can't install web app

I realize it's 16 months old - did you abandon this example? 

installing web app is causing errors. 

This no longer exists:
"node-pre-gyp WARN Tried to download(404): https://fsevents-binaries.s3-us-west-2.amazonaws.com/v1.2.4/fse-v1.2.4-node-v79-darwin-x64.tar.gz"

LMK if you want to work on fleshing out a more complete graphql example. Maybe I can help.
