db-diff

db-diff is a helper library built on top of the Prisma CLI for auto-generating and versioning customizable database migrations (compatible with Postgrator). By default, the library auto-generates both up and `down migrations when you run the command.

If you already have an existing Prisma schema in your project, run the following command

npm i --save-dev @ruheni/db-diff
npx db-diff

Optional arguments:

Option	Arguments	Default	Description
--schema		./prisma/schema.prisma	Path to your Prisma schema file.
--migrations-dir		./migrations	Path to your migrations directory. If the folder will be created if it doesnn't exist
--up			Generate only the up migration only
--down			Generate only the down migration only

Example usage:

npx db-diff --migrations-dir ./src/migrations

Generate only the up migration:

npx db-diff --up

Generate only the down migration:

npx db-diff --down
