[es-dev-server] stale files after git checkout

I have started using es-dev-server to work on a large project (1000+ modules) and I really like the fact that it sets proper cache headers. This feature dropped the development loading time from 10s to 1.5s (I was using polymer serve).

Unfortunately, I ran into a problem: the server sends stale responses after switching branches. This is the scenario:

1. checkout master
2. start es-dev-server
3. edit a file
4. confirm that latest version is served
5. checkout feature branch
6. confirm that feature branch code is served
7. edit the same file
8. notice that the feature branch version is still served, instead of the edited code

if 8 did not happen, then checkout master again and notice that the code from 7. is still served.

This staleness does not go away until I restart the server, no matter how many times I edit and save the file.

This is not a browser cache problem, as I have tested this with disabled cache (via network panel).

My hunch is that it’s somehow related to the filesystem change event, but I have yet to look in the es-dev-server internals.

P.S. Thank you for this awesome project! ❤️

I have tried to replicate the issue, but it does not seem to happen anymore. The load time was not affected by this change. Thank you very much for resolving this! 🥂
