Error when adding firebase Auth

[educkf]

I tried to "merge" this example with your other example using Firebase Auth, but I keep getting the error:

The XMLHttpRequest compatibility library was not found.

This error happens on server render, only when I import Auth to the vuex store.
Any idea on how to solve it?
thanks!

I also have the same isssue with nuxt universal config. When i use express instead of nuxt as default server am able to solve this by adding the XMLHttpRequest compatibility module to the server/index.js

global.XMLHttpRequest = require('xmlhttprequest').XMLHttpRequest

but using nuxt as default the same problem appear
