[Here our plugins list](https://www.npmjs.com/browse/keyword/es6-tween)\n\n## Demos\n\n- Demo #1 [Morphing SVG Shape + Cross-browser SVG Transform](https://codepen.io/dalisoft/pen/mMJmxX)\n- Demo #2 [Morphing SVG Shape](https://codepen.io/dalisoft/pen/BdLydv)\n- Collection on the [Codepen](https://codepen.io/collection/DapBmv/)\n\n## Installation\n\nDownload the [library](https://unpkg.com/es6-tween/bundled/Tween.js) and include it in your code:\n\n```html\n\n```\n\n### CDN-Hosted version\n\n- See [cdnjs-hosted version](https://cdnjs.com/libraries/es6-tween) for get which result you want\n- NOTE: `@latest` suffix sometimes saves life by loading latest, because sometimes CDN services will not load the latest\n\n- Now you can load from CDN\n\n```html\n\n\n\n\n\n\n\n\n```\n\n### More advanced users might want to\n\n#### Using `import`\n\n```javascript\nimport { Easing, Tween, autoPlay } from 'es6-tween';\n```\n\n#### Using [getlibs](https://github.com/activewidgets/getlibs)\n\n```html\n\n\n```\n\n#### Using `npm` or `yarn`\n\n```bash\n$ yarn add es6-tween\n# or\n$ npm install es6-tween\n```\n\nThen include the Tween.js module with the standard node.js `require`:\n\n```javascript\nconst { Tween, Easing, autoPlay } = require('es6-tween');\n```\n\nAnd you can use Tween.js as in all other examples--for example:\n\n```javascript\nconst t = new Tween(/* etc */);\nt.start();\n```\n\nYou can run script commands to build modules into single `UMD` compatible file:\n\n#### Using commands\n\n```bash\n$ yarn build # builds production files\n# or\n$ yarn dev # builds and watchs development files\n```\n\nThen reference the library source:\n\n```html\n\n```\n\n## Features\n\n- Tweens everything you give them, string, number, number of arrays, number of object, all-to, interpolators and much more. Endless possibilites\n- Can use CSS units (e.g. appending `px`)\n- Can interpolate colours\n- Easing functions are reusable outside of Tween\n- Can also use custom easing functions\n- Much of easings\n\n## Compatiblity Testing\n\nThanks to BrowserStack for providing us testing in a real devices to make it cross-browser, bug-free and better.\nBrowserStack saved my countless hours, before i spent on testing much of time, now it's very easy. I recommend to others use this service.\nI sure, BrowserStack helps us to make it, so i am linking to BrowserStack as our sponsor.\n[](https://www.browserstack.com/)\n\n## Tests\n\n```bash\nyarn test\n```\n\nor you can go [here](https://travis-ci.org/tweenjs/es6-tween) for more information, tests and etc...\n\nevery time you want to run the tests.\n\nIf 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.

For example, boxShadow has values like \"10px 10px 20px 30px rgb(255,0,0)\" which would utterly confuse other plugins. This method allows us to split that data apart and grab only the numeric data and attach it to uniquely-named properties of a generic proxy object ({}) so that we can feed that to virtually any plugin to have the numbers tweened. However, we must also keep track of which properties from the proxy go with which CSSPropTween values and instances. So we create a linked list of MiniPropTweens. Each one records a target (the original CSSPropTween), property (like \"s\" or \"xn1\" or \"xn2\") that we're tweening and the unique property name that was used for the proxy (like \"boxShadow_xn1\" and \"boxShadow_xn2\") and whether or not they need to be rounded. That way, in the _setPluginRatio() method we can simply copy the values over from the proxy to the CSSPropTween instance(s). Then, when the main CSSPlugin setRatio() method runs and applies the CSSPropTween values accordingly, they're updated nicely. So the external plugin tweens the numbers, _setPluginRatio() copies them over, and setRatio() acts normally, applying css-specific values to the element.\n\t\t\t * This method returns an object that has the following properties:\n\t\t\t * - proxy: a generic object containing the starting values for all the properties that will be tweened by the external plugin.

