AsyncValidator

Validator marked by asyncValidator() for asynchronous scheduling and cancellation.

Import

import type { AsyncValidator } from '@ngblocks/form-nodes';

When to use it

Use for the marked result of asyncValidator(). A plain function returning a Promise is not a substitute for configuring a validator through the helper.

Declaration

type AsyncValidator<TValue, TField extends AnyNode = AnyNode> = (context: ValidatorContext<TValue, ValidatorApi<TValue>, TField>) => ValidationResult;

Type parameters

Parameter	Constraint	Default
TValue	Unconstrained	Required
