Moveable JavaScript library is a JavaScript library that makes an element draggable, resizable, scalable, scrollable, rotatable, roundable, clippable, and wrappable.

Moveable js Implementation

Install and import the moveable.

# NPM
$ npm install moveable --save
import Moveable from "moveable";

Or load the umd version from the dist folder


<-- or from a cdn -->

Initialize the Moveable library and specify the target element

const moveable = new Moveable(document.body, {

// check whether an event has been attached to a component.
moveable.hasOn(eventName);
// indicate whether the event is attached. 
moveable.hitTest(el);
// indicate whether the event is attached. 
moveable.hitTest(el);
// update the shape of the moveable
moveable.updateRect();
// change options or properties
moveable.setState(state, callbackopt);
// triggers a custom event
moveable.trigger(eventName, customEventopt, ...restParam);
// Instantly Request (requestStart - request - requestEnd)
moveable.request("draggable", { deltaX: 10, deltaY: 10, isInstant: true });
// Start move
const requester = moveable.request("draggable");
requester.request({ deltaX: 10, deltaY: 10 });
