support passing an array of Migrations

[jedwards1211]

I want to rock the boat a bit: the current method of giving sequelize a directory and glob pattern to find migrations isn't very flexible, and neither are other options people have suggested (providing multiple directories, passing in an array of files).

I need to provide a way for plugins in my app to inject their own migrations that live in a different directory from the app core, and possible even use a mix of languages (coffee, typescript, etc).

thx, I will work through some more open PRs/Issues and then release a new version.

@jedwards1211 this is exactly what I need, except for one issue: the Migrations class isn't exported.

How are you getting at it? Do you do something hacky like directly require-ing migrations.js?

[jedwards1211]

@cjpark ah right. Yes, I was going to do it the hacky way like that. Though I ended up making code to copy migrations from various different folders into one temporary folder that I could use with Umzug as it is. (This is all to make our server support plugins that can provide their own database models and migrations)

When using an array of Migrations like this, there doesn't seem to be a way to pass custom params into the migration up and down functions. Or am I missing something?

[jedwards1211]

It's true that there's no way to do it via the options to Umzug, though whatever code you write to create the Migrations can wrap the up and down methods exported by your migration files to inject whatever custom params you want.
