Small addition, for some vuejs, I need to pass data on the mount method, but those date need to be available before the  '/js/app.js', if not I can't access the data.

For instance in a create/edit/index.blade.php I have

@section('scripts-before')
    <script>
      window.Etablissements = {
        villes: {!! json_encode($data) !!},
      };
    </script>
@stop
