Function useShinyOutputValue

useShinyOutputValue<T>(
    outputId: string,
    defaultValue?: T | undefined,
    options?: { namespace?: string | null },
): T | undefined
Hook to subscribe to a Shiny output value.

Returns just the current value. Use this when you only need the data — which is most call sites. If you also need the lifecycle status (to drive a skeleton, spinner, or error UI), call useShinyOutputStatus alongside it.

  Optional configuration object.
  - Optionalnamespace?: string | null

The current output value.
