Binding for Auto-Synchronization
What is two-way data-binding? Well, any modification in user interface instantly reflects on objects of application and vice-versa. AngularJS follows MVC framework so auto-synchronization between the model and view components is necessary. However, in a conventional template, systems bind data only in one direction as data have to be merged with model components into a view. Therefore whenever there are changes, developers need to write code that continuously synchronize the view with model and inversely. Two-way data binding in AngularJS updates the necessary patterns as framework encounters module changes, browser event, and user actions on the web page. It also eliminates the storing and direct manipulation of links to DOM elements.
Data models in Angular are POJO and don’t need additional getter and setter functions. Developers can add and modify properties directly on it and loop over objects and arrays on their wish. With POJO code look more intuitive and cleaner. Old data models act as a watch person and are in control for data persistence and server synchronization. But, Angular data models are plain objects and behave like a cork board. But what is cork board? It is a temporary registry to store and retrieve data. The cork board in AngularJS works closely with controller and view components. All the properties related with POJO are automatically bound to view.
Custom Directives to Add More Functionality
It is one of the exceptional advantages of AngularJS that it allows developers to deal with custom HTML directives. Sometimes, in built directives can be tricky and unhelpful. Custom directives add more functionality to HTML code. For example, <calendar> </calendar>, <grid> </grid>, <lightbox> </lightbox>
It indicates the additional and necessary information which is added into the code. It also focuses on developing logics and allows developers to work more productively. The important thing to remember, developers never need to manipulate the DOM to simulate custom directives. Applications just have to understand the element attributes to the functionality. Directives are standalone reusable elements separate from the app.
