setup Google Analytics 4 in nuxt.js

Question

I'm having issues setting up a new Google Analytics 4 (GA4) account with Nuxt. Everything seems configured ok based on tutorials, however my traffic doesn't show up in GA (dev & production)

In nuxt.config.js I have the following

  buildModules: [
    '@nuxtjs/tailwindcss','@nuxtjs/google-analytics'
  ],
  googleAnalytics: {
    id: 'G-HWW3B1GM6W'
  },

The google id is a GA4 Data Stream id with my production website. I tried 2 different streams, with www and without, but the traffic doesn't show up in GA4.

Solution

[UPDATE]

If you want to use GA4 Property (which is what has the ids in the format G-XXXXXXXXXX) you can try to use vue-gtag package by creating a plugin:

import Vue from 'vue'
import VueGtag from 'vue-gtag'

Vue.use(VueGtag, {
  config: { id: 'G-XXXXXXXXXX' }
})

Add this in nuxtconfig.js

plugins: ['@/plugins/gtag']

About the problem indicated in your message, that plugin you mentioned works with the Universal version of Google Analytics (which is what has the ids in the format UA-XXXXXXXXX-X), like the example in your link:

 buildModules: [
   '@nuxtjs/tailwindcss','@nuxtjs/google-analytics'
 ],
 googleAnalytics: {
   id: 'UA-XXXXXXXX-X'
 },

The code you entered in the example, G-HWW3B1GM6W, refers to the new Google Analytics 4 which, being a different system from the previous one and does not work (yet) with that plugin.

So I suggest you to create a Universal Analytics type Property and use its ID (UA-XXXXX-X) with the plugin you indicated. You can find it by clicking on Show advanced options (when you create a new property):
