The Problem No One Talks About in Prisma APIs

# The Problem No One Talks About in Prisma APIs ... Prisma has made SQL database access in Node.js incredibly clean. Schemas are readable. Type safety is excellent. Queries feel intuitive. But after building a few real-world APIs with Prisma, I ran into a problem that no one really talks about. Not performance. Not migrations. Not relations. … ## Copy-Paste Is Easy. Living With It Isn’t. At first, duplication feels fine. But over time: - one endpoint allows invalid filters - another rejects them - one sorts on any column - another breaks if you try - one handles booleans correctly - another treats everything as a string Nothing is technically broken. But nothing feels solid either. … ## Helpers Don’t Actually Fix This The obvious move is a helper function. Most teams try it. Most teams regret it. Helpers tend to become: - too flexible to be safe - too strict to be reusable - hard to reason about - impossible to extend cleanly And many of them go one step too far — they **run the Prisma query for you**. … ## Strict by Default (And That’s the Point) Most bugs here don’t come from bad code. They come from: - unexpected query params - invalid filters - unchecked sorts Prisma Query Builder blocks those immediately. Not silently. Not later. **Immediately.** The API becomes predictable — not just for users, but for developers too.
