creditCard

The value must be a valid credit card number — 13–19 digits (spaces and dashes allowed) passing the Luhn checksum.

Signature​

NguardValidators.String.creditCard: ValidatorFn

Reactive forms​

import { FormControl } from '@angular/forms';
import { NguardValidators } from 'ng-nguard';

new FormControl('', [NguardValidators.String.creditCard]);

Template-driven forms​

<input ngModel name="card" nguardCreditCard />

{ creditCard: true }

Notes​

  • Spaces and dashes are stripped before validation. Only the length + Luhn are checked — not whether the card network/BIN is real.
