Very nice! Is it just me or does it look like the verify method doesn't wait a proper amount for the hapi server to startup? Often getting this error when verifying:

✗ Error connecting to http://localhost:33907: ECONNREFUSED

Error: connect ECONNREFUSED
    at errnoException (net.js:904:11)
    at Object.afterConnect [as oncomplete] (net.js:895:19)

It looks like the ECONNREFUSED error existed prior to upgrading to Hapi 8. #98 was opened a few days ago. I tried running the unmodified workshop with Hapi 7 and occasionally got the error as well. I'll dig around and see if I can find a fix

Just found a problem with cookies (the section, not the real ones). Seems like the validation just passes the cookie 'session=eyJrZXkiOiJtYWtlbWVoYXBpIn0=; Max-Age=0; Expires=Sat, 13 Dec 2014 19:27:21 GMT; Domain=localhost; Path=/{path*}' as it was received: https://github.com/hapijs/makemehapi/blob/7da6437aadba0dfe2636dbb881302de0621c5a31/exercises/cookies/exercise.js#L86 This is the same thing as telling the server that there is a Max-Age, Expires, etc. value in the data set. That wasn't a problem but some time in the last months the default settings for cookies where that the value has to be strict and the value for the "Expires" field doesn't match that setting.

This is no longer WIP in progress. All the exercises should with Hapi 8 now.

hey @linclark any chance you could review this so folks can start learning hapi 8?

[linclark]

[lloydbenson]

Overall looks pretty good, just a few stylist things to follow hapi standards.
