Drizzle ORM

Drizzle is a TypeScript ORM built around the idea that the query layer should not hide SQL. Schema is declared in TypeScript, queries are written with a chainable API that maps closely to SQL clauses, and the generated types flow from the schema definition rather than from a separate code generator pass. Migrations are produced by diffing the declared schema against the previous state. The tool emits plain SQL files, which means a migration can be read and edited before it runs. That is a deliberate contrast with ORMs that generate opaque migration steps, and it makes review of schema changes part of the normal pull request. The library supports Postgres, MySQL, SQLite, and the serverless variants of each, and it runs in edge runtimes because it has no dependency on Node-specific APIs. Teams that want an ORM but dislike losing the ability to reason about the emitted SQL tend to land here; teams that want a fully abstracted data layer with a large ecosystem of plugins may prefer a heavier framework.
