Bug - runtime error in webpack 2.2.0-rc.4 and later

[echenley]

See babel/babel#5155

Basically:

// works
type Props = {}
export type { Props }

// breaks
export type Props = {}

I believe this is the Webpack change which breaks this behavior: webpack/webpack#3755. module.exports is now undefined when using ES6 modules.

This output is therefore invalid: https://github.com/brigand/babel-plugin-flow-react-proptypes/blob/master/src/__tests__/__snapshots__/export-object-test.js.snap

@echenley we could skip exporting the types when exports is undefined. Is that sufficient? I don't want to generate es6 modules, except maybe behind a config flag.

[echenley]

Yeah, that works as long as users don't expect to be able to import proptypes when using this plugin? It seems very unlikely that anyone is relying on this:

import { babelPluginFlowReactPropTypes_proptype_Props } from './SomeComponent'

[brigand]

Yeah, the incredibly long name and lack of documentation discourages use :-)

Published a fix as 0.20.0. Let me know if you have any more issues.

Perfect, thank you!
