Example from the command line for monorepo with a frontend and backend app.

backend app (python)

create the app, add the buildpack, and set the app directory environment variable

heroku create -a myproject-backend
heroku buildpacks:add -a myproject-backend https://github.com/AMStrix/heroku-buildpack-mono-apps
heroku config:set -a myproject-backend APP_DIR_HEROKU=backend

create Procfile-backend and .buildpack-backend settings files in the root

# in monorepo root directory
printf 'web: cd backend && gunicorn my.app:create_app\(\) -b 0.0.0.0:$PORT -w 1' > Procfile-backend
printf "https://github.com/heroku/heroku-buildpack-python" > .buildpack-backend
git add .
git commit -m "add heroku procfile and buildpack settings for backend"
