Yep, definitely a job for pinia. But a second fetch doesn’t seem unreasonable as well. The “list page” fetches an API endpoint to get a basic list of users, the “detail page” fetches another API endpoint returning a single user with the detailed information. If you are worried if you are doing to much requests, you also may have a look on Nuxt. With the SSR functionality it will save you multiple requests made.
We’ll why do you want this? If you want (in this context) “invisible” data shared with different components use a store or a composable. If you want parameters in your url that have an effect on the content that is displayed, use the router params. Mixing both requirements would let to 1. User enters URL with name and ID 2. A piece of code rewrites the url, memorizes the name and removes that info from the url. That’s a SEO nightmare.
I guess the problem is a perspective problem: that’s no pollution, that’s a clear description of what the user will see. Also the user could copy the url, send it to a colleague and this colleague would see a different page if you want to “cleanup” the url.
I have a TrueNAS Scale NAS in my home network. Since they using k3s, your NVidia GPU should be picked up automatically: https://docs.k3s.io/advanced#nvidia-container-runtime-support If you have troubles, I guess a little tweak here and there and you should be fine. I generally recommend Truenas, it serves me several years until now.
