title: Auto reload react server on update
body: <p>I'm new to React. I'm having some problems with react server. After starting the server by <code>npm start</code> if I work on the source code and make some changes, I have to stop the server and restart it to make that change available on the browser. Is there anyway to make it auto compile and refresh the browser on update ? (Like <code>nodemon</code> for node ?)</p>
