Django session variable in JavaScript

In Views.py Add:

class SessionVarView(TemplateView):

    permission_classes = [permissions.IsAuthenticated]    

    @csrf_exempt

    def get(self, request, *args, **kwargs):

        print(request)

        return HttpResponse(request.session[kwargs['key']])

In Urls.py Add:

    re_path(r'^session/(?P<key>[^/]+)$', views.SessionVarView.as_view(), name='session-var'),

Then you could get it from JS via http://127.0.0.1/session/key_name_here or something similar.
