Hello,
Thanks for the SSR example, I followed the example, the differences from the SSR example vs mine are:

1. instead of using webpack-dev-middle for express, I'm using webpack-dev-server
2. instead of starting webpack-dev-server from Nodejs API, I'm running webpack-dev-server from command line for hapi, and added the writeToDisk option to devServer.

Now on server side when it calls

  const nodeExtractor = new ChunkExtractor({ statsFile: webStats });
  const { default: App } = nodeExtractor.requireEntrypoint(); 

which tries to require server side entry file - dist/js/node/main.bundle.dev.js, I'm getting error on window is not defined:

"error":"self is not defined","errorStack":"ReferenceError: self is not defined\n    at Object.<anonymous> (webpack:///(webpack)-dev-server/client:217:1)\n    at Object.../../node_modules/webpack-dev-server/client/index.js?http://localhost:2992

The error seems to come from webpack-dev-server referencing self: https://github.com/webpack/webpack-dev-server/blob/2f7f05276e10a2ce408e0903982b8bbe07699182/client-src/default/index.js#L46

Tried as suggest here - markdalgleish/static-site-generator-webpack-plugin#130 with

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

or

output: {
  // ...
  globalObject: `typeof self !== 'undefined' ? self : this`
}

even disabling HMR, none works.

Any idea how to resolve this? Appreciate your help!

Thanks

How did you solve it?

This did the trick for me:

output: {
  // ...
  globalObject: `typeof self !== 'undefined' ? self : this`
}

What's the magic behind globalObject?

I am receiving the error ReferenceError [Error]: self is not defined and webpack's stacktrace points me to the line of var chunkLoadingGlobal = self["webpackChunk_wireapp_cryptobox"]. When I am using globalObject: "this", then webpack creates var chunkLoadingGlobal = this["webpackChunk_wireapp_cryptobox"] but throws TypeError [Error]: Cannot read property 'webpackChunk_wireapp_cryptobox' of undefined. 😥
