Full-stack deployment with Heroku

Hi, I have been working through the Full-Stack course and on the deploying a full-stack application to Heroku, you now encounter an issue due to them no longer having the free tier option. After a few attempts of rewriting part of the code, I have managed to link the database to Supabase, rather than paying for Heroku’s Postgresql.
The link to my updated code for this is GitHub - 777Jaylee777/deploying-fullstack-with-heroku-sample: Deploying a full-stack application with Heroku
Hopefully this helps people who get stuck like me.
