fonk-is-credit-card-validator

This is a fonk microlibrary that brings validation capabilities to:

• Validate if a field of a form is a valid credit card

How to add it to an existing form validation schema:

We have the following form model:

const myFormValues = {
  clientId: 1,
  creditCard: '375556917985515'
}

We can add a isCreditCard validation to the myFormValues

import { isCreditCard } from '@lemoncode/fonk-is-credit-card-validator';

const validationSchema = {
  field: {
    creditCard: [isCreditCard.validator],
  },
};

You can customize the error message displayed in two ways:

• Globally, replace the default error message in all validationSchemas (e.g. porting to spanish):

import { isCreditCard } from '@lemoncode/fonk-is-credit-card-validator';

isCreditCard.setErrorMessage(
  'El valor debe de ser un número de tarjeta de crédito válido'
);

• Locally just override the error message for this validationSchema:

import { isCreditCard } from '@lemoncode/fonk-is-credit-card-validator';

const validationSchema = {
  field: {
    creditCard: [
      {
        validator: isCreditCard.validator,
        message: 'Error message only updated for the validation schema',
      },
    ],
  },
};
