Trying to extend webpack’s webpack-bundle-tracker so it doesn’t show path

I have a webpack.config.js file here. I’m trying to modify or overwrite the writeOutput method of the webpack-bundle-tracker app (saved as BundleTracker) so that when the webpack-stats-prod.json file is created it creates this (‘no path’):

{
  "status": "done",
  "assets": {
    "78d4aa4961e00276aa1fe5487f7fcae4.eot": {
      "name": "78d4aa4961e00276aa1fe5487f7fcae4.eot",
      "path": "no path"
    },

instead of this (absolute path):

{
  "status": "done",
  "assets": {
    "78d4aa4961e00276aa1fe5487f7fcae4.eot": {
      "name": "78d4aa4961e00276aa1fe5487f7fcae4.eot",
      "path": "/Users/name/static/webpack/bundles/prod/78d4aa4961e00276aa1fe5487f7fcae4.eot"
    },

I’m trying to do this by copying the webpack-bundle-tracker app into a new variable (NoPathBundleTracker) and then overwriting the writeOutput method.

So far I’m getting this error: TypeError: Class constructor BundleTrackerPlugin cannot be invoked without 'new' but I’m wondering if this is the best way to achieve my custom output.

const path = require('path');
const webpack = require('webpack');
const BundleTracker = require('webpack-bundle-tracker');

const config = require('./webpack.base.config.js');

var NoPathBundleTracker = function(options) {
  BundleTracker.call(this, options);
};

// Edit webpack-bundle-tracker to not show path
NoPathBundleTracker.prototype = Object.create(BundleTracker.prototype);
NoPathBundleTracker.prototype.writeOutput = function (compiler, contents) {
    
    var chunks = contents['chunks'];

    if (chunks) {
      for (var chunk in chunks ) {
        var chunkArray = chunks[chunk];
        var i;
    
        for (i = 0; i < chunkArray.length; ++i) {
          var chunkObject = chunkArray[i];

          for ( var chunkinfo in chunkObject ) {
            chunkObject['path'] = 'no path';
          }
        }
      }
    }

    BundleTracker.prototype.writeOutput.call(this, compiler, contents);
};

config.output.path = path.resolve('./bundles/prod');

config.plugins = config.plugins.concat([
  new NoPathBundleTracker({
    filename: './webpack-stats-prod.json'
  }),

  new webpack.DefinePlugin({
    'process.env': {
    'NODE_ENV': JSON.stringify('production')
  }}),

]);

module.exports = config;
