Is there a something like vue's mode and appear props of transition?

[mblandr]

Vue has props in transtition
mode - https://vuejs.org/guide/built-ins/transition#transition-modes
appear - https://vuejs.org/guide/built-ins/transition#transition-on-appear
are there analogs for svele?
As I see, svelte always use 'default', so removed and added DOM elements both exists while playing transition and always plays on mount

Svelte does not have these.

You can coordinate transitions to some degree by switching from transition: to separate in: & out: transitions and setting delays.

Something like appear can be build by having an #if block with a variable that is set to true in onMount/an $effect.
