Pretty cool library! Shame that the events can only be detected in Safari (for Force Touch at least).
I can't even get it to work in Safari… :/
Worked for me? What's your device and version of Safari?
Disagree with this though:
..so you can plan for the users experince if they don't support it.
This shouldn't be something that you build a whole experience/feature around.
I strongly suspect it's just poor wording. What they no doubt really mean to say is that you can provide a reliable fallbacks in the even that Force Touch or 3D Touch aren't supported. :)
