Let's say I want to open-source a thing, but it has stuff like Auth0 integration and Postgres db with a bunch of stuff in it. Should I somehow extract the "core" and keep the rest closed-source? But I feel like that would make the whole project less usable.

@latviancoder Of course it depends on the project but I would either provide a database schema/migrations with an abstract auth layer like next-auth or release the core as open source and provide a closed-source demo. Some setup docs are necessary in any case.
