title: What's the alternative to ComponentDidMount in React Server Rendered Application?
body: <p>I have created an isomorphic React application. Everything works fine till I was trying to put some animations on my elements. If it was a client-side rendering app, I would do that by writing the animation function and invoke the function in componentDidMount() component lifecycle method. But unfortunately, this method won't work for SSR. </p>
  
  <p>How to invoke my animation function in this case? (tried componentWillMount already, it's not working)</p>
