Migres

This package provides simple migration capabilities for any backend.

System requirements

Basic usage

The key type in this package is Module which allows mapping version strings to Migration interfaces. For example:

import "github.com/annybs/migres"

type MyBackend struct{}

func (mb *MyBackend) Module() migres.Module {
  return migres.Module{
    "1.0.0": migres.Func(mb.upgradeV1, mb.downgradeV1),
    "2.0.0": migres.Func(mb.upgradeV2, mb.downgradeV2),
  }
}

Call Module.Upgrade(from, to) or Module.Downgrade(from, to) in order to execute migrations. The module ensures migrations are all run in the correct order.
