Demos in project are failing

Downloading the code, npm install is successful but npm start generates an error npm ERR! missing script: start. Looking in package.json at scripts listed, there is "standard" but npm run standard just generates an error. Any idea how to fix this?

Thanks,
Rob

Start with package.json and reproduce the reported commands after npm install: npm start and npm run standard. Determine why the project demos do not run with the available scripts; done means the demos start successfully without the reported npm errors.
