# `PhoenixKitPhotos.Components.ViewerPicker`
[🔗](https://github.com/BeamLabEU/phoenix_kit_photos/blob/v0.3.0/lib/phoenix_kit_photos/components/viewer_picker.ex#L1)

A select for the viewer of one library (`PhoenixKitPhotos.Viewer`): "Default", "Swipe
viewer", "Classic viewer". It shows nothing to someone who may not choose
(`Viewer.can_set?/2`), and checks again when it saves.

## Usage

    <.live_component
      module={PhoenixKitPhotos.Components.ViewerPicker}
      id="viewer-picker"
      library_uuid={library_uuid}
      auth={scope}
    />

When the choice is saved the parent LiveView gets `{:viewer_changed, library_uuid}` and
reads `PhoenixKitPhotos.Viewer.for_library/1` again.
