ObservableLike

Framework-neutral subset of an Observable accepted from asynchronous validators.

Import

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

When to use it

Use for an async source compatible with the library without depending on RxJS types. Honor subscription cleanup so cancelled validation stops its work.

Declaration

type ObservableLike<TValue> = {
    subscribe(observer: ObserverLike<TValue>): SubscriptionLike;
};

Type parameters

Parameter	Constraint	Default
TValue	Unconstrained	Required

Declared members

The declaration above also includes inherited contracts and overloads where applicable.

Member	Meaning
subscribe	Subscribes the validation observer and returns a handle used for cancellation and cleanup.
