Just curious why you preferred SvelteKit to Nuxt? Literally every single thing you said of SvelteKit is also true of Nuxt.
I like them both, but tend to lean more toward Nuxt for the modules ecosystem and layers/extends. I also find composing reusable props with typescript to be nicer in Nuxt, but that's more of a Vue vs Svelte thing than Nuxt vs SvelteKit.
This description of Nuxt 3 couldn't be further from reality. Performance is on par with anything else I've tried (SvelteKit, Remix, Next) and the DX (module ecosystem, layers, auto imports, vite, etc ) are actually what's made it my default.
I tried to switch to firefox a few months ago, but it had no way to view websocket frames in the dev tools. This was kind of a deal breaker for me at the time as I was doing a lot of ws work. Have they remedied this?
It's just even less obvious to me why I might pick it over Vue at this point.
