yarn db:greenfield

yarn db:greenfield executes tsx scripts/mikro-modules.ts greenfield. It is designed for development only when you want to rebuild the schema from scratch.

Usage​

yarn db:greenfield

What the Command Does​

  1. Cleans every module’s migrations/ directory by deleting generated migration .ts files and snapshot JSON files.
  2. Removes checksum files under the repository’s /generated folder.
  3. Drops per-module MikroORM migration tables (mikro_orm_migrations_<module>).
  4. Drops all tables in the public schema of the database referenced by DATABASE_URL.
  5. Regenerates fresh migrations for every enabled module by internally calling the generate mode.
  6. Applies the newly generated migrations immediately.

Safety Considerations​

  • The command irreversibly wipes the target database. Never run it against production or staging environments.
  • Ensure DATABASE_URL points to a disposable database before executing.
  • Because it removes migration files, you may want to stash or commit any pending migration work beforehand.

Suggested Workflow​

  1. Stop any dev servers using the database.
  2. Run yarn db:greenfield.
  3. Optionally execute yarn init to reseed data and example content.

Troubleshooting​

  • Permission errors when dropping tables — verify the database user has privileges to drop tables and alter replication roles.
  • Migrations fail after regeneration — inspect generated migration files and adjust entity definitions accordingly, then re-run yarn db:greenfield or yarn db:migrate.
