In order for you and your team to never rely on transient local state (either in the cloud or your own computer), we "start from scratch".

However, our process of starting from scratch is actually faster than running `npm install` on your own computer in many cases.

As an example, I've found myself getting into the habit of using `now` instead of `localhost`.

This doesn't address the poster's issue: If you reinstall every time, the results won't always be the same (not that I personally hold this as a big issue, I'd consider it on the programmer to freeze their package.json)
