🚀 Feature Proposal

This plugin currently supports Next 12 and 13. While working on upgrading dependencies for fastify's v5 release, we noticed that upgrading Next to 14 breaks tests, specifically in regard to the use of the basePath configuration option.

We decided to leave that behind as out of scope for the v5 upgrade, but it would be good to extend compatibility to Next 14 as well at some point.

Should we drop/archive this module?

Perhaps, it has around 700 weekly downloads, not sure if you'd define that as used or not much used https://www.npmjs.com/package/@fastify/nextjs

Anyhow, this needs a volunteer to take this on.
