In the “How SSR Works In React 15” section you do “res.write(renderToString(<MyPage/>));” and then on the client side you do render(<MyPage/>, document.getElementById(“content”));. So technically you need both MyPage on the server and client side? How is this server side rendering when you are renderingToString on the server and then hydrating the same component on the client? I am new to this concept so I am not sure if I asked a valid question. Please give input if possible.
