Hmmm, strange. I am unable to reproduce. demand-express most certainly imports hammerjs. In main.ts:

import 'hammerjs';

Did you make any local changes?

@clbond I did a little digging since we were running into some similar issues. I wasn't able to reproduce in the demand-express example but I was able to reproduce in the cli example as well as another barebones cli project with angular-ssr. Just attach a swipe event to an element and it'll throw this error

Did you import hammerjs? There's no reason it shouldn't work

Make sure you are using import 'hammerjs';
and not using import { hammerjs } from "path to hammer js";

Make sure you are using import 'hammerjs';
and not using import { hammerjs } from "path to hammer js";

Unless you use custom baseUrl and path. Then you will have to use import '../node_modules/hammerjs';
