mapd-crossfilter stopped working after upgrading to babel7 and webpack4

:beetle: 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?
