 If you have a more advanced project and use [Vagrant](https://www.vagrantup.com/) to run your development environment in a Virtual Machine, you'll often want to also run webpack in the VM.

 `--watch-poll` makes sure that webpack can detect changes in your files. By default webpack listens to events triggered by the filesystem, but VirtualBox has many problems with this.

+## Conclusion
+
+We made the Vagrant box accessible from a static IP, and then made webpack-dev-server publicly accessible so it is reachable from a browser. We then tackled a common problem that VirtualBox doesn't send out filesystem events, causing the server to not reload on file changes.
