Format Date Using Pipe in Angular.

First you need to import DatePipe module file and add it to the providers array in your app.module.ts file.

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

import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { DatePipe } from '@angular/common';


@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    AppRoutingModule
    BrowserAnimationsModule
  ],
  providers: [DatePipe],
  bootstrap: [AppComponent]
})
export class AppModule { }

Create an instance of DatePipe in your component file.

public currentDate: any;

constructor(private datePipe : DatePipe){}

ngOnInit(){
  this.currentDate = new Date();
}
