At least it works now :D. But I find it quite difficult to change the thinking from just using JS to get my functionallity to using methods provided by nuxt and vue.
So that is interesting. I was trying to use this custom component for the link, so that the styling only effects specific links, but that did not work. When using just NuxtLink itself and styling the default classes it works fine.
The classes are properly set on the a tag for Installed, but there are no classes set at the a tag for Modules. But if i go to just /modules, it is setting the classes for the a Tag with modules perfectly fine.
