@aofl/polyfill-service
Advanced tools
Implements a customized version of @webcomponents/webcomponentsjs/webcomponents-loader.js that uses dynamic imports to load polyfills. It also allows for lazy loading other polyfills based on a config file.
npm i -S @aofl/polyfill-service
// sample-config.js
export default {
'Object.assign': () => import('@aofl/polyfill-service/src/object-assign-polyfill'),
'fetch': () => import('isomorphic-fetch'),
'Reflect': () => import('harmony-reflect'),
'Array.prototype.find': () => import('array.prototype.find'),
'html-imports': {
test() {
return !('import' in document.createElement('link'));
},
load: () => import('@webcomponents/webcomponentsjs/webcomponents-bundle')
}
};
// init-polyfill-service.js
import {Polyfill} from '@aofl/polyfill-service';
import polyfills from './sample-config';
const ready = Polyfill.loadAll(polyfills); // promise
export default ready;
polyfill.loadAll() returns a promise. In addition to this WebComponentsReady is fired once all promises are loaded.
If using webpack you will have to use imports-loader to fix the global variable in webcomponents polyfills.
// webpack.config.js
...
module: {
rules: [
{
test: /@webcomponents/,
loader: 'imports-loader?this=>window'
},
]
}
