PropTypes are not removed from inherited classes

Yeah, that's actually a design decision, have a look at #8

It's also taking a side by only accepting React.Component and Component as class names.
Anything else, like BaseComponent, won't be optimised.

Ah, I see, thanks for the pointer!

So does it mean that Babel doesn't allow to traverse up the inheritance chain at all or it's just current limitation of the plugin?

The thing is, I can't remove the propTypes from any class. I should only do it on a React class component.
I need a heuristic to do so. I relying on the React.Component and Component class names.
That works great in +90% of the cases.
For your specific cases, we could also be looking for a render method and assert that this method is returning a React element.

TL;DR The quick win is to rename your Parent class. The right way to fix this issue would be to improve the heuristic.

P.S. Notice that using inheritance is considered a bad pattern in React. I would rather use composition.

This issue is quite old. I haven't seen more need for it. I'm closing it. Thanks for raising your voice.
