Ionic 4 prevent shorten the class names for prod build

I am building an ionic 4 app and using class names references in the local offline pouch DB it works fine. But when I make the Prod build with optimization true it shortens the classes to single alphabet name -

e extends i.a { constructor(){super(),this.isActive=!0 }}

I have used custom-webpack for keeping the class name with the following code -

module.exports = cfg => {
    const options = cfg.optimization.minimizer[cfg.optimization.minimizer.length - 1].options.terserOptions;
    if (options) {
        options.keep_classnames = true;
    }
    return cfg;
};

It works fine for ionic serve --configration prod

but not for ionic build --configuration prod

I want to keep class names for ionic build --configration prod with optimization:true.

Please help thanks.

You can specify the TerserWebpackPlugin to keep the class names.

module.exports = {
  optimization: {
    minimize: true,
    minimizer: [
      new TerserPlugin({
        terserOptions: {
          keep_classnames: true,
          keep_fnames: true,
        },
      }),
    ],
  },
};
