Getting window is not defined on my own project

[GonzaloCalandria]

Hello everyone! I'm trying to apply this to my own project and I'm having the following error when I try to run my node server

C:\Projects\amc-demo\development\react-app\node_modules\u2f-api-polyfill\u2f-api-polyfill.js:14
  if ('u2f' in window || !('chrome' in window)) {
               ^

ReferenceError: window is not defined

I read that I can't use window object with server side rendering but I can't find anything on the net to fix this.. so I hope you can help me.

Indeed window doesn't exist on a Node server. I remember that we used a library to manage that scenario. You may have to do the same

Thank you @pfauchere for your answer! and do you have some sample for that scenario that you mention?
