Angular 2: a Big Change

Posted By Anupam Singh on 29th July 2016
what makes a mobile app popular

Angular JS provides a framework to decouple our UI (DOM) from the client side business logic (the JavaScript understood by the browser). It also comes with a client side MV* framework in order for us to reuse source code across platforms (web and mobile).

Angular JS, was initiated as an internal project by Google in 2010, this became quite popular within a couple of years and the Software industry has adapted Angular JS as a core front end development framework for their next generation application.

Before Angular JS, there were a few frameworks, such as: YUI from Yahoo, ExtJS from Sencha and Jquery (Jquery, being the most popular), which were used, and are still being used, to develop client side applications. All of these frameworks come with handy functions which allow us to work with HTML elements (DOM), leading to monolithic dependency between our JavaScript code (business rules) and the UI.

Why do we need a client side framework?

A framework is important for any application development. Generally, many developers work together to develop a large scale application, each have their own way of writing code. There are coding guidelines and conventions that are usually followed, however, the framework is allowed to control the overall flow of code and process.

Since the break-through changes in angular 2, developers who have released applications using Angular 1.x are working to upgrade from Angular 1.x to Angular 2. The Angular 2 community has released UpgradeAdapter to upgrade Angular 1.x to Angular 2 but it’s quite difficult to upgrade without re-writing your existing source code.

Angular 2 has written from scratch in order to make it a modern framework which uses ES6/7 standard and to ensure it is compatible with ES5. The reason to choose Angualr 2 is because it uses a component based concept which focusses on component re-use to produce less bulky and more maintainable code.

Developing scalable web application using Angular 2

Angular 2 uses Component Based Architecture instead of MV*. A component is an independent, reusable and pluggable part of an application. A typical component overview is as follows. A component can be used independently or can be extended for use along with other components. An advantage of component based architecture is, it reduces development time as we can reuse existing components. Moreover, in order to develop scalable applications, we can enhance existing components for better reuse instead of developing entirely new functions.

Why should you choose Angular 2 to develop your next generation web applications?

Nowadays, it is imperative to choose cutting edge technology to develop your bespoke application development. Everyone wants to target larger audiences, this is only possible when you choose the technology that targets users across different platforms: mobile (iOS Application Development, Android Application Development, Hybrid Application Development), tablet and desktop clients.

Since we are adapting Service Oriented Architecture to keep the business layer isolated and support all the smart devices and as well as different client services (eg. authenticating application users from Google and Facebook,) It is worth choosing a front end framework which provides a reusable, testable and upgradable environment to deliver the best software solution to your clients.

The four pillars of Angular 2:

1. DRY (Don’t repeat yourself)

2. Declarative

3. Data Binding

4. DI (Dependency Injection for loose coupling)

Conclusion

Once you start working with Angular 2, you will find it is a simple framework to work with and an invaluable tool for modern front end development.
