What is Pipe of Date Angular?

Pipe of Date Angular is a feature in Angular that allows us to format date values in a convenient and flexible way. It is a built-in pipe that can be used to transform a date object into a string of desired format.

Syntax of Pipe of Date Angular

  {{ dateValue | date: 'format' }}

• dateValue : The input value that we want to format.
• format : The desired date format string.

Below is an example of how to use Pipe of Date Angular in HTML:

  <p> Today's date is {{ currentDate | date:'fullDate' }} </p>

Here, the value of the currentDate variable will be formatted as per the 'fullDate' format string and displayed in the HTML.

Available Date Formats in Pipe of Date Angular

• 'short': 'M/d/yy, h:mm a'
• 'medium': 'MMM d, y, h:mm:ss a'
• 'long': 'MMMM d, y, h:mm:ss a z'
• 'full': 'EEEE, MMMM d, y, h:mm:ss a zzzz'
• 'shortDate': 'M/d/yy'
• 'mediumDate': 'MMM d, y'
• 'longDate': 'MMMM d, y'
• 'fullDate': 'EEEE, MMMM d, y'
• 'shortTime': 'h:mm a'
• 'mediumTime': 'h:mm:ss a'
• 'longTime': 'h:mm:ss a z'
• 'fullTime': 'h:mm:ss a zzzz'

We can use any of the above formats or create our custom format string using predefined format options. Below is an example of how to create a custom format string:

  <p> Today's date is {{ currentDate | date:'MMM dd, yyyy h:mm a' }} </p>

Multiple Ways to Use Pipe of Date Angular

Apart from using Pipe of Date Angular in HTML, we can also use it in TypeScript code. Below is an example of how to use it in TypeScript code:

  import { Pipe, PipeTransform } from '@angular/core';
  import { DatePipe } from '@angular/common';

  @Pipe({ name: 'customDate' })
  export class CustomDatePipe implements PipeTransform {
    transform(value: any, format: string): any {
      const datePipe = new DatePipe('en-US');
      return datePipe.transform(value, format);
    }
  }

Here, we have created a custom pipe named 'customDate' that takes two arguments: 'value' and 'format'. We have used the DatePipe provided by Angular to transform the input date value into a string of desired format.

We can use this custom pipe in HTML like this:

  <p> Today's date is {{ currentDate | customDate:'MMM dd, yyyy h:mm a' }} </p>

There are many other ways to use and customize Pipe of Date Angular. It is a powerful feature that can make our date formatting tasks much easier and efficient.
