Module Pattern

The Module Pattern in Angular refers to organizing your Angular application into modules.

Modules in Angular are containers for a group of related components, directives, services, and pipes.

They help in organizing the application into cohesive blocks of functionality.

Here's a simple example of how you can define a module in Angular:

// app.module.ts

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';

import { AppComponent } from './app.component';
import { HeaderComponent } from './header.component';
import { FooterComponent } from './footer.component';

@NgModule({
  declarations: [
    AppComponent,
    HeaderComponent,
    FooterComponent
  ],
  imports: [
    BrowserModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

In this example:

• We import the NgModule decorator from @angular/core, and other necessary modules such as BrowserModule.

• We declare components (AppComponent, HeaderComponent, FooterComponent) within the declarations array. These components belong to this module.

• We import required modules like BrowserModule in the imports array.

• The providers array can be used to provide services at the module level.

• bootstrap array specifies the root component of the application.

This is a basic example of the Module Pattern in Angular.

You can have multiple modules in your application, and each module can have its own components, directives, services, and pipes.

Modules help in organizing code, promoting reusability, and keeping the application maintainable.
