Nested object

// Default delimiter is '__' (double underscore)
const config = envToObject(
  {
    BELT__CONTACT__NAME: 'John',
    BELT__CONTACT__AGE: '25',
    BELT__CONTACT__IS_OK: 'true',
  },
  {
    convertKey: key => key.toLowerCase(),
  }
);
// config => { belt: { contact: { name: 'John', age: 25, is_ok: true } } }

// With a custom delimiter '.'
const config = envToObject(
  {
    'BELT.CONTACT.NAME': 'John',
    'BELT.CONTACT.AGE': '25',
  },
  {
    convertKey: key => key.toLowerCase(),
    nestedDelimiter: '.',
  }
);
// config => { belt: { contact: { name: 'John', age: 25 } } }

// With a custom delimiter RegExp
const config = envToObject(
  {
    'BELT.CONTACT_NAME': 'John',
    'BELT.CONTACT@AGE': '25',
  },
  {
    convertKey: key => key.toLowerCase(),
    // Every non-alphanumeric character
    nestedDelimiter: /[^a-zA-Z0-9]/,
  }
);
// config => { belt: { contact: { name: 'John', age: 25 } } }
