if define a Component has componentDidUpdate, the 'why-did-you-update' will not work..

componentDidUpdate will override the original method, can we use createChainedFunction to link those function?

https://github.com/garbles/why-did-you-update/blob/master/src/index.js#L27

componentWillUpdate's SpecPolicy:
https://github.com/facebook/react/blob/master/src%2Fisomorphic%2Fclassic%2Fclass%2FReactClass.js#L242-258

how mixin work with SpecPolicy.DEFINE_MANY
https://github.com/facebook/react/blob/master/src%2Fisomorphic%2Fclassic%2Fclass%2FReactClass.js#L517-L519

Definitely aware of this. Thanks for making an issue.

we can inject code after instantiate (wrap mountComponent function and replace this._instance.componentDidUpdate when called mountComponent )
https://github.com/facebook/react/blob/master/src/renderers/shared/stack/reconciler/ReactCompositeComponent.js#L255

https://github.com/facebook/react/blob/master/src/renderers/shared/stack/reconciler/ReactCompositeComponent.js#L964

https://github.com/facebook/react/blob/master/src/renderers/shared/stack/reconciler/ReactCompositeComponent.js#L1012

but I don't know how to wrap ReactCompositeComponent 😓😓

import ReactCompositeComponent from 'react/lib/ReactCompositeComponent';
const _mountComponent = ReactCompositeComponent.Mixin.mountComponent;
ReactCompositeComponent.Mixin =  {abc: 111}; // it will throw some error , but doesn't work..
