title: Wait for redux props in componentDidMount
body: <p>I want to load something from my API endpoint in <code>componentDidMount</code>, but that needs to have something else from the redux store passed into it.</p>
  
  <p>Thing is, it seem that componentDidMount gets fired before the props are populated from redux, so the jwt auth token isn't in the redux state yet, and I get a 401 error.</p>
  
  <p>How can I get the code to wait for the redux state to be loaded, then call the function, or have it loop every, lets say 500ms, until the props are identified?</p>
  
  <p>If there's some place other than <code>componentDidMount</code> I should put it I'm open to suggestions.</p>
