Support for syntax error overlay

[jrysig]

Is it possible to support syntax error overlay in webpack-bundle?
It is implemented in webpack-hot-middleware: webpack-contrib/webpack-hot-middleware#9
or Create React App: facebook/create-react-app#744

I did try to use webpack-error-notification plugin but error overlay displayed directly in browser seems like better solution.

First one, as I understand, is not compatible with webpack-dev-server, which does many more things than just hot-reloading, so taking it out and rolling out some alternative seems overkill for overlay notifications.
Second one does not come as separate component and is React specific.

Currently webpack-dev-server client displays errors in console. Maybe some abstract solution to show any console error as a browser notification etc. would be a solution?

Webpack-dev-server gives socket to listen to events (this is done by webpack-dev-server client), but I'm not sure whether it would clash with client or could work as a separate, additional library.

webpack-dev-server supports this from 2.3 version. Webpack 2 default configuration enables this automatically - just update the bundle (see upgrade.md) and run maba:webpack:setup to update package.json and webpack configuration.
