buildin

to build this goddamn thingie, run make SERVER_ADDRESS=https://...
e.g. make SERVER_ADDRESS=https://3ds.web.page/submit (this is not an actual valid url i hope)

hostin

app.py is a super small flask app that listens for post request on /submit, saves essential as essential_<discordname>.exefs and prints the discord username to stdout.
to retrieve an essential, you can use the retrieve api, which requires a password
you can set that password in config.ini
an example is provided, but needs to be renamed to config.ini obv
use gunicorn, e.g. gunicorn -w 1 app:app. I use venv to set stuff up:
python3 -m venv .venv
. .venv/bin/activate
pip install flask gunicorn flask_httpauth
gunicorn -w 1 app:app
