Thanks for the information, next time I have a problem I will check the issues first. Soory not to get back to you sooner but when I set the
"NPM_CONFIG_PRODUCTION" environment variable to "false" I came up with a timeout problem (I am dragonmaths) and didn't want to reply and say all is well and neither did I want to mention the problem here as I had found out about using issues on github and so wanted to use that.
Anyway all my issues so far you have resolved and I appreciate both the boilerplate you have contributed and the help you have given to me and others .
I expect I will come across new problems as I further learn about multi-user sites and heroku.
Once again thank you for your help
