webpack 4 disable uglifyjs-webpack-plugin

I have had this problem for the last 2 days. So I decided to completely disable uglifyjs-webpack-plugin from webpack build process. I was not able to find anything on webpack 4.

If you are managing single webpack.config.js and using package.json npmscripts based on environment. You can use this approach as well.

You can do something like this: creating a defaultplugins array and check the environment, if environment is prod, the push to array otherwise use defaultplugins. as shown in example:

package.json

"config-prod": "webpack --env.NODE_ENV=prod --parallel build-webpack",
"build-prod": "npm run config-prod"

webpack.config.js Added only relevant sections, so that it's easy to read

var webpack = require("webpack");
var path = require("path");
const UglifyJSPlugin = require("uglifyjs-webpack-plugin");
const HtmlWebpackPlugin = require("html-webpack-plugin");
const MiniCssExtractPlugin = require("mini-css-extract-plugin");
const webpackUtilities = require("./webpack.utilities");

module.exports = (env) => {
  var defaultplugins = [
    new webpack.DefinePlugin({
       ///// section deleted
    }),
    new MiniCssExtractPlugin({
      ///// section deleted
    }),
  ];

  return {
    mode: env.NODE_ENV == "prod" ? "production" : "development",
    devtool: env.NODE_ENV == "prod" ? "" : "source-map";,
    entry: {
      ///// section deleted
    },
    output: {
         ///// section deleted
    },
    module: {
      rules: [
        {
          ///// section deleted
        },
      ],
    },
    plugins:
      env.NODE_ENV == "prod"
        ? [...defaultplugins, new UglifyJSPlugin()]
        : [...defaultplugins],
    resolve: {
      extensions: [".js", ".jsx", ".scss", ".css"],
    },
  };
};

module.exports = {
    optimization:{
        minimize: false, // <---- disables uglify.
        // minimizer: [new UglifyJsPlugin()] if you want to customize it.
    }
}
