requiredDefined

requiredDefined<T>(path, option?): void

Defined in: projects/ngx-signal-schema/src/lib/validators/required-defined.ts:26

Validator that ensures a value is defined (not null or undefined).

Important: Use this validator primarily for non-string types where false, 0, or empty arrays are valid and intentional selections. For string/text inputs, use requiredTrimmed instead.

This is particularly useful for boolean fields (checkboxes, toggles) where the standard required validator might treat false as a missing value (falsy). This validator explicitly checks that a value is present, regardless of whether it is true or false.

Type Parameters

Parameters

path

SchemaPath<T>
