A validation function for a String Field

Enforces that a field is not empty

Enforce that a field is an email.

The format the email just follow is:

[ >1 upper,lower,digit,symbol ]@[ >2 upper,lower,digit,symbol ].[ >2 upper,lower,digit, ]

To validate emails, we don't use regex we use elm-tools/parser to validate. If there's a specific format you need your emails to follow, you can easily implement your own validation function.

Enforce that a field contains only numbers.

Enforce that a field does not contains only numbers.

Enforce that a field is at least x characters long

Enforce that a field is at most x characters long

Enforce that a field is exactly x characters long
