Can you import isDevMode from @angular/core and then only log this warning if isDevMode() is true?

Rather than making it any, could you add a GestureManager interface that just copies the members of HammerManager that we're using?

Makes HammerJS and logs a warning if it's missing, instead of crashing the app.

Updated @jelbourn. I've replaced the HammerJS interfaces with our own stripped-down alternatives. |
