I’ve been using Prisma for a while and I quite like it. Best ORM for TypeScript I’ve used. My biggest issue with it is testability. Sure, I can mock the Prisma client in tests with Jest or something, but if I want to test state I pretty much have to reimplement an in-memory DB using JS mocks. I can also connect to a real DB made for testing but it’s quite overkill, I’m usually not interested in testing Prisma itself, just my own code. I wish Prisma had test mode, where you could replace the client with a temporary in-memory SQLite DB without writing tons of boilerplate.

A drop-in replacement for PrismaClient for tests would have been wonderful.
