Panning and zooming events for any target. May come handy for webgl, canvas, svg, images or pure html manipulations. Handles mobile pinch-zoom, drag and scroll interactions, provides inertial movement.

See demo.

const panzoom = require('pan-zoom');

panzoom(target, e => {
		//e contains all the params related to the interaction

		//pan deltas
		e.dx;
		e.dy;

		//zoom delta
		e.dz;

		//coordinates of the center
		e.x;
		e.y;

		//type of interaction: mouse, touch, keyboard
		e.type;
	}
);
