# @device
The @device directive is used to specify a list of device types and to restrict components to run only on the marked (specified) devices. If the currently running device type doesn't match with any of the marked devices, the component with the device markers won't be resolved and calling getComponentByName() or querySelector will fail to retrieve the components.
