SqliteMigrator.ts

SqliteMigrator.ts overview

Runs database migrations for Bun SQLite projects that use Effect SQL.

This module re-exports the shared migration loaders and errors, then provides run and layer helpers that apply pending migration files with the current SqlClient. It does not add Bun-specific schema dump support; migration execution is handled by the shared SQL migrator.

Since v4.0.0
