Min

Validates that a numeric value is at least a given minimum. Works with numbers and numeric strings.

Configuration

Config flag	Type	Description
`min`	`number`	Minimum accepted value.
`min`	`[number, string]`	Tuple form — the minimum plus a custom message.

const form = useForm({
  initialValues: { age: '' },
  validationSchema: {
    age: { min: 18 },
  },
});

With a custom message:

age: { min: [18, 'You must be at least 18 years old'] }

import { V } from 'formify-js';

V.min(18);

Scenario	Message
Value is below the minimum	`Must be at least 18` (the number reflects your value)

The check is inclusive: a value of exactly 18 passes min: 18.
Non-numeric values fail the comparison — pair with numeric or integer for clearer errors.
Use between to constrain both ends at once.
