| # Installation | ||
|
|
||
| ## From CDN | ||
|
|
||
| Install from a content-delivery network (CDN) like in the above example. | ||
|
|
||
| From cdnjs: | ||
|
|
||
| ```html | ||
| <script src="https://cdnjs.cloudflare.com/ajax/libs/tween.js/20.0.0/tween.umd.js"></script> | ||
| ``` | ||
|
|
||
| Or from unpkg.com: | ||
|
|
||
| ```html | ||
| <script src="https://unpkg.com/@tweenjs/tween.js@^20.0.0/dist/tween.umd.js"></script> | ||
| ``` | ||
|
|
||
| Note that unpkg.com supports a semver version in the URL, where the `^` in the URL tells unpkg to give you the latest version 20.x.x. | ||
|
|
||
| ## Build and include in your project with script tag | ||
|
|
||
| Currently npm is required to build the project. | ||
|
|
||
| ```bash | ||
| git clone https://github.com/tweenjs/tween.js | ||
| cd tween.js | ||
| npm install | ||
| npm run build | ||
| ``` | ||
|
|
||
| This will create some builds in the `dist` directory. There are currently two different builds of the library: | ||
|
|
||
| - UMD : `tween.umd.js` | ||
| - ES6 Module : `tween.es.js` | ||
|
|
||
| You are now able to copy tween.umd.js into your project, then include it with | ||
| a script tag, which will add TWEEN to the global scope, | ||
|
|
||
| ```html | ||
| <script src="path/to/tween.umd.js"></script> | ||
| ``` | ||
|
|
||
| or import TWEEN as a JavaScript module, | ||
|
|
||
| ```html | ||
| <script type="module"> | ||
| import * as TWEEN from 'path/to/tween.es.js' | ||
| </script> | ||
| ``` | ||
|
|
||
| where `path/to` is replaced with the location where you placed the file. | ||
|
|
||
| ## With `npm install` and `import` from `node_modules` | ||
|
|
||
| You can add tween.js as an npm dependency: | ||
|
|
||
| ```bash | ||
| npm install @tweenjs/tween.js | ||
| ``` | ||
|
|
||
| ### With a build tool | ||
|
|
||
| If you are using [Node.js](https://nodejs.org/), [Parcel](https://parceljs.org/), [Webpack](https://webpack.js.org/), [Rollup](https://rollupjs.org/), [Vite](https://vitejs.dev/), or another build tool, then you can now use the following to include tween.js: | ||
|
|
||
| ```javascript | ||
| import * as TWEEN from '@tweenjs/tween.js' | ||
| ``` | ||
|
|
||
| ### Without a build tool | ||
|
|
||
| You can import from `node_modules` if you serve node_modules as part of your website, using an `importmap` script tag. First, assuming `node_modules` is at the root of your website, you can write an import map: | ||
|
|
||
| ```html | ||
| <script type="importmap"> | ||
| { | ||
| "imports": { | ||
| "@tweenjs/tween.js": "./node_modules/@tweenjs/tween.js/dist/tween.esm.js" | ||
| } | ||
| } | ||
| </script> | ||
| ``` | ||
|
|
||
| Now in any of your module scripts you can import it by its package name: | ||
|
|
||
| ```javascript | ||
| import * as TWEEN from '@tweenjs/tween.js' | ||
| ``` | ||
|
|
||
| # Features | ||
|
|
||
| - Does one thing and one thing only: tween properties | ||
| - Does one thing only and does it well: tweens properties of an object | ||
| - Doesn't take care of CSS units (e.g. appending `px`) | ||
| - Doesn't interpolate colors | ||
| - Easing functions are reusable outside of Tween | ||
| - Can also use custom easing functions | ||

| # Installation | ||
|
|
||
| The recommended method is to use `import` syntax. Here we've listed various | ||
| install methods starting roughly with the most recommended first and least | ||
| desirable last. Evaluate all of the following methods to pick what is most | ||
| suitable for your project. | ||
|
|
||
| ## With `npm install` and `import` from `node_modules` | ||
|
|
||
| You can add tween.js as an npm dependency: | ||
|
|
||
| ```bash | ||
| npm install @tweenjs/tween.js | ||
| ``` | ||
|
|
||
| ### Without a build tool | ||
|
|
||
| #### Installed locally | ||
|
|
||
| You can import from `node_modules` if you serve `node_modules` as part of your | ||
| website, using a standard `importmap` script tag. First, assuming `node_modules` | ||
| is at the root of your website, you can write an import map like so in your HTML | ||
| file: | ||
|
|
||
| ```html | ||
| <script type="importmap"> | ||
| { | ||
| "imports": { | ||
| "@tweenjs/tween.js": "/node_modules/@tweenjs/tween.js/dist/tween.esm.js" | ||
| } | ||
| } | ||
| </script> | ||
| ``` | ||
|
|
||
| Now in any of your module scripts you can import Tween.js by its package name: | ||
|
|
||
| ```html | ||
| <script type="module"> | ||
| import {Tween} from '@tweenjs/tween.js' | ||
