@nestjs-crud/* ships four adapter services, one per supported ORM. They all extend CrudService from @nestjs-crud/core and follow the same WhereBuilder + QueryComposer + FetchHelper shape (see CONTRIBUTING.md — Adapter shape).

See Caching for the cache option details.

All four services give you:

• The eight generated routes from @Crud()
• @Override() for replacing any generated handler
• A strict field allowlist (v2.0.0): unknown sort, filter, or search fields throw RequestQueryException
• READ COMMITTED transactions wrapping updateOne, replaceOne, and deleteOne
• An optional LoggerService constructor argument (see Logging)

• TypeORM: most mature ecosystem, full feature parity with v1. The default for greenfield Postgres or MySQL projects with class entities.
• Drizzle: SQL-first and light, good when you care about type safety and bundle size.
• MikroORM: Unit-of-Work + identity map; reach for it if active-record ergonomics suit your team.
• Prisma: schema-first with a generated client. Pick this if you are already on the Prisma toolchain.
