UUID

UUID modifier

A modifier which creates a validation rule to ensure that a given string is a valid UUID (Universally Unique Identifier).

Schemas

Arguments

  • message? - A custom object with error messages to be displayed when validation fails or there are type errors

Example

import { uuid, string } from '@nordic-ui/validathor';
 
const uuidRule = string([
  uuid({
    type_error: "Must be a valid UUID",
  }),
]);
 
try {
  const parsedValue = uuidRule.parse('123e4567-e89b-12d3-a456-426614174000');
  console.log('Parsed value:', parsedValue);
} catch (error) {
  console.error('Parsing failed:', error.message);
}

Supported UUID Versions

The UUID modifier validates UUIDs according to RFC 4122, supporting:

  • Version 1 (timestamp-based)
  • Version 2 (DCE Security)
  • Version 3 (namespace name-based, MD5)
  • Version 4 (random)
  • Version 5 (namespace name-based, SHA-1)

The validation is case-insensitive, accepting both uppercase and lowercase UUIDs.
