library0.3.5jsnpmunverified

A module for detecting differences between database states and migration files, designed to work with db-migrate. Version 0.3.5 (latest) provides CLI tools to compare applied migrations against pending ones, helping identify missing migrations or drift. It supports multiple reporters (default, ghost) and environments (dev, production). Unlike db-migrate's built-in diff, it offers explicit detection and reporting. Release cadence is low; no updates since 2017.
