Laravel mix for dev and production

I think you can use this https://laravel.com/docs/5.7/mix#environment-variables

Like this https://github.com/JeffreyWay/laravel-mix/issues/1155#issuecomment-326623833

So use require('dotenv').config(); in webpack.mix.js file.

Yes but how should I do it in webpack.mix.js?

Should I use if ?

How should actually write this?

@MARKOTITEL - I typically do this

if (mix.inProduction()) {
    mix.version();
     //whatever else
}

Yes, thank you.

Just refreshed to post Laravel Documentation solution, which I could not notice today. So my webpack.mix looks like

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

/*

mix.js('resources/js/app.js', 'public/js')
   .sass('resources/sass/app.scss', 'public/css');

if(!mix.inProduction()) {
   mix.sourceMaps();
   mix.webpackConfig({ devtool: 'inline-source-map'})
}
