simple-flask-heroku-app

In a couple of minutes, deploy the simplest flask app that can be run on heroku server.

Two important things to notice

Here app:app is something similar to from app import app First app is written because of filename and second app is written because of the variable in the file which is our app to run by gunicorn
requirements.txt file is absolutely necessary for heroku to understand that this is python project

heroku logs -t -a <app_name> to view server logs continuously
heroku ps to see running thread/service
