Error: 'window is not defined' with Webpack 4

I’m posting this issue for reference more than anything else, in case others are searching for a fix. The temporary fix is at the end, perhaps it’s worth adding that to the README?

---

When using this plugin with a fresh install of Webpack 4 (4.6.0 in my test) I get the following error:

ERROR in ReferenceError: window is not defined

Having dug into it further, it appears it is a side effect of this issue where the umd target generates invalid code for running inside a Node.js context.

The temporary fix is detailed here, where you can add the following to your Webpack config to change the global keyword from window to this:

output: {
  // ...
  globalObject: "this"
}
