export default class

[jareware]

If you only have a single class in a file, it's convenient to export it during definition:

export default class ThreadListPanel extends React.Component {
  render() {}
}

Which will throw:

Error: /demo/app/ui/ThreadListPanel.js: We don't know what to do with this node type. We were previously a Statement but we can't fit in here?

Right, it's because the top level declaration (after which the displayName assignment should go) is then actually ExportDefaultDeclaration.

Thanks.
