Angular as a framework
Why Use Angular
A are lots of paybacks attached to using angular for application development. Let look into some good reasons why you should use Angular for your application projects.
The Angular CLI is a wonderful tool that has an ever-growing list of capabilities. Over time, it will likely do many more things than ever expected, and has some dynamic capabilities as well.
The Angular CLI (often just referred to as the CLI) is the official toolchain for building Angular applications that provide these features and more. You could roll your own build tooling, but that’s suggested only if the CLI doesn’t meet your needs. You can install the CLI using npm. Make sure you have the recent version of NodeJS installed for it to run properly:
Writing codes can sometimes be painstaking and will definitely consume a good amount of time. At some point, you definitely want to reuse the codes you have written but you do not have the luxury of time to write them over again. With angular, you will be able to write lesser codes and reuse them without worrying about writing your own MVC structure.
- Data Binding and Filters
The reason why you need not worry about your own MVC is that Angular done that for you already by using HTML to define the view. You don’t have to manually put data into the view, data binding does all that for you. Also, without changing the controllers, you can manipulate data on the view level. Filters are exceptionally great in making our data reusable and scalable at the same time.
Two-way binding has a change detection system that displays any change of value modified by the event handler and enables changes of the underlying data model to reflect immediately on the user interface. Unlike other frameworks using this type of data binding via complex series of event listeners and handlers, this can be done automatically with angular and doesn’t need intervention by the programmer. With this feature, lots of logic from the front-end code will be removed making the application lighter.
- Service Providers
If you need an outward API to expose different methods, service providers are there for you. One good thing about services is that it does not get involved with the MVC of your project. Services are standalone objects designed to be separated from your applications. Services are used to share data and behavior within an application.
The Angular directives are used in creating customized HTML tags and attributes used to sustain the power of HTML. The @Directive decorator has to be applied to connected metadata of the class.
- Template Directives
The directives can create a reusable HTML template. Directive writers such as “ng-repeat” and “ng-if”, could completely control the instantiating of this template and its insertion into the DOM.
This is data of data which can be used to add additional data to Angular 2 or Angular 4 class. It can help us decorate class so that it gets configured to achieve the expected behavior of the class. Examples are “annotations” and “parameters”.
