useValue() function

Subscribe to a single read-signal and return its current value: a signal, a computed, a Field, a Form or a FieldArray. The component re-renders when the value changes, as options.isEqual (defaultObject.is) decides. Built on useSyncExternalStore.

Signature:

export declare function useValue<T>(signal: ReadSignal<T>, options?: UseValueOptions<T>): T;

Parameters

Parameter	Type	Description
signal	ReadSignal<T>
options	UseValueOptions<T>	(Optional)

Returns:

T

Example

function Count({ count }: { count: ReadSignal<number> }) {
  return <span>{useValue(count)}</span>
}
