PolyfillServicePlugin

This is a webpack plugin that detects required polyfills using autopolyfiller and loads them from Polyfill service.

Installation

npm install polyfill-service-webpack

and then add the PolyfillServicePlugin to the webpack config:

var PolyfillServicePlugin = require("polyfill-service-webpack");
var webpackConfig = {
    plugins: [
        new PolyfillServicePlugin({
            minify: true,
            callback: "onPolyfillsLoaded",
            defaultFeatures: {
                "Object.assing": ["always"],
            },
            flags: [],
            libVersion: ">0.0.0",
            unknown: "polyfill",
        }),
    ],
};

After that, you can invoke the special function __load_polyfills__ from your JS:

// request the polyfills
var polyfillsLoaded = __load_polyfills__();
 
polyfillsLoaded(function () {
    // do something when the polyfills have loaded
});
