      path: outputPath,
      chunkFilename: '[name].js',

    externals: undefined,

      ...serverConfig.resolve,
      modules: [
        path.join(__dirname, '..', 'server'),
        path.join(__dirname, '..', 'node_modules'),
        path.join(process.cwd(), 'src'),
        path.join(process.cwd(), 'node_modules'),
