// Full API
// mix.js(src, output);
// mix.react(src, output); <-- Identical to mix.js(), but registers React Babel compilation.
// mix.preact(src, output); <-- Identical to mix.js(), but registers Preact compilation.
// mix.coffee(src, output); <-- Identical to mix.js(), but registers CoffeeScript compilation.
// mix.ts(src, output); <-- TypeScript support. Requires tsconfig.json to exist in the same folder as webpack.mix.js
// mix.extract(vendorLibs);
// mix.sass(src, output);
// mix.standaloneSass('src', output); <-- Faster, but isolated from Webpack.
// mix.fastSass('src', output); <-- Alias for mix.standaloneSass().
// mix.less(src, output);
// mix.stylus(src, output);
// mix.postCss(src, output, [require('postcss-some-plugin')()]);
// mix.browserSync('my-site.test');
// mix.combine(files, destination);
// mix.babel(files, destination); <-- Identical to mix.combine(), but also includes Babel compilation.
// mix.copy(from, to);
// mix.copyDirectory(fromDir, toDir);
// mix.minify(file);
// mix.sourceMaps(); // Enable sourcemaps
// mix.version(); // Enable versioning.
// mix.disableNotifications();
// mix.setPublicPath('path/to/public');
// mix.setResourceRoot('prefix/for/resource/locators');
// mix.autoload({}); <-- Will be passed to Webpack's ProvidePlugin.
// mix.webpackConfig({}); <-- Override webpack.config.js, without editing the file directly.
// mix.babelConfig({}); <-- Merge extra Babel configuration (plugins, etc.) with Mix's default.
// mix.then(function () {}) <-- Will be triggered each time Webpack finishes building.
// mix.extend(name, handler) <-- Extend Mix's API with your own components.
// mix.options({
//   extractVueStyles: false, // Extract .vue component styling to file, rather than inline.
