Me personally, I'd love to see a video guide from the bare beginning showing off how to install postgresql, prisma, connecting those two, creating 3-4 models with relations. This is all incredibly explained in the docs but seeing something like this in action especially since there are zero to none proper videos on the topic, would mean so much to beginner-intermediate developers just getting into Prisma.
Another more daunting subject that definitely needs a video explanation (in my humble opinion) is Migrations. Best practices to avoid schema drifts, what and how to use migrations in development and in production. Even though this is all documented, someone who has never worked with migrations will have to make huge mistakes in production to learn these things, mistakes that could be avoided.
Those are just my 2 cents, thank you for listening to my Ted Talk π
