I am learning about Nuxt 3 at the moment and currently focus on things that I knew how to handle in Nuxt 2 and for which I did not yet find a (similar, simple) solution in Nuxt 3.
One of those things are anonymous middlewares. How can I build those in Nuxt 3 / what is the closest thing in Nuxt 3 that can be used to get the same functionallity? Do I really have to call an API endpoint? This seems so overkill compared to Nuxt 2.
This discussion may be helpful to track the status of the question.
The latest and most useful place where you can get the up-to date info is here.
TLDR: no client-side middleware as of today but you can have workarounds.
