Laravel Mix Polyfill

A Laravel Mix extension for Babel Polyfill.

Usage

First, install the extension.

npm install laravel-mix-polyfill --save-dev

or

yarn add laravel-mix-polyfill --dev

Then, require it within your webpack.mix.js file:

let mix = require('laravel-mix');

require('laravel-mix-polyfill');

mix.js('resources/js/app.js', 'public/js')
   .sass('resources/sass/app.scss', 'public/css')
   .polyfill({
      enabled: true,
      useBuiltIns: "usage",
      targets: {"firefox": "50", "ie": 11}
   });

Options

Name	Type	Default	Description
enabled	boolean	true	Should polyfill be used.
useBuiltIns	string	"usage"	See here and here for detailed description.
targets	string, object, boolean	"defaults"	Allows a target (browser) environment to be specified. This can either be: • a browserslist-compatible query ("> 0.25%, not dead"), • an object of minimum environment versions to support ({"chrome": "58", "ie": "11"}), • or false to transform all ECMAScript 2015+ code by default. • Setting to false will also allow use of browserslist config sources (like .browserslistrc). See here and here for more information. You can test string values on browserl.ist.
corejs	number	2	The version of core-js to be used.
debug	boolean	false	Outputs the targets/plugins used to the console.
