Problem with Hot Reloading

First of all, Thank you!! I have been looking for a boilerplate which includes React, SASS and webpack2 with most updated version and config. I had trouble setting up on my own, mainly on SASS compilers and also hot reloading.
I had cloned your repository and did
```
npm install
node server.js
```
The modules compiled successfully, but when I make some changes to App.js and save it, these changes are not being reflected on the browser even after I reload the browser. could you please help me with this problem?

Reproduce the problem with `npm install` and `node server.js`, then edit and save `App.js` and reload the browser. Inspect the webpack and hot-reloading setup used by `server.js` to identify why the change is not reflected. Done means edits to `App.js` appear in the browser after saving and reloading.
