This PR introduces an optional argument
whitespace
to therequired
validation rule.The parameter has a default value
'pre'
which means that the validator will preserve the whitespace in the input and any strings that are only whitespace will pass the validation.It supports a value
'trim'
which trims the whitespace and then the validator evaluates the result. A whitespace only string would not pass the validation in this case.Note: This only affects the validations, the original input is not modified.
Bonus: This PR also introduces
cross-env
and updates the test script accordingly.
