-
Async
Relying on SQLx, SeaORM is a new library with async support from day 1.
-
Dynamic
Built upon SeaQuery, SeaORM allows you to build complex queries without 'fighting the ORM'.
-
Testable
Use mock connections to write unit tests for your logic.
-
Service Oriented
Quickly build services that join, filter, sort and paginate data in APIs.
