Steps for setting up backend server

1. Install python dependencies, assuming that you have pip already setup.

pip install -r requirements.txt

2. Run the flask application using

python app.py

Now the backend is up and ready for serving requests.

I have used gunicorn as my WSGI server and nginx as reverse proxy on top of it.

To start the WSGI server at port 8000, execute the following command:

./start.sh

This shell file start the WSGI server at port 8000, nothing fancy

Steps for setting up Google Cloud Vision

Set the environment variable GOOGLE_APPLICATION_CREDENTIALS to the file path of the JSON file that contains your service account key.

export GOOGLE_APPLICATION_CREDENTIALS="[PATH]"
