Angular is the framework that provides a clear understanding of how the application should be structured and offers real DOM to flow bi-directional data.
It is the full-fledged model-view-controller framework that includes Component, Template, Directive, Service, and Module. This framework is used to build client applications through languages like HTML and Javascript.
Before you start to understand the Angular Architecture, let’s read some glimpse of it:
“The HTML templates and different modules are used to define the Angular application. Further, the component classes are used to manage the written templates and arrange the service boxes, boxing components and service modules. After that, the application is launched by the root module of bootstrapping. This way, Angular presents your app content in a browser to interact with maximum users.”
Let’s move on to eight building blocks of the Angular Application:
How Angular Application Works?
1. Module
The very first block called as Module. An Angular App has a root module which offers the bootstrap mechanism to define the application. The most important properties of the Module block involve exports, imports, and bootstrap. However, the whole mechanism involves many functional modules to manage the development of the application and maintain its re-usability.
2. Service
This is basically created when reusable data services between two components. The class is mentioned @injectable(). Further, it is created for the data or logic to acknowledge across sections.
3. Dependency Injection
This enables to keep the element classes simple and easy. It doesn't pull information from the server, check input validation, or log to the terminal directly. However, it delegated these responsibilities to the companies.
4. Templates
The template of Angular modifies with the Angular markup and HTML elements. Users can alternate values derived from your distributed applications into HTML using property bindings.
5. Metadata
Angular uses metadata to determine the function of the class. It's used to customise a class's intended behaviour. The metadata is also applied to determine how to handle a class.
6. Components
The second block is components which means the collection of JavaScript modules. However, the application defines each component with specific data. Basically, it defines the subjective part of the application which is the User Interface (UI).
7. Data binding
This block plays an important role in binding relationship between a template and components. Basically, it involves the communication function in between the parent and child. With this block, Angular allows all the components and the DOM to communicate for the easy flow of in and out data. Different types of data binding supports the process, here are some:
1. Interpolation allows screen to view the component. This symbol {{title}} used to display the value of the component on the screen.
2. The second is property binding which is used to update DOM components. The symbol [class] is update the style class of the element.
3. Event binding is the another one. Specifically used to handle the event by coding.
8. Directive
Well, we know that Angular is dynamic. Therefore, this block helps in renders and transforms the DOM component. Also, there are two types of directive:
1. The first one is structural directive that is used to change the structure of DOM template.
2. The second one is Attribute Directive which is used to update the components of HTML.
Wrapping up
This article has covered the basic understanding of Angular Architecture. However, it is critical to have a better understanding of Angular Architecture to get fit into the role of Angular developer.
Besides knowledge, this kind of topic is critically asked by the recruiter in meanwhile hiring developer. Hence, if you need to build your career on the same, then exhibiting great Angular Developer skills, roles and responsibilities how Angular developer framework works are important.
Hope! You enjoy reading this one.