| </script> | ||
| ``` | ||
|
|
||
| #### Import from CDN | ||
|
|
||
| Note that, without the `importmap`, you can import directly from a CDN as with the first example above, like so: | ||
|
|
||
| ```html | ||
| <script type="module"> | ||
| import {Tween} from 'https://unpkg.com/browse/@tweenjs/[email protected]/dist/tween.esm.js' | ||
| </script> | ||
| ``` | ||
|
|
||
| You can also link your `importmap` to the CDN instead of a local `node_modules` folder, if you prefer that: | ||
|
|
||
| ```html | ||
| <script type="importmap"> | ||
| { | ||
| "imports": { | ||
| "@tweenjs/tween.js": "https://unpkg.com/browse/@tweenjs/[email protected]/dist/tween.esm.js" | ||
| } | ||
| } | ||
| </script> | ||
|
|
||
| <script type="module"> | ||
| import {Tween} from '@tweenjs/tween.js' | ||
| </script> | ||
| ``` | ||
|
|
||
| ### With a build tool | ||
|
|
||
| If you are using [Node.js](https://nodejs.org/), | ||
| [Parcel](https://parceljs.org/), [Webpack](https://webpack.js.org/), | ||
| [Rollup](https://rollupjs.org/), [Vite](https://vitejs.dev/), or another build | ||
| tool, then you can install `@tweenjs/tween.js` with `npm install | ||
| @tweenjs/tween.js`, and `import` the library into your JavaScript (or | ||
| TypeScript) file, and the build tool will know how to find the source code from | ||
| `node_modules` without needing to create an `importmap` script: | ||
|
|
||
| ```javascript | ||
| import * as TWEEN from '@tweenjs/tween.js' | ||
| ``` | ||
|
|
||
| However, note that this approach requires always running a build tool for your | ||
| app to work, while the `importmap` approach will simply work without any build | ||
| tools as a simple static HTML site. | ||
|
|
||
| ## Manual build | ||
|
|
||
| Another approach is to download the source code with git, manually build the | ||
| library, then place the output in your project. Node.js is required for this. | ||
|
|
||
| ```bash | ||
| git clone https://github.com/tweenjs/tween.js | ||
| cd tween.js | ||
| npm install | ||
| npm run build | ||
| ``` | ||
|
|
||
| This will create some builds in the `dist` directory. There are currently two different builds of the library: | ||
|
|
||
| - ES6 Module in `/dist/tween.esm.js` (recommended) | ||
| - UMD in `/dist/tween.umd.js` (deprecated, will be removed in a future major version) | ||
|
|
||
| You are now able to copy one of those two files into your project, and use like this (recommended): | ||
|
|
||
| ```html | ||
| <script type="module"> | ||
| import {Tween} from 'path/to/tween.esm.js' | ||
| </script> | ||
| ``` | ||
|
|
||
| or (deprecated, to be removed in future major): | ||
|
|
||
| ```html | ||
| <script src="path/to/tween.umd.js"></script> | ||
| <script> | ||
| const {Tween} = TWEEN | ||
| </script> | ||
| ``` | ||
|
|
||
| where `path/to` is replaced with the location where you placed the file. | ||
|
|
||
| > [!Note] | ||
| > You can also download these files from unpkg, for example here: | ||
| > https://unpkg.com/browse/@tweenjs/[email protected]/dist/ | ||
| ## Global variable from CDN (deprecated) | ||
|
|
||
| > [!Note] | ||
| > This method is deprecated and will be removed in a future major version! | ||
| Install a global `TWEEN` variable from a content-delivery network (CDN) using the UMD file. | ||
|
|
||
| From cdnjs: | ||
|
|
||
| ```html | ||
| <script src="https://cdnjs.cloudflare.com/ajax/libs/tween.js/23.1.3/tween.umd.js"></script> | ||
| ``` | ||
|
|
||
| Or from unpkg.com: | ||
|
|
||
| ```html | ||
| <script src="https://unpkg.com/@tweenjs/tween.js@^23.1.3/dist/tween.umd.js"></script> | ||
| ``` | ||
|
|
||
| Then use the `TWEEN` variable in any script: | ||
|
|
||
| ```html | ||
| <script> | ||
| const {Tween, Easing, Group /*, ...*/} = TWEEN | ||
| const tween = new Tween(someObject) | ||
| // ... | ||
| </script> | ||
| ``` | ||
|
|
||
| > [!Note] | ||
| > unpkg.com supports a semver version in the URL, where the `^` in the | ||
| > URL tells unpkg to give you the latest version 20.x.x. | ||
| ## CommonJS (deprecated) | ||
|
|
||
| Skip this section if you don't know what CommonJS is! | ||
|
|
||
| > [!Note] | ||
| > This method is deprecated and will be removed in a future major version! | ||
| Any of the above methods work in older systems that still use CommonJS. Repeat | ||
| any of the above methods but using `dist/tween.cjs` instead of | ||
| `dist/tween.esm.js` or `dist/tween.umd.js`. | ||
