Ошибка: не перехвачено (в обещании) ReferenceError: реакция не определена

Я уже давно получаю эту ошибку. Изображение целиком: Я сделал компонент реакции в модуле npm и пытаюсь использовать этот модуль npm в другом проекте, который использует preact вместо react. Вышеупомянутая ошибка возникает, как только страница проекта пытается загрузиться.

Я связал свой модуль npm с помощью webpack, вот моя конфигурация webpack: 

const path = require('path');
module.exports = {
entry: "./src/components/index.js",
output: {
    filename: "main.js",
    path: path.resolve(__dirname, "dist"),
    libraryTarget: 'umd',      
    publicPath: '/dist/',      
    umdNamedDefine: true 
},
module: {
    rules: [
        {
            test: /\.css$/,
            use: ["style-loader", "css-loader"]
        },
        {
            test: /\.m?js$/,
            exclude: /(node_modules|bower_components)/,
            use: {
              loader: 'babel-loader',
              options: {
                presets: ['@babel/preset-env', '@babel/preset-react'],
                plugins: ['@babel/plugin-proposal-class-properties']
              }
            }
        },
        {
            test: /\.(woff|woff2|eot|ttf|svg)$/,
            exclude: /node_modules/,
            loader: 'url-loader',
            options: {
                publicPath: './src/fonts/',
                name: './src/fonts/[name].[ext]',
                limit: 1000
            }
        }
    ]
},
resolve: {
    alias: {
        "react" : "preact-compat",
    "react-dom" : "preact-compat"
    }
    
},
externals: {      
    // Don't bundle react or react-dom      
    react: {          
        commonjs: "react",          
        commonjs2: "react",          
        amd: "React",          
        root: "React"      
    },      
    "react-dom": {          
        commonjs: "react-dom",          
        commonjs2: "react-dom",          
        amd: "ReactDOM",          
        root: "ReactDOM"      
     }  
 }
}

Вот мой package. json: 

{
   "name": "tutorial12",
    "version": "1.0.41",
    "description": "",
    "main": "./dist/main.js",
    "scripts": {
        "test": "echo \"Error: no test specified\" && exit 1",
        "buildWebpack": "webpack --config webpack.config.js"
    },
    "author": "",
    "license": "ISC",
    "peerDependencies": {
    "react": "16.8.3",
    "react-redux": "5.0.7",
    "redux": "4.0.0",
    "redux-thunk": "2.3.0"
   },
   "devDependencies": {
       "preload-webpack-plugin": "3.0.0-beta.3",
       "webpack": "4.43.0",
       "webpack-cli": "3.3.12",
       "babel-plugin-react-transform": "3.0.0",
       "css-loader": "3.6.0",
       "file-loader": "6.0.0",
       "style-loader": "1.2.1",
       "url-loader": "4.1.0",
       "react": "16.8.3",
       "react-redux": "5.0.7",
       "redux": "4.0.0",
       "redux-thunk": "2.3.0"
    },
    "dependencies": {
       "@babel/cli": "7.10.4",
       "@babel/core": "7.10.4",
       "@babel/plugin-proposal-class-properties": "7.10.4",
       "@babel/preset-env": "7.10.4",
       "@babel/preset-react": "7.10.4",
        "babel-loader": "8.1.0"
     }
   }

То, что я пробовал:

  1. Добавление resolve: {alias: {"react": "preact-compat", "react-dom" : "preact-compat"}} в webpack.config. js
  2. Добавление a resolve: {alias: {"react": path.resolve(__dirname, "./node_modules/react"), "react-dom" : path.resolve(__dirname, "./node_modules/react-dom")}} в webpack.config. js.
  3. Добавление resolve: {alias: {"react": path.resolve(__dirname, "./node_modules/preact-compat"), "react-dom" : path.resolve(__dirname, "./node_modules/react-dom")}}
  4. Перемещение зависимостей в пакете. json из поля devDependencies в поле dependencies

Вот стек ошибки:
