Easier to work on
Binding & Expressions
Two-way binding is a core AngularJS feature, among its most useful. It saves you valuable time, that would otherwise go into writing voluminous code. Lesser code to write allows you to focus on the application. Before attempting ways to bind data, setting up a source model to read data is a necessary step. Data binding automatically synchronizes data between model and view components. Angular templates work differently – the template is compiled on the browser, the compilation providing a live view. Changes made to the view are immediately reflected. The model breaks down the entire sequence to simple bits for the programmer.
One of the most powerful AngularJS features, directives help in extending HTML to serve web application needs. They allow specification with regards to page structure. There are several directives that aid in building the application. One of them is ‘ngRepeat’, this directive helps to create a new element set for every element in the collection. Whether an element is to be displayed or not, can be decided with the directive ‘ngShow’. There are other directives to imply, from ‘ngSwitch’, ‘ngModel’, ‘ngMyAwesomeDirective’ to ‘ngShow’, each performing a complex function.
The DI Factor
The dependency injection (DI) system is an intrinsic part of the framework. It helps the programmer in comprehending, making and testing the application. DI presents you with the dependencies, you don’t have to go searching for them. You name the dependency and DI will take over the search process. Moreover, you may define your own customized services and AngularJS will make them usable for DI. True unit testing is not dependent on any services or rendering and retaining the ability to create end-to-end tests, thanks to DIs.
AngularJS has the luxury of inbuilt routing. But if you still find limitations in the functionality, go for Angular UI-Router, mainly because of its dual features. You can avail the features of nested views and multiple views, thus add dynamism to the web application and its working. Matching specific URL content to a certain functionality; URL routes are so programmed that they display URL-focused content to the web application users.
The HTML Factor
That AngularJS uses the good old classic HTML language consequently makes it easier for both programmers and designers to work with it. Either party doesn’t have to depend on the other for interaction, the usual rules will apply to each party, thus making it a familiar process. For instance, creating the user interface and aligning various UI sections together will be easy, thanks to the HTML knowledge that application creators are equipped with.
Promises & Scope
The application model is referred to as Scope, there is a hierarchy to it that replicates the application’s DOM structure. From Scopes, we derive APIs to cause any model changes and in case of model mutations. Evaluation of expressions makes sense only when Scopes allows the context.
Clean & Effective
Modules & ‘The View’
Applications are classified in modules. Directives, filters, controllers and services, can all be part of a module. Keeping your web application in smaller, broken up segments makes it easier to be tested and troubleshooted. This matches with the AngularJS approach of creating easily-maintainable web applications. Dependency injection plays a key part in fusing together your application components. After parsing and compilation of the HTML to make rendered bindings and markup by AngularJS, the HTML is ‘the view’. This section provides solid ground to design your application.
Testing & Embedding
Testing your AngularJS applications is no mean task, thanks to the in-built testing set up in the framework that invites you to do so. The application programming interface (API) is inclusive of detailed tests that will display how any part of the framework will function.
Another prime advantage, AngularJS aligns with most applications, to embed an app of AngularJS with any other app is a smooth process. The framework’s equation with technology has been unhindered too, adding to its all-round utility.
