Advice for data-fetching for canonical urls (other locales slug)

[wiesson]

I have a Nextjs frontend and I'd like to add canonical URLs based on a pages collection. I use GraphQL to fetch the data and I'm looking for a way to get the other slug field of the other languages.

Does anyone know an easier solution than using aliases for each locale? My initial idea was like this:

  Hotels(locale: en, where: { slug: { equals: "${slug}" } }) { docs: { ... } } // current page is en, so I fetch the others as well
  deHotels: Hotels(locale: de, where: { slug: { equals: "${slug}" } }) { docs: { slug } }
  frHotels: Hotels(locale: fr, where: { slug: { equals: "${slug}" } }) { docs: { slug } }
  ...
}

This doesn't work, because the current slug doesn't match the slug in the other languages.

In the best case, I simply select the slug field of all locales when fetching the current locales document.
