Draggy

Make any element draggable. Demo.

import Draggable from 'draggy';

//make an element draggable
var el = document.querySelector('.my-element');
var draggy = new Draggable(el, {
	release: true,
	sniper: false,
	axis: 'x'
});

//bind event handler
draggy.on('drag', function () {
	// ...
});

Options

Parameter	Default	Description
`axis`	`null`	Restrict movement by axis: `'x'`, `'y'` or `null`.
`pin`	`[0,0, selfWidth, selfHeight]`	Defines a smaller area within the draggable element that stays within movement limits. Useful to restrict movement based on an inner shape rather than the full element.
`precision`	`1`	Round position to that extent, in pixels.
`css3`	`true`	Use `position` vs `translate3d` to place element. The first is more precise and reliable, the second is faster.
`release`	`false`	Continue movement when user releases drag.
`repeat`	`false`	Loop movement by one of axis: `'x'`, `'y'` or `'both'`.
`sniper`	`true`	Slow down movement by pressing Ctrl/Cmd.
`threshold`	`0`	A movement threshold required to start drag - whether an array, number or function.
`within`	`document`	Restrict movement within the container. Pass `'parent'` to use parent node.
`handle`	`self.element`	Use element or selector as a handle for drag. Clicking outside the handle is ignored.
`cancel`	`undefined`	Ignore dragging started on the elements matching the selector.
`droppable`	`undefined`	Selector, element or list of elements to detect droppable areas. For each drop element will be invoked `drop`, `dragover` and `dragout` events.

Events

Name	Description
`dragstart`	Drag started. Called both on element/controller.
`threshold`	Entered threshold mode. Called on controller.
`drag`	Drag iteration. Called both on element/controller.
`track`	Track movement. Called on controller.
`release`	User released drag. Called on controller.
`dragend`	Drag has completely finished. Called both on element/controller.
`dragover`	Called on self and on drop target.
`dragout`	Called on self and on drop target.
`drop`	Called on self and on drop target.

What draggy is not

It doesn’t do ghost move, as it is not draggable behavior and can be implemented externally.
It doesn’t do mouse hiding on drag, as it can be done via callbacks.
It doesn’t init itself automatically - it's up to you to decide when to create/init draggable.
It doesn’t polyfill native draggable, as it targets to complete simple task of visual placement of element.
