Drizzle vs Prisma for a TypeScript app on Postgres
pick Drizzle ORM 0.45.2
Drizzle. The schema is TypeScript you can read, queries look like the SQL they become, the runtime adds about 20 KB with no engine to warm up, and migrations are plain SQL files you can review in a PR.
alternative · Prisma
Prisma has the more mature studio, a larger tutorial base, and generated types that beginners find easier.
Wins when your team is new to SQL and wants Prisma Studio and the generated client more than control over queries.
traps for Drizzle ORM (3)
| severity | versions | symptom and fix |
|---|---|---|
| major | >=0.30.0 | Two app replicas start at once and both run migrations; the second fails on an already-applied step. Run `migrate()` behind `pg_advisory_lock(<constant>)` in one process (a jobs container or a release step), never in every web replica's startup. |
| major | >=1.0.0-beta.1 | Installing `drizzle-orm@rc` pulls 1.0.0-rc.5 and SQLiteSyncDialect no longer exists. The 1.0 line splits SQLite into async and effect variants, removes `SQLiteSyncDialect` and `SQLiteAsyncDialect` in favour of `migrateSync` and `migrateAsync` under `sqlite-core/async/session`, and drops relational queries v1 from SQLite. The npm `latest` tag is still 0.45.2, so a plain install stays on the stable line; only the `rc` tag gets you 1.0. evidence |
| minor | >=0.30.0 | Selecting into a destructured tuple with `noUncheckedIndexedAccess` produces a type error on the first row. Read `rows[0]?.field ?? fallback` instead of destructuring `const [{ field }] = rows`. |
