Reduce support cases: npm dependencies

Quite a few support cases where the user forgot to install all npm dependencies, leading to errors like "Cannot find module". The fix was to redeploy after installing or updating dependencies

Another potential problem is where the user doesn't commit a package-lock.json to their repo and/or `npm ci` and automatically gets their deps updated on every deployment.
