Chapter 7 UI alert

[mathewgrabau]

I know there is an older issue regarding Chapter 7 (still open and demonstrating the same error that I was having).

I discovered first that web3 needed to be updated to 1.2.2 (works around a v8 and node-gyp error), but the alert is still appearing about failing to connect. The specific error is that callbackify is missing.

I used the chapter10+11 project as described in the book. Sidenote: it appears that project is based on yarn - should the instructions be to use yarn instead of npm? I am getting several warnings about the mix.

Thank you for the tip.
At end of chapter 7, running npm install web3 before npm install addressed the particular problem of installing the npm dependencies.

@mathewgrabau Thank you for opening this issue. I will try to get some time to dedicate to updating the book and repo in the next few weeks.
