Drizzle

@branchly/migrator-drizzle drives Drizzle Kit: it fingerprints your generated SQL migrations, applies them with drizzle-kit migrate, and runs your seed command on fresh databases.

Configuration

migrator: {
  use: 'drizzle',
}

Option	Default	Meaning
migrationsDir	'drizzle'	Where your generated .sql migrations live.
seed	(none)	Seed command (e.g. 'tsx src/seed.ts'). Skipped when unset.
applyCommand	'npx drizzle-kit migrate'	The command used to apply pending migrations.
urlEnv	'DATABASE_URL'	The env var the apply/seed commands receive the connection under.

Behavior

• Fingerprint — a hash of the .sql file names in migrationsDir. Branches with identical migration sets share snapshots.
• Apply — drizzle-kit migrate applies only pending migrations, satisfying the kernel’s idempotency requirement.
• Seed — your configured command, run with the branch connection injected as urlEnv, on freshly built databases only.

Works with any of the datasource adapters — PostgreSQL, MySQL, or SQLite.
