[Angular Material: DatePicker] Set Custom Date in (DD-MM-YYYY) format

As working with Angular Material 8 DatePicker Component, i was not able to set the Date in a specific format. After spending 2 hours of researching, i achieved the Goal by following multiple articles. Later thought why don’t i make it easy for others, who might get into the same situation.

So here i am, Back with another problem solving magical thing, Here i was using Template-Driven Approach to build forms.

The HTML CODE

<mat-form-field>
<input matInput placeholder=”Select Date” [matDatepicker]=”datepickerRef” name=”datepicker” ngModel #dateCtrl=”ngModel” required readonly/>
<mat-datepicker-toggle [for]=”datepickerRef” matSuffix></mat-datepicker-toggle>
<mat-datepicker #datepickerRef></mat-datepicker>
<mat-error *ngIf=”dateCtrl.errors?.required && deptCtrl.touched”>Choose a Date</mat-error>
</mat-form-field>

The HELPER Function

This is the functionthat will translate the Date to DD-MM-YYYY format as the example, however you can customize it accordingly. I created a single file named “format-datepicker.ts” and written following code..

import { NativeDateAdapter } from ‘@angular/material’;
import { MatDateFormats } from ‘@angular/material/core’;
export class AppDateAdapter extends NativeDateAdapter {
  format(date: Date, displayFormat: Object): string {
    if (displayFormat === ‘input’) {
      let day: string = date.getDate().toString();
      day = +day < 10 ? ‘0’ + day : day;
      let month: string = (date.getMonth() + 1).toString();
      month = +month < 10 ? ‘0’ + month : month;
      let year = date.getFullYear();
      return `${day}-${month}-${year}`;
    }
    return date.toDateString();
  }
}
export const APP_DATE_FORMATS: MatDateFormats = {
  parse: {
    dateInput: { month: ‘short’, year: ‘numeric’, day: ‘numeric’ },
  },
  display: {
    dateInput: ‘input’,
    monthYearLabel: { year: ‘numeric’, month: ‘numeric’ },
    dateA11yLabel: { year: ‘numeric’, month: ‘long’, day: ‘numeric’
    },
    monthYearA11yLabel: { year: ‘numeric’, month: ‘long’ },
  }
};

Provide this implementation inside the providers tag of Component Decorator by overriding the default,

import {DateAdapter, MAT_DATE_FORMATS} from '@angular/material/core';
import { AppDateAdapter, APP_DATE_FORMATS } from 'src/app/shared/format-datepicker';
@Component({
  selector: ‘app-create-employee’,
  templateUrl: ‘./create-employee.component.html’,
  styleUrls: [‘./create-employee.component.css’],
  providers: [
    {provide: DateAdapter, useClass: AppDateAdapter},
    {provide: MAT_DATE_FORMATS, useValue: APP_DATE_FORMATS}
  ]
})

And Boom, You will see the result!

Leave a few claps, if this article helped you in any way :)