These instances store important information like the target, property, starting value, amount of change, etc. They can also optionally have a number of \"extra\" strings and numeric values named xs1, xn1, xs2, xn2, xs3, xn3, etc. where \"s\" indicates string and \"n\" indicates number. These can be pieced together in a complex-value tween (type:1) that has alternating types of data like a string, number, string, number, etc. For example, boxShadow could be \"5px 5px 8px rgb(102, 102, 51)\". In that value, there are 6 numbers that may need to tween and then pieced back together into a string again with spaces, suffixes, etc. xs0 is special in that it stores the suffix for standard (type:0) tweens, -OR- the first string (prefix) in a complex-value (type:1) CSSPropTween -OR- it can be the non-tweening value in a type:-1 CSSPropTween. We do this to conserve memory.\n\t\t\t * CSSPropTweens have the following optional properties as well (not defined through the constructor):\n\t\t\t * - l: Length in terms of the number of extra properties that the CSSPropTween has (default: 0). For example, for a boxShadow we may need to tween 5 numbers in which case l would be 5; Keep in mind that the start/end values for the first number that's tweened are always stored in the s and c properties to conserve memory. All additional values thereafter are stored in xn1, xn2, etc.\n\t\t\t * - xfirst: The first instance of any sub-CSSPropTweens that are tweening properties of this instance. For example, we may split up a boxShadow tween so that there's a main CSSPropTween of type:1 that has various xs* and xn* values associated with the h-shadow, v-shadow, blur, color, etc. Then we spawn a CSSPropTween for each of those that has a higher priority and runs BEFORE the main CSSPropTween so that the values are all set by the time it needs to re-assemble them. The xfirst gives us an easy way to identify the first one in that chain which typically ends at the main one (because they're all prepende to the linked list)\n\t\t\t * - plugin: The TweenPlugin instance that will handle the tweening of any complex values. For example, sometimes we don't want to use normal subtweens (like xfirst refers to) to tween the values - we might want ThrowPropsPlugin or BezierPlugin some other plugin to do the actual tweening, so we create a plugin instance and store a reference here. We need this reference so that if we get a request to round values or disable a tween, we can pass along that request.\n\t\t\t * - data: Arbitrary data that needs to be stored with the CSSPropTween. Typically if we're going to have a plugin handle the tweening of a complex-value tween, we create a generic object that stores the END values that we're tweening to and the CSSPropTween's xs1, xs2, etc. have the starting values. We store that object as data. That way, we can simply pass that object to the plugin and use the CSSPropTween as the target.\n\t\t\t * - setRatio: Only used for type:2 tweens that require custom functionality. In this case, we call the CSSPropTween's setRatio() method and pass the ratio each time the tween updates. This isn't quite as efficient as doing things directly in the CSSPlugin's setRatio() method, but it's very convenient and flexible.\n\t\t\t * @param {!Object} t Target object whose property will be tweened. Often a DOM element, but not always. It could be anything.\n\t\t\t * @param {string} p Property to tween (name). For example, to tween element.width, p would be \"width\".\n\t\t\t * @param {number} s Starting numeric value\n\t\t\t * @param {number} c Change in numeric value over the course of the entire tween. For example, if element.width starts at 5 and should end at 100, c would be 95.\n\t\t\t * @param {CSSPropTween=} next The next CSSPropTween in the linked list. If one is defined, we will define its _prev as the new instance, and the new instance's _next will be pointed at it.\n\t\t\t * @param {number=} type The type of CSSPropTween where -1 = a non-tweening value, 0 = a standard simple tween, 1 = a complex value (like one that has multiple numbers in a comma- or space-delimited string like border:\"1px solid red\"), and 2 = one that uses a custom setRatio function that does all of the work of applying the values on each update.\n\t\t\t * @param {string=} n Name of the property that should be used for overwriting purposes which is typically the same as p but not always. For example, we may need to create a subtween for the 2nd part of a \"clip:rect(...)\" tween in which case \"p\" might be xs1 but \"n\" is still \"clip\"\n\t\t\t * @param {boolean=} r If true, the value(s) should be rounded\n\t\t\t * @param {number=} pr Priority in the linked list order.
