Javascript touch movement, track when user swipes from edges

Question

I need to track user touch events. I want to track when user swipes from edges.
For example when user swipes from left vertical edge I will show a menu, from right edge

Answer 1

I had trouble making this work using Hammer.JS - v2.0.8 and refering to the actual documentation.
Based on 2BitNerd's answer here is what I used:

Hammer(document.body).on("swiperight", function(e) {
    var endPoint = e.pointers[0].pageX;
    var distance = e.distance;
    var origin = endPoint - distance;
    if (origin <= 15) {
        // They swiped, starting from no more than 15px away from the edge. 
    }
});

The .gesture attribute has to be skipped for me to make this work as it does not exist.
