dragjs has been designed to make it easy to create JavaScript based drag interactions. This includes use cases such as draggable panels and different types of sliders. The idea is that you use the logic from this package to build your own components as it captures concerns such as mouse and touch handling.

Demonstrations

<div id="value"></div>

Simple draggable

<div id="draggableParent"> <div id="draggable">Drag me!</div> </div> 
import { draggable } from "dragjs";

const draggableElement = document.getElementById("draggable");

draggableElement && draggable({ element: draggableElement });

Draggable with a specific handle

<div id="draggableParent"> <div id="draggabletwo"> <div>Header</div> <div>Body</div> </div> </div> 
import { draggable } from "dragjs";

const element = document.getElementById("draggabletwo");
const handle = element.children[0];

element && handle && draggable({ element, handle });

1D slider

<div id="onedContainer"></div> 
import { slider } from "dragjs";

const onedContainer = document.getElementById("onedContainer");

onedContainer && slider({
  parent: onedContainer,
  "class": "oned",
  cbs: {
    begin: () => {
      log("2dslider: begin");
    },
    change: ({ x, pointer }) => {
      const newX = clamp(x * 100, 0, 100).toFixed(2) + "%";

      console.log("2dslider: " + newX);

      if (pointer) {
        pointer.style.left = newX;
      }
    },
    end: () => {
      log("2dslider: end");
    },
  },
});

2D slider

<div id="twodContainer"></div> 
import { xyslider } from "dragjs";

const twodContainer = document.getElementById("twodContainer");

twodContainer && xyslider({
  parent: twodContainer,
  "class": "twod",
  cbs: {
    change: ({ x, y, pointer }) => {
      const newX = clamp(x * 100, 0, 100).toFixed(2) + "%";
      const newY = clamp(y * 100, 0, 100).toFixed(2) + "%";

      console.log("x: " + newX + ", y: " + newY);

      if (pointer) {
        pointer.style.left = newX;
        pointer.style.top = newY;
      }
    },
  },
});
