# This example builds https://isso-comments.de. It's meant as a relatively
# simple demonstration on how to build applications consiting of a python
# backend and a javascript frontend, built with nodejs.
#
# To actually run an isso server with this, you'd also need a configuration file,
# see https://posativ.org/isso/docs/configuration/server/
