Improve error messages

[davidnaas]

Currently when developing and something is wrong in a component i get the following error:

bundle.js:8859 Warning: React.createElement: type should not be null, undefined, boolean, or number. It should be a string (for DOM elements) or a ReactClass (for composite components). Check the render method of `AppContainer`.

bundle.js:8400 Uncaught Invariant Violation: Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: object. Check the render method of `AppContainer`.

It's incredibly hard to find the actual error which usually is something simple. It would speed up development a lot if it was possible to make the error messages more explicit.

After a brief investigation I've come to the conclusion that it's the hot reloading causing it. Reverting that commit brings back normal error messages.

hmm, I wonder if we can catch and fix that

[davidnaas]

Not sure how. I'm no expert in webpack and hot reloading I'm afraid

[kenwheeler]

I'll look into it

Closing, as this is react reporting unrelated to this library
