Module

Modules are like containers for components, directives, services, etc. They help to organize an Angular application which makes it easier to manage or scale application. Modules also support lazy loading means it is used to improve application performance by loading specific parts of the application only when they are required. The root module also known as App Module provides a starting point for the application.

Javascript




// app.module.ts
import { NgModule } from '@angular/core';
import { BrowserModule } 
    from '@angular/platform-browser';
import { AppComponent } from './app.component';
  
@NgModule({
    declarations: [
        AppComponent
    ],
    imports: [
        BrowserModule
    ],
    providers: [],
    bootstrap: [AppComponent]
})
export class AppModule { }


What are the main building blocks of an Angular Application?

Angular is a widely used open-source front-end framework used to build dynamic web applications. It consists of several key building blocks that work together to create scalable, and maintainable applications. In this article, we will explore all the main building blocks of an Angular application and we will explore how they contribute to framework architecture.

Angular Application Architecture

An Angular application follows the Model-View-Controller (MVC) and Model-View-ViewModel (MVVM) principle design patterns. The Model View Controller (MVC) design pattern specifies that an application consists of a data model, presentation information, and control information. In the Model-View-ViewModel (MVVM) design pattern, the Model component resembles the same concepts as in the traditional Model-View-Controller (MVC) pattern, along with facilitating the extended and adapted to better support the requirements for data binding and the ViewModel....

Templates

Components are the fundamental block for the Angular application interface. They combine the presentation layer (template) and component class. They also enable the creation of custom HTML elements and help in transforming the user interface into a collection of self-contained and easily maintainable units. Each component is recognized by means of a completely unique selector, which acts as a custom HTML detail, enabling you to embed it within other components or templates. Components are the visible entities in which users interact with it without any delay, making it a crucial part of the user experience....

Data Binding

Templates define the structure of components using Angular templating syntax. They display the data and provide the structure for the user interface. Angular template syntax is also used to combine HTML with Angular-precise directives and bindings. Directives work as markers in the template that teach Angular how they can transform the DOM earlier than rendering it....

Metadata refers to the facts that are associated with various elements in an Angular application like components, modules, directives, and so forth. Metadata is furnished using decorators, which can be special capabilities that attach extra statistics to the elements. This metadata facilitates Angular to apprehend the method and use these factors. They also are used to configure and define numerous factors of application elements such as their behavior, look, and relationships with other elements....
