This is a [fonk](https://github.com/Lemoncode/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:

```bash
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

```javascript
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):

```javascript
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:

```javascript
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',
      },
    ],
  },
};
```
