String date in the format "dd-MM-yyyy" cannot be transformed into a date using the 'DatePipe' function

Question

String date in the format "dd-MM-yyyy" cannot be transformed into a date using the 'DatePipe' function

Having trouble with date conversion in my custom pipe. It seems that when using a locale of 'nl-nl' and trying to format the date as 'dd-MM-YYYY', I'm seeing an error message stating

Unable to convert "16-02-2023" into a date for pipe 'DatePipe'

, while other dates like 02-09-2023 work fine.

import { DatePipe } from '@angular/common';
import { Pipe, PipeTransform } from '@angular/core';
import { ConfigurationService } from '../services/configuration.service';

@Pipe({
    name: 'formattedDate',
})
export class FormattedDatePipe implements PipeTransform {
    constructor(
        private datePipe: DatePipe,
        private configurationService: ConfigurationService,
    ) {}

    transform(value: Date | string | number): string {
        return this.datePipe.transform(value, this.configurationService.config.customer.dateFormat);
    }
}

I suspect there may be confusion between day and month values causing the issue, but I haven't been able to pinpoint the exact cause.

Answer №1

import { DatePipe } from '@angular/common';
import { Pipe, PipeTransform } from '@angular/core';
import { ConfigurationService } from '../services/configuration.service';

@Pipe({
    name: 'formattedDate',
})
export class FormattedDatePipe implements PipeTransform {
    constructor(
        private datePipe: DatePipe,
        private configurationService: ConfigurationService,
    ) {}

    transform(value: Date | string | number): string {
       
        return this.datePipe.transform(value, 'dd-MM-yyyy', 'nl-nl');
    }
}

In order to rectify the issue at hand, it is crucial to ensure that the date format being utilized corresponds with the norms of the 'nl-nl' locale. Within the Netherlands, the customary date structure typically follows 'dd-MM-yyyy,' wherein the year is denoted in lowercase as 'yyyy,' rather than uppercase as 'YYYY.' By conforming to these guidelines, potential errors stemming from date formatting within a Dutch context can be mitigated effectively.
