webpack 4 禁用 uglifyjs-webpack-plugin

Question

过去 2 天我遇到了个问题。所以我决定从 webpack 构建过程中完全禁用 uglifyjs-webpack-plugin。我在 webpack 4 上找不到任何东西。

Answer 1

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

Answer 2

如果您正在管理单个 webpack.config.js 并根据环境使用 package.json npmscripts。您也可以使用这种方法。

您可以这样做：创建一个 defaultplugins 数组并检查环境，如果环境是 prod，则推送到数组，否则使用 defaultplugins。如示例所示：

package.json

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

webpack.config.js 只添加了相关部分，以便于阅读

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"],
    },
  };
};
