Optimise for using course remotely

[jrd656]

Hey, I've been trying to follow this workshop but am visiting family and don't have the luxury of a mentor/study-buddy. I think that this workshop could be much improved for independent learning by including what the server.js file contains at the end of the 5th and 6th Stages.

I've got to Stage 5/6 but I can't make sense of what's going on as I don't think my code matches what the workshop is doing at the moment.
