window is not defined

[hronro]

I got this error when I upgrade webpack to v4

[hronro]

It seems like this is caused by webpack hot reload: webpack/webpack#6642

Should be fixed in Webpack soon.

For now I've made workerize-loader detect when output.globalObject is set to window, and it will simply show a warning and recommend setting it to self or this.

What should I do if I am using create-react-app without ejecting (I don't have access to the config file of Webpack)? Just upgraded to react-script 2.0+, it starts to break.

@bidiu - can you file an issue with create-react-app? They should be using self as the default.

@developit Thanks!

You can use react-app-rewired with config.output.globalObject= self in the config-overrides in a CRA to change this
