Why is there no lifecycle event for componenDidUpdate?

[agenthunt]

Is there any specific reason, there is no lifecycle event for componenDidUpdate? I have a usecase where I need to find something in the dom after the component has updated ? Any suggestions on how to go about this ?

We do really need a lifecycle event for componentDidMount. However, it might not be that necessary to have a lifecycle event for componentDidUpdate. Because:

1. You can hook up events in componentDidUpdate for such use cases
2. There is no componentDidUpdate hook in virtual-dom

Having said that, we still need a lifecycle event for componentDidMount. And it's probably fine having other lifecycle events such as componentDidUpdate as well. I am going to make updates. The API is going to look like this:

const Foo = component('Foo', function (interactions) {
  const componentDidUpdate$ = interactions.get('React_componentDidUpdate')
    .map(refs => {
      const inputElement = React.findDOMNode(refs.refInput);
      // manipulate DOM elements
    });

  return Rx.Observable.just('')
    .merge(componentDidUpdate$)
    .map(value => <input type="text" ref="refInput" />);
}):

Sorry it took me a long time to look back at this issue. We have now supported the component's lifecycles by introducing a new parameter for the component's definition function. Details can be found at Working with React

I'm now closing this issue. Feel free to reopen this if you have any questions. Thanks.
