Usage

import rosin from "rosin";
 
const swiper = rosin(document.body);

Emitted values are relative to the DOM node you instantiated on.

swiper.on("tap", ({ x, y }, e) => {});
swiper.on("mouseup", ({ x, y }, e) => {});
swiper.on("mousedown", ({ x, y }, e) => {});
 
/** Fired once on each swipe */
swiper.on("left", ({ x, y }, e) => {});
swiper.on("right", ({ x, y }, e) => {});
swiper.on("up", ({ x, y }, e) => {});
swiper.on("down", ({ x, y }, e) => {});

Drag events emit a different payload. It looks like this:

{
  ix, // initial X coordinate
  iy, // initial Y coordinate
  dx, // delta (change) in X coordinate
  dy, // delta (change) in Y coordinate
  x,  // current X coordinate
  y,  // current Y coordinate
}
/** Fired on every animation frame */
swiper.on("drag", (coords, e) => {});
swiper.on("dragLeft", (coords, e) => {});
swiper.on("dragRight", (coords, e) => {});
swiper.on("dragUp", (coords, e) => {});
swiper.on("dragDown", (coords, e) => {});

Each emitter also returns a function to destroy itself:

const tapListener = swiper.on("tap", () => {});
 
tapListener(); // destroy listener

To destroy the entire instance:

swiper.destroy();
