Doesn't work with "modern" transpilation

[marcins]

I am building my code using @babel/preset-modules, this plugin fails to parse on default exports without a class name when they're not being transformed by Babel. That is, components that look like this:

export default class extends Component {}

I looked at adding some failing tests and fixing the plugin but it looks like it hasn't been updated for awhile and is still based on Babel 6, so would likely require some maintenance as well.

If it were up to me, I would probably:

• update the test suite to build both modern and ES2015 code in the tests
• maybe move to Jest in order to take advantage of snapshots?
• update the plugin for Babel 7

Happy to help with a PR if there's appetite for this change.

Hi @marcins, I wrote a Webpack plugin that will detect React components defined in this way and emit a displayName property. You can find it here: https://github.com/runreflect/webpack-react-component-name
