Questions tagged [golang-migrate]

golang-migrate is a database migration tool written in Go. Questions tagged golang-migrate should be directly related to database migrations in Go.

See https://github.com/golang-migrate/migrate

Database migrations written in Go. Use as CLI or import as library.

  • Migrate reads migrations from sources and applies them in correct order to a database.
  • Drivers are "dumb", migrate glues everything together and makes sure the logic is bulletproof. (Keeps the drivers lightweight, too.)
  • Database drivers don't assume things or try to correct user input. When in doubt, fail.
