This required option is the “max” value. Validation will fail if the given value is greater than this max value.

minMessage

type: string default: This value should be {{ limit }} or more.

The message that will be shown if the underlying value is less than the min option.

maxMessage

type: string default: This value should be {{ limit }} or less.

The message that will be shown if the underlying value is more than the max option.
