sql-ddl-sync

Node.js library for synchronizing SQL DDL schemas across MySQL, PostgreSQL, and SQLite. Version 0.4.0 is the latest stable release (no longer actively developed). It is part of the ORM2 ecosystem, used to automatically create, alter, or drop database tables to match defined model collections. Key differentiator: it handles schema migrations without manual SQL, but lacks documentation and is tied to the ORM2 driver interface.
