Real-Time Phoenix - 'wscat' not working on page 32
Hi, I wasn’t able to get wscat
working with the code presented in the book. For example, I needed to perform the following to determine what code was needed for Phoenix 1.6:
mix phx.gen.socket User
mix phx.gen.channel Ping
Are there plans to update the PDF/ePub and associated code bundle to support Phoenix 1.6?

Total apologies for the delay here.
There are no plans right now to update the book for Phoenix 1.6. Unfortunately the upgrades required (text / code changes) would likely make it a v2 book which would be up to Prag.
Luckily, the number of changes is fairly small in the end. Mostly seems related to the generators + PubSub 2.0 having a different setup. The concepts still apply and all of the functions should work as expected.
Thanks for providing your gen commands here.
