Subscribing in componentWillMount() versus React's documentation about react-redux-realworld-example-app HOT 2 OPEN

^ Should be done in cDM

cDM = componentDidMount()
cWM = componentWillMount()

When you add fetching or any other type of mutation in cWM, you are inherently re-rendering your component. cWM and ES6 class constructors actually do the same thing, in this context. (Not always in other context's but for this example and in React, they are effectively the same). Also has a performance drawback because for every mutation in cWM, the component renders twice instead of once.

Moral of the story, mutations should always go in cDMs. You should do your best to initialize state in the constructor. I actually rarely use cWM.

This is a valid issue and should probably at least have someone take a look at.
