I dont like the routes locale thing either. I'm basing my locale off of the value in the cookie NEXT_LOCALE, and if that's not present then the value in the 'accept-language' header, and if that's not present then my default locale.

Mhm, makes sense. So there's no automated way to do it?

There might be but I haven't found it

Okay, thanks for your answer! Do you get those value i.e. in getServersideProps? What's your experience with what these values are when you haven't visited / yet?

I get them in the middleware. But you can get them anywhere you have access to the request object, and the cookies (which is nearly everywhere from what I can tell)

You can visit any path on the website and they will be accessible

i think you can get user locale from Accept-Language header. i remember i made it before inside middleware nextjs appdir project.
