[Vuejs]-Nuxt & Firebase – IE 11 (Object doesn't support property or method 'values')

Firebase has its own polyfill package included in the sdk.

You need to import that package by:

1. Creating /plugins/polyfills.js containing:

import '@firebase/polyfill';

You can, instead, import in that file the polyfills you think you need individually, so the final bundle will be smaller. Example:

import '@firebase/polyfill/node_modules/core-js/features/object/values';

2. Add to your nuxt.config.js:

plugins: [
  { src: '~plugins/polyfills', mode: 'client' },
],
