Migrations you don't write by hand

Enobase was a friend's early-stage startup. Between missions, I jumped in to build a piece of internal tooling the team kept tripping over.

Their database schema was declared in code, but the actual database drifted from it, and reconciling the two with hand-written migrations was tedious and easy to get wrong.

What shipped

Tooling that detects the changes made to the declarative schema and generates the corresponding TypeScript migrations for it — typed end to end with Kysely, so a schema edit turns into a reviewable migration instead of a manual chore.

Result

Schema changes stopped being a source of drift and foot-guns: the diff is the migration, and it's generated, typed and reviewable by default.
