All inclusive customElements polyfill for every browser
npm install @ungap/custom-elementsThis module provides the Custom Elements V1 API as defined by standards, including the ability to extend builtin elements, all in ~2K _minified_ and _gzipped_ / _brotlied_.
The polyfill gracefully enhances the following minimum versions of at least these browsers, up to their latest version:
* Chrome 38
* Firefox 14
* Opera 25
* Internet Explorer 11 and Edge 12
* Safari 8 and WebKit based
* Samsung Internet 3
Either install this module via npm i @ungap/custom-elements, and include it in your project, or use a CDN such as unpkg.com to obtain the _minified_ version of this module.
``html`
If targeted browsers are ES2015 compatible, the es.js file would provide the same polyfill, just lighter, as no transpilation is used.
`html`
If installed as module, please remember to include it on top of your main JS file.
`js
// ESM
import '@ungap/custom-elements';
// CJS
require('@ungap/custom-elements');
`
The module will incrementally patch the global window/self reference, adding a customElements` object that is compatible with the API.
This module simply provides @webreflection/custom-elements module under the ungap umbrella.
