We already know what is tweening and why it's need, so there no need to describe it's, Google will do this if you want. This library is not made as alternative to another libraries, it's has own pros and cons


TWEEN.autoPlay(true); // simplify the your code
let coords = { x: 0, y: 0 };
let tween = new TWEEN.Tween(coords)
  .to({ x: 100, y: 100 }, 1000)
  .on('update', ({ x, y }) => {
    console.log(`The values is x: ${x} and y: ${y}`);


Starting at v3, we provide excluded plugins from core, so our core becomes lighter and faster. Here our plugins list



Download the library and include it in your code:

<script src="bundled/Tween.js"></script>

CDN-Hosted version

  • See cdnjs-hosted version for get which result you want

  • NOTE: @latest suffix sometimes saves life by loading latest, because sometimes CDN services will not load the latest

  • Now you can load from CDN

<!-- jsDelivr -->
<script src=""></script>
<!-- unpkg -->
<script src=""></script>
<!-- npmcdn -->
<script src=""></script>

Using import

import { Easing, Tween, autoPlay } from 'es6-tween';

Using getlibs

<script src=""></script>
<script type="x-module">
  // ES6
  import { Easing, Tween, autoPlay } from 'es6-tween'
  // CommonJS
  const { Tween, Easing, autoPlay } = require('es6-tween')

Using npm or yarn

$ yarn add es6-tween
# or 
$ npm install es6-tween

Then include the Tween.js module with the standard node.js require:

const { Tween, Easing, autoPlay } = require('es6-tween');

And you can use Tween.js as in all other examples--for example:

const t = new Tween(/* etc */);

You can run script commands to build modules into single UMD compatible file:

Using commands

$ yarn build # builds production files 
# or 
$ yarn dev # builds and watchs development files 

Then reference the library source:

<script src="bundled/Tween.min.js"></script>


  • Tweens everything you give them, string, number, number of arrays, number of object, all-to, interpolators and much more. Endless possibilites
  • Can use CSS units (e.g. appending px)
  • Can interpolate colours
  • Easing functions are reusable outside of Tween
  • Can also use custom easing functions
  • Much of easings

Compatiblity Testing

Thanks to BrowserStack for providing us testing in a real devices to make it cross-browser, bug-free and better. BrowserStack saved my countless hours, before i spent on testing much of time, now it's very easy. I recommend to others use this service. I sure, BrowserStack helps us to make it, so i am linking to BrowserStack as our sponsor. Browser Stack Logo


$ yarn test

or you can go here for more information, tests and etc...

every time you want to run the tests.

If you want to add any feature or change existing features, you must run the tests to make sure you didn't break anything else. If you send a PR to add something new and it doesn't have tests, or the tests don't pass, the PR won't be accepted. See contributing for more information.


Thanks to

these tools developers and to their community and without these tools maybe this library wouldn't be possible
