  1. Great tutorial!! could you plz tell us why the app isn’t working on IE after production build while everything works just fine on dev mode?

  2. How to configure webpack if I want to import a react-native module (not node_module) into reactjs. Both of them being siblings in a mono repo?

  3. It’s great that you’re providing us with beautiful webpack, however, there are a few deprecated plugins in this webpack configuration, such as uglifyjs-webpack-plugin, optimize-css-assets-webpack-plugin, and react lazy loading. However we can use css-minimizer-webpack-plugin ,terser-webpack-plugin instead of optimize-css-assets-webpack-plugin and uglifyjs-webpack-plugin. And React-Loadable is not necessary as it comes with react itself

  4. Great tutorial. I did have a couple of issues, and it probably was because I’ve never setup webpack for myself.
    The first issue was until I had configuration info in webpack.development I kept getting this error “TypeError: require(…) is not a function” when running npm run dev. My second issue was getting the error about not being able to process the app.scss file until I added
    module.exports = () => ({
    module: {
    rules: [
    test: /\.scss$/,
    use: [
    “css-loader”, //
    “sass-loader”, //

    to the webpack dev file. Both issues got resolved at the same time since I was playing around with the first on and stumbled on the second one.
