Tips

Run Mongodb as Service (Mac)

In development/production, it may be desirable to have MongoDB running in the background as a service.

If you have MongoDB installed using Brew, you can use this command:

brew services start [email protected]

Otherwise, just google around on running MongoDB as a service.

Run Flask Production Server Using Gunicorn

For this project, Gunicorn was chosen as a production server. A Gunicorn config file is provided in the Backend folder.

To run:

cd backend
gunicorn -c gunicorn.conf.py backend:app

You may also want to investigate running the Gunicorn script on startup as a service.

SSL in Production

As the Frontend requires access to the microphone, browsers will need to run in a secure context, i.e over HTTPS.

In development:

Localhost is excluded from this requirement. To test other domains, you can use a flag in Chrome to get around this:

In production:

One solution is to create a self-signed SSL certificate to use with the Apache server for the Frontend, and with Gunicorn for the backend.
