Any documentation/info on handling async?

[zcrowe]

I'm trying to delete a file from Amazon s3 just before a collection item containing a reference item to it is removed from a collection.

I'm using: https://github.com/Lepozepo/S3 to handle the s3 side.

What's the best way to handle the async aspect of dealing the file within the hook: Collection.before.remove(function (userId, doc) {}

Any pointers much appreciated :)

Just call your async code in the hook. If you want to be sure that the doc is removed, do it in an after hook
