mapd-crossfilter stopped working after upgrading to babel7 and webpack4

🪲 bug

• Operating System and version: OS X 10.14.4
• Browser and version: Chrome 73 on macOS (Mojave)
• Steps to reproduce (including dashboard link): Upgraded React application configuration by using newer version of babel7 and webpack4
• Description of issue: mapd-crossfilter is failing with the following issue-

TypeError: Cannot set property 'resultCache' of undefined 
(function (exports) {
  crossfilter.version = "1.3.11";
  exports.resultCache = resultCache;
...

This is my babel configuration -

"babel": {
    "plugins": [
      "add-module-exports",
      "@babel/plugin-syntax-dynamic-import",
      [
        "@babel/plugin-proposal-decorators",
        {
          "legacy": true
        }
      ],
      [
        "@babel/plugin-proposal-class-properties",
        {
          "loose": false
        }
      ]
    ],
    "presets": [
      [
        "@babel/preset-env",
        {
          "modules": false
        }
      ],
      [
        "react-app",
        {
          "helpers": false,
          "absoluteRuntime": false
        }
      ]
    ]

  }

And this is my webpack configuration -

Did you ever find a way to get around this issue? I am running into the same thing

[sandipp]

@paradom Yeah, I did hacky fix changing into the library exports function.

I am not really sure what you mean, would it be possible to show me what you changed?
