The first and the most obvious concern that might prevent you from using the AngularJS framework could be the learning curve – that make you understand how to use the Angular JS framework – and best practices you need to follow when implementing your app. Secondly, since jQuery is used for a lot of projects, adopting some framework to do the task requires a lot of considerations and careful evaluation.
Two-Way Data Binding Reduces Boilerplate Code
But, thanks to AngularJS two-way data binding, the models can be bind – declaratively – to HTML elements. And so, when the model updates, the view also gets updated automatically. This helps in reducing the boilerplate code which otherwise increases when trying to keep the model and the view in synchronization.
Directives Helps Create Custom HTML Elements
With the help of AngularJS Directives, you get to embed additional functionality in your HTML. Just imagine, wouldn’t it be great if you could make use of HTML elements (such as and many others) without having to make changes to the DOM to stimulate them. This can be achieved with the help of AngularJS directives, as they in creating custom HTML elements.
For instance, you can create a simple component such as , so as to create your own custom date picker widget. Or in case you want to create folder uploader with extended features such as progress indicator, or else, you just need to create a component. In a nutshell, you can create a component to address your exact needs.
Reduces the Need to Write More Code
After going through all of the aforementioned points, you can possibly make out that the AngularJS framework help write less code. HTML is used to define the view, which results in making the view more concise. Besides, without having to use the getters or setters to make the data models simplified.
Furthermore, the separation of directives from the app code, allows another team of developers to work on the same codebase in parallel, which helps reduce the integration issues, and so on. This might look to you a summary of all the points, but considering the fact that you can write less code – make this key point worth checking out.
Allows Unit Testing
Following the traditional testing approach for web apps – will make you create individual test pages – wherein one page invokes a single component first and then interact with it to check out if it works or not. But, AngularJS provides a better unit testing approach over the traditional one. The Angular framework makes you ready to perform unit testing on components because of Dependency Injection (DI).
Since all the controllers count on dependency injection for passing the information, AngularJS’s unit tests takes over DI, and make it implement unit testing. To do so, the mock data is injected into the controller, which help measure the output and behavior. Moreover, the Angular framework comes with a mock HTTP provider, which will make you able to insert forged responses of a server into controllers.
Make Creating Single Page Applications a Breeze
Developing a single page app (SPA) is not an easy task. But, AngularJS framework makes it easy for you to build performant single page apps. In addition, the apps are responsive, and hence, adjusts and adapts to different screen sizes, providing an enhanced user experience compared to web apps. Furthermore, the apps created using AngularJS are rendered on the client-side, such type of applications helps in reducing the network traffic. This eventually helps in reducing the load on the server.
