Webpack TerserPlugin - exclude node module

Question

Using a custom Angular Builder, I'm trying to exclude an entire module from minification/optimization.

The Webpack .md file says

exclude
Type: String|RegExp|Array Default: undefined

Files to exclude.

Can I use this setting to exclude an entire directory (which is the node module)?

---

The current code is

export default class CustomizeTerserBrowserBuilder extends BrowserBuilder {
  public buildWebpackConfig(root: any, projectRoot: any, host: any, options: any): any {
    const webpackConfig = super.buildWebpackConfig(root, projectRoot, host, options);

    if (
      webpackConfig.optimization &&
      webpackConfig.optimization.minimizer &&
      Array.isArray(webpackConfig.optimization.minimizer)
    ) {
      const terserPlugin = (webpackConfig.optimization.minimizer as any[]).find(
        minimizer => minimizer instanceof TerserPlugin
      );

      if (terserPlugin) {
        terserPlugin.options.exclude = [/node_modules/];
      }
    }

    return webpackConfig;
  }
}

Maybe you are looking for this

   module.exports = {
      optimization: {
        minimizer: [
          new TerserPlugin({
            exclude: /node_modules/,
          }),
        ],
      },
    };
