Migrations? #94

Closed himat closed 1 year ago

Hi,

How do you recommend doing migrations with toucan? Are we supposed to use a separate library for that?

@himat I'm not a contributor, but I don't think this lib is scoped for migrations.

migratus is a library to handle migrations that works very well.

If I may https://gist.github.com/geraldodev/f4cc25376331ebd37d2eb8a4d3ccf8a9 mybatis migrations are sql based. This simple babashka script is meant to be placed on the root of the project, it will default the migrations to WhereUPutTheScript/migrations. it builds the classpath to invoke migrations, it downloads the dependencies (bb has a deps.edn like library) ./migrate.clj init ./migrate.clj status ./migrate.clj up ./migrate.clj down
