Caching Gtag events on server

[RomanSkrypnik]

As we know it's not possible to obtain window object on server side
So, is that possible to cache all fired events on server and append them to dataLayer when client side is rendered?
For example: useState - if we use useState on server side, its last assigned value will be saved on client side also
If it's not possible, could you please describe why?

That's right, Gtag.js itself can't be used on the server. The composables provided by this module are SSR-safe. Meaning that they won't have an effect server-side but will trigger and event in the client. Collecting events and appending them after hydration doesn't make sense to me, because e.g. useTrackEvent will only have an effect in the client, not on the server:

// This will have no effect on the server, but track the event
// in the client after Nuxt hydration
useTrackEvent('login')
