Need help with dash app deployment on Heroku with postgresSQL

using this connection URL with SQL Alchemy package, need help in knowing steps to change to deploy app on Herouku

con = postgresql+psycopg2://postgres:1234@localhost/demo

This doesn’t sound like a Dash question but rather one about SQLAlchemy. Perhaps try posting your question on Stack Overflow, where you might have more chances of getting help.
