I have created a custom pipe in Angular, but when I try to use it, I keep receiving the error message: "No pipe found with name 'RefPipe'". I have searched for solutions online and they all suggest importing the pipe. However, I have tried importing it in different folders without success. Initially, I imported the pipe in app.module.ts so that it could be accessed globally, but that didn't work either. Then, I attempted to import it directly into the ts file of the component where I am trying to use the pipe, but I still encounter errors. Any assistance on this matter would be greatly appreciated.
<p>Book ID: {{bookParent.id_book | RefPipe}}</p>
import { CommonModule } from '@angular/common';
import { Component, Input, Output, EventEmitter } from '@angular/core';
import { Book } from '../module/book';
import { NgClass, UpperCasePipe } from '@angular/common';
@Component({
selector: 'app-card',
standalone: true,
imports: [
NgClass,
UpperCasePipe,
CommonModule
],
templateUrl: './card.component.html',
styleUrl: './card.component.css'
})
import { RefPipe } from './pipes/ref.pipe';
@NgModule({
declarations: [
AppComponent,
HeaderComponent,
FooterComponent,
HomeComponent,
FormRegisterComponent,
ProfileComponent,
RefPipe,
CommonModule
],
imports: [
BrowserModule,
AppRoutingModule,
FormsModule,
AddBookComponent,
UpdateBookComponent,
],
providers: [
provideClientHydration(),
BooksService,
RefPipe
],
bootstrap: [AppComponent]
})
export class AppModule { }
The code for the pipe is as follows:
import { Pipe, PipeTransform } from '@angular/core';
@Pipe({
name: 'ref',
standalone: true
})
export class RefPipe implements PipeTransform {
transform(value: string, count:number):string {
let result = "";
for(let i = 0; i<count;i++){
result += "-ref" + value
}
return result;
}
}
