First of all, thank you so much for putting this course together, I'm loving getting more out of node and express with it!

Halfway through though, I began to have an SyntaxError: Unexpected token message when booting up the server, without any more information on where it was. Turns out this isn't a syntax error in the code per se, and it's bound to happen to most Mac users at some point, so I thought I'd share the problem and how to fix it:

That damned .DS_Store file in the OSX filesystem.

In the / route, we're grabbing all files from that folder, not just the JSON ones. If it encounters something that is not a JSON file, this will of course break since it can't be parsed. .DS_Store, being invisible in the file system, will only show up on the logs for the list of all files.

A solution would be to filter all files and narrow them down to only the JSON ones.
Happy expressing!
