Should pipes implement PipeTransform interface

Question

Can you help me with a code example? Should pipes implement the PipeTransform interface?

Answer 1

Yes, pipes in Angular must implement the PipeTransform interface. This interface requires the pipe class to define a transform method, which is responsible for performing the data transformation.

Key Points:

PipeTransform Interface:

Provides a standard structure for pipes.

Ensures the transform method is implemented.

transform Method:

Takes the input value and optional parameters.

Returns the transformed value.

Example:

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

@Pipe({ name: 'customPipe' })

export class CustomPipe implements PipeTransform {

  transform(value: any, ...args: any[]): any {

    // Transformation logic here

    return transformedValue;

  }

}
