Do you have any docs about __FEDERATION__

[haimrait]

Do you have any explanation or documentation about the federation instance that is added to the window object? Also, what is the difference between federation.instances and federation.share?

[YanPes]

• __INSTANCES__ contains all your actual remotes loaded on the host including all meta data.
• __SHARE__ is exposing all found shared dependencies you define in your "share scope" (bundler.config) on top level of __FEDERATION__
  This can be useful to debug if unwanted shared dependencies slipped in your environment

Each runtime, be it host or remote is a "instance" the first instance is usually the host system since it's initialized first then loads remotes and initialized them.

Share is the share scope. It's where the agreed upon shares or avaliable shares are written to. In v1 you'd know it as webpack_share_scope variable.

There should be no reason to ever mutate share directly. Rather we would mutate the shares on the instances who also have the meta data and that is also where runtime plugins are pulling info from.
