strong_migrations VS data-migrate

In the Rails world, the gem strong_migrations can be used to detect these: https://github.com/ankane/strong_migrations

The docs include a handy articulation of fixes.

gem "strong_migrations" - https://github.com/ankane/strong_migrations | Helps devs write non-blocking migrations, a must-have.

Frameworks will have a preferred solution. We use Rails with the strong_migrations gem which is great: https://github.com/ankane/strong_migrations

There’s no real way to test, but you can use gems like https://github.com/ankane/strong_migrations and not allow to merge branches unless they are up-to-date with main.

The strong migrations gem in Rails alerts when you're trying to make a migration that may be dangerous. Does anyone know an alternative for Javascript? Or maybe for raw SQL.

Half of the problems in this article are migration related.

I am extremely grateful that some people have created awesome libraries like strong migrations https://github.com/ankane/strong_migrations. Even if you are not using rails, bookmark its readme, it is an awesome cheat-sheet when writing a migration.

I would suggest taking a look at strong migrations[1]. It's a rails project, but the readme does a great job explaining what it checks for and what safe alternative to use instead. I still link to their explanations in PRs for non-rails projects.

For example, take the popular data-migrate gem. Its gemspec requires activerecord >= 6.1 with no upper bound. Looking at the changelog, though, you'll see that support for Rails 7.1 wasn't added until version 9.2.0. Older versions will hit this exception when someone tries to run migrations under the latest Rails, even though bundler installs the package with no warning.

The third option is to use the data-migrate gem.

I was thinking of this one, I believe, but it's pretty old:

This is maybe a more modern one I found:

https://github.com/ilyakatz/data-migrate exists for exactly this purpose with a similar approach as active record migrations.

Data migration gem There are a couple of gems that helps organize your data migrations in the same way as schema migrations, one of the most known data-migrate. You can simply generate a new migration:

In the past, we've used data-migrate for this, but this comes with pitfalls. What happens if the deploy fails? We can often end up with strange errors and changes in state, so it's nicer to have a bit more control.
