@machour Curious - Why is jokes archived and "won't be touched". The prod build currently fails with:

➜  _official-jokes git:(main) npx prisma migrate deploy

@imaitland This is a decision made with Brooks over discord, without being aware of the issue you're posting. Thank you for bringing it to our attention 🙏🏼

The idea was that the jokes tutorial was retried from the documentation, and we weren't interested in maintaining a legacy Remix v1 app.

CC'ing @brookslybrand to have a new look at this decision. Maybe we could spend some time fixing the example, or just add a note in its README stating that it's archived, and why.

Yep, that is correct. Someone is definitely welcome to submit a PR to fix the issue for anyone who still finds the tutorial useful, but since it is not the official tutorial the Remix team is not focused on moving it to v2.

I do like the idea @machour of adding a note to the README about why it is archived
