Could you elaborate on that please? Is it impossible to skip Babel when using React Native?

(Last time I checked Flow npm package gives you binaries.)

I'm sure Flow installs fine in "standard" environments, like an OSX laptop. I was thinking about more weird places, like CI servers where you can't fully control the environment. I was burned enough about stuff like that in the past.

Yes, the React Native packager depends on Babel, and uses a react-native preset. When you start a new project, you get this default .babelrc:

    {
      "presets": [
        "react-native-stage-0"
      ]
    }

They basically wrote their own version of webpack, to solve some performance problems and make development as fast as possible.

Ah, I see. Well, I'm sure it's common enough that you would have no problems getting it running on CircleCI and TravisCI.

Here's the only issue I found, which is now closed: https://github.com/flowtype/flow-typed/issues/247

Sure! I'll just note there are more CI systems than CircleCI and TravisCI. Especially on premise and on older distros.
