        hot: true,
        port: 3000,
    },
    module: {
        rules: [
            {
                test: /\.tsx?$/,
                exclude: /node_modules/,
                use: [

                                        // swc-loader will check whether webpack mode is 'development'
                                        // and set this automatically starting from 0.1.13. You could also set it yourself.
                                        // swc won't enable fast refresh when development is false
                                        refresh: isDevelopment,
                                        // Enable the new JSX runtime module (e.g. `react/jsx-runtime`)

                                    },
