 Drizzle ORM is a TypeScript ORM for SQL databases designed with maximum type safety in mind. It comes with a [drizzle-kit](https://github.com/drizzle-team/drizzle-kit-mirror) CLI companion for automatic SQL migrations generation. Drizzle ORM is meant to be a library, not a framework. It stays as an opt-in solution all the time at any levels.

-The ORM main philosophy is "If you know SQL, you know Drizzle ORM". We follow the SQL-like syntax whenever possible, are strongly typed ground up and fail at compile time, not in runtime.
