Pushit

Quick demo to demonstrate the use of firebase web push notifications with the use of javascript on frontend, django on backend and push notifications via fcm-django pypi package for django.

Quick start

prerequisites

• in pushit:
  • create virtual environment with python -m virtualenv env (or python -m venv env in Python 3)
  • activate virtual environment with . env/bin/activate
  • install necessary Python packages with pip install -r mysite/requirements.txt

frontend

• in pushit/frontend:
  • run server with python -m http.server 8001

backend

• in pushit/mysite:
  • run database migrations with python manage.py migrate
  • create Django administrator with python manage.py createsuperuser
  • collect static files with python manage.py collectstatic
  • run server with python manage.py runserver 0.0.0.0:8000.

how to use

• open http://localhost:8001 in your browser of choice
• request token and allow firebase to send notifications to your browser (device)
• you should now be seeing your instance id token on the aforementioned URL
• if you go to django admin, http://localhost:8000/admin/fcm_django/fcmdevice/, you should be seeing a FCMDevice instance for your browser
• send yourself a test notification with django admin actions
  • shell example (run python manage.py shell from pushit/mysite):

       from fcm_django.models import FCMDevice
       device = FCMDevice.objects.all().first()
       device.send_message(title='title', body='message')

• Enjoy! :)

optional HTTPS support

• why would you want to do this? because service workers will not work on http, unless you are running them on localhost
• generate certificate and key with openssl req -nodes -new -x509 -keyout key.pem -out cert.pem in pushit
• in pushit/frontend:
  • update URL protocol to https and localhost to your server's IP address in index.html
  • run frontend server with python server.py
• in pushit/mysite:
  • add your server's IP address to allowed hosts in project settings (shell example: echo "ALLOWED_HOSTS = ['172.20.1.10']" > mysite/local_settings.py)
  • run backend server with python manage.py runsslserver --certificate ../cert.pem --key ../key.pem 0.0.0.0:8000
• testing this demo in Chrome may require to run it with --ignore-certificate-errors flag to avoid SSL certificate fetch errors
• during the testing allow untrusted connections to the demo servers on browser prompt
