It looks like the native Nuxt auth library has changed significantly since this post was made so I would recommend you take a look at that (https://auth.nuxtjs.org). That has a convenience method on this.$auth.user. I’m going to write an update to this post using the updated standard library, so I’d love to hear how you get on.
This library has a hook for user info when completing the OAuth call back, see fetchUser here.
