Creating Angular Application & Module Installation:

Step 1: Create an Angular application using the following command.
```
ng new appname
```
Step 2: After creating your project folder i.e. appname, move to it using the following command.
```
cd appname
```

Step 3: Install PrimeNG in your given directory.

npm install primeng --save
npm install primeicons --save

Project Structure: It will look like the following.

Example 1: This is the basic example that shows how to use the InputMask component

app.component.html

<h2>GeeksforGeeks</h2>
<h5>PrimeNG InputMask component</h5>
<div class="p-fluid">
  <div class="p-lg-4">
    <p-inputMask mask="999 999 9999" placeholder="999 999 9999"></p-inputMask>
  </div>
</div>

app.module.ts

import { NgModule } from "@angular/core";
import { BrowserModule } from "@angular/platform-browser";
import { FormsModule } from "@angular/forms";
import { BrowserAnimationsModule } from
    "@angular/platform-browser/animations";

import { AppComponent } from "./app.component";

import { InputMaskModule } from "primeng/inputmask";

@NgModule({
  imports: [
    BrowserModule,
    BrowserAnimationsModule,
    InputMaskModule,
    FormsModule,
  ],
  declarations: [AppComponent],
  bootstrap: [AppComponent],
})
export class AppModule {}

Example 2: In this example, we will know how to use disabled property in the InputMask component

<h2>GeeksforGeeks</h2>
<h5>PrimeNG InputMask component</h5>

      placeholder="999 999 9999"
    ></p-inputMask>
  </div>
</div>

app.module.ts

import { NgModule } from "@angular/core";
import { BrowserModule } from "@angular/platform-browser";
import { FormsModule } from "@angular/forms";
import { BrowserAnimationsModule } from 
    "@angular/platform-browser/animations";

import { AppComponent } from "./app.component";

import { InputMaskModule } from "primeng/inputmask";

@NgModule({
  imports: [
    BrowserModule,
    BrowserAnimationsModule,
    InputMaskModule,
    FormsModule,
  ],
  declarations: [AppComponent],
  bootstrap: [AppComponent],
})
export class AppModule {}
