Angular 5 - currencyPipe

Update Angular 8

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

@Pipe({ name: 'CustomeCurrency' })
export class CustomCurrencyPipe implements PipeTransform {

    constructor(private currencyPipe: CurrencyPipe) { }
    transform(value: any, currencyCode?: string, display?: string | boolean, digitsInfo?: string, locale?: string): string {
        if (value != null)
            return this.currencyPipe.transform(value, currencyCode, display, digitsInfo, locale);
        return this.currencyPipe.transform(0, currencyCode, display, locale).split('0.00')[0];
    }
}

Try this simple custom currency pipe

{{ null | CustomeCurrency }}</p>

import { Pipe, PipeTransform } from '@angular/core';
import { CurrencyPipe } from '@angular/common';
@Pipe({ name: 'CustomeCurrency' })
export class CustomCurrencyPipe implements PipeTransform {

constructor(private currencyPipe: CurrencyPipe) { }

transform(value: any, currency: string, symbol: boolean = false): string {
     if (value != null)
        return this.currencyPipe.transform(value, currency, symbol);
    return this.currencyPipe.transform(0, currency, symbol).split('0.00')[0];
 }
}

If you're getting the error message The currency pipe has been changed in Angular v5. The symbolDisplay option (third parameter) is now a string instead of a boolean. The accepted values are "code", "symbol" or "symbol-narrow". then refer to the Angular documentation for help, use the code samples on this page to fix the issue: https://angular.io/api/common/CurrencyPipe
