./node_modules/fbjs/flow/lib

[options]
esproposal.class_static_fields=enable
esproposal.class_instance_fields=enable

module.name_mapper='^\(.*\)\.css$' -> 'react-scripts/config/flow/css'
module.name_mapper='^\(.*\)\.\(jpg\|png\|gif\|eot\|svg\|ttf\|woff\|woff2\|mp4\|webm\)$' -> 'react-scripts/config/flow/file'

Really old, but I found this today, two years ago, when I looking for flowconfig create-react-app on Google.
And I don't know if simply empty .flowconfig file is good enough config today.
I'm not sure if scanning entire node_modules is good way.
It looks that it takes time only at first run, so it should be fine to use empty `.flowconfig:

[ignore]

[include]
<PROJECT_ROOT>/src/
<PROJECT_ROOT>/server/

[libs]

[lints]

[options]
emoji=true

[strict]

And what folders should be under ignore? Could you please help with this @langpavel?
