Stubs the @emotion/core types, which are only used internally by Storybook, but cause type errors if included.

Maybe Storybook should use a dedicated tsconfig.json instead of polluting the base global config?

EUI PRs like this have highlighted the need to make better use of the various tsconfig files, especially for browser vs. node environments. @mistic and @spalger are aware, but I'm not sure if there is an issue tracking the idea.
Note that this is a temporary change that can be reverted when Storybook moves to Emotion 11. I'm happy to make further changes, though, if y'all decide that kbn-storybook should be handled differently.

If @elastic/kibana-operations team thinks it's acceptable... @mistic any actionable items for the problem?

Opening this up for discussion. Note that there are a couple tasks still to complete, but the foundation is ready for review. |

Is there a useful error message if a developer tries to use styled-components outside these directories?

Not currently, but if the ops folks agree that this opt-in/opt-out approach is the right way to go, we can look at adding a message.

Is the plan to discouraging use of styled-components and push the teams working on these plugins to migrate to emotion?
What if we added an eslint error message for importing styled-components that told people to use @emotion/react instead. Then people would need to disable the eslint rule when importing it which I think is ideal if we're actively discouraging the spread of styled-compononents. We could also have the opposite rule in place and maintain this list of selectors in .eslintrc.js or something so they stay synchronized.
(This is quite a list of plugins already using styled-components though, didn't expect it to be so large)

Yes. The APIs are similar enough that migration shouldn't be time consuming. I was also surprised to see so many plugins using it; the list has grown since I last did an audit.
Good ideas regarding eslint. I'll look in to creating a rule and some kind of synchronizable list.

Great, I think since we're going to need to scope this to specific files we might want to customize the @kbn/eslint/module_migration rule: https://github.com/elastic/kibana/blob/master/packages/elastic-eslint-config-kibana/.eslintrc.js#L37-L41
We can add file globs to include/exclude specific migration mappings for specific patterns using regex like above. Should be as simple as filtering the list of mappings and then returning an empty visitor {} when the mappings are empty.

Should we create a meta issue with an explicit deadline to track the migration process?

Finally got back to this. Extended @kbn/eslint/module_migration to accept include and exclude and used that to write a new rule for styled-components. The file regex array used by @kbn/babel-preset is now stored in @kbn/dev-utils and is shared across packages.

Have you created a meta issue to ping codeowners of these plugins to migrate from styled components?

I have not. Thanks for the reminder
