Nice router

[freemvmt]

Pronounced row-ter of course ;)

Your central controllers (controllers/index.js) file is really good, I can tell immediately what's going on from reading it. Very clear!

Also nice that you've removed some functions from immediate view, as with controllers/behaviour.js.

Could be neatened up by abstracting the controllers into separate files, like you have for the client and server routes imported from the error.js file.

Then you could easily see all your routes at one glance, e.g.

router.get('/', home.get)
router.get('create-user', user.post)
router.get('presents', presents.get)
router.use(error.client);
router.use(error.server);
