I bought the code, read it and felt very sad. There is work to be done to implement typing, since describing types using “any” is tantamount to not having them at all....
In addition to the localizer, there is a message hardcode.
NextJS 13.1 with page router. Work needs to be done to migrate applications to the router.
I think this code can be used as a template for development, but as a ready-made solution it is a little crude.
