All the display goes without errors, but the logs. says this.

package.json
server.js

Procfile
Procfile.web
requirements.txt

The content for WSGI:

import os

from django.core.wsgi import get_wsgi_application

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "djangoynode.settings")

application = get_wsgi_application()

The content for Procfile:

web: bin/runsvdir-dyno

The content for Procfile.web:

django: gunicorn djangoynode.wsgi
node: node server.js
