• Attaches a client to a store: mounts its reducers and middleware, and registers its private slot on the store's client registry.

    Safe to call more than once for the same client — RTK deduplicates reducer injection, and re-registering a slot simply overwrites it with equal values.

    Type Parameters

    • S extends object = Record<string, unknown>

    Parameters

    Returns SdkStoreHandle<S>

    If handle is not a valid SDK store handle.
