Meyer

Meyer is a database migration tool for Node.js (v18+) with inversion of control via pluggable DBMS adapters. Version 1.2.5 is stable with infrequent releases. It supports sequential plain SQL migrations with explicit UP/DOWN sections, automatic rollback in development mode when prior migrations are modified, and a design that decouples migration logic from any specific database driver. Unlike other migration tools, Meyer requires you to install a separate DBMS package (e.g., meyer-dbms-knex or meyer-dbms-mssql) and provides TypeScript types.
