Describe the bug

The vue docs says : If you also want to apply a transition on the initial render of a node, you can add the appear prop.
https://vuejs.org/guide/built-ins/transition.html#transition-on-appear

There is no transition on the initial render with nuxt, it however works when unmounting/remouting the node afterwards.

Working fine on vanilla vue : https://codesandbox.io/p/sandbox/jovial-kapitsa-qvhxzt

I think this is a Vue SSR issue - see if you can reproduce without Nuxt with https://stackblitz.com/github/nuxt-contrib/vue3-ssr-starter

[danielroe]

Confirmed - see https://stackblitz.com/edit/github-85wcaq?file=src/App.vue. We can track upstream in vuejs/core#6951.

@danielroe I still see this issue.
Is there a reason for not planning to resolve it?
Just to understand.

A fairly workaround is to add the same animation at "onMounted" but it's not working at the same mode and we loose the beforeEnter hook.

Thank you so much.

[danielroe]

It's not that we don't want to resolve it, but it is a Vue bug and there is an upstream issue tracking it.

[danielroe]

Oh, I see it is already meant to be resolved. If you are still encountering it please raise a new issue

[liqueflies]

You mean on nuxt repo or vue repo?
I've updated the nuxt dependecy to it's latest version from the demo above:
https://codesandbox.io/p/devbox/nuxt3-appear-4pzthr

Issue still present, if you prefer open a new issue, I'll do that but i think it's the same

[danielroe]

Can you reproduce it with Vue without Nuxt?

[liqueflies]

Can you reproduce it with Vue without Nuxt?

If this is the vue-ssr template that I found on nuxt, yes, the problem is the same:

https://stackblitz.com/edit/github-jer1rm

Is this again related to vue?

[danielroe]

Yes, if it reproducible there then it should be raised upstream at vuejs/core

[liqueflies]

Yes, if it reproducible there then it should be raised upstream at vuejs/core

Opened the issue into the vuejs/core repository.

Thank you so much.

EDIT: Trying into vue play is working correctly
