fonk-nif-validator

This is a fonk microlibrary that brings validation capabilities to:

• Validate if a field of a form is a valid NIF (DNI, NIE and/or CIF)

How to install it:

npm install @lemoncode/fonk-nif-validator --save

How to add it to an existing form validation schema:

We have the following form model:

const myFormValues = {
  providerCIF: 'P9316179B',
  clientDNI: '31016922L'
}

We can add a nif validation to the myFormValues

import { nif } from '@lemoncode/fonk-nif-validator';

const validationSchema = {
  field: {
    providerCIF: [
      {
        validator: nif.validator,
        customArgs: { validTypes: [nif.types.CIF] },
      },
    ],
    clientDNI: [
      {
        validator: nif.validator,
        customArgs: { validTypes: [nif.types.DNI, nif.types.NIE] },
      },
    ],
  },
};

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 { nif } from '@lemoncode/fonk-nif-validator';

nif.setErrorMessage('El campo debe de ser un DNI válido');

• Locally just override the error message for this validationSchema:

import { nif } from '@lemoncode/fonk-nif-validator';

const validationSchema = {
  field: {
    providerCIF: [
      {
        validator: nif.validator,
        customArgs: { validTypes: [nif.types.CIF] },
        message: 'Error message only updated for the validation schema',
      },
    ],
    clientDNI: [
      {
        validator: nif.validator,
        customArgs: { validTypes: [nif.types.DNI, nif.types.NIE] },
        message: 'Error message only updated for the validation schema',
      },
    ],
  },
};
