Event handlers became properties in Svelte 5 e.g. s/on:stop/onstop/

[evdama]

Describe the feature

Neither bug nor feature but slider events in Svelte 5 are now written without the colon i.e. on:stop=() becomes onstop=(). See https://svelte.dev/docs/svelte/v5-migration-guide#Event-changes for more details.

so you're just requesting the Documentation be updated? :)

[evdama]

Well, not sure as this works i.e. the function is being executed

on:stop={event => updateWaveForm(event)}

whereas this doesn't

onstop={event => updateWaveForm(event)}

I'll have a look at the source then... maybe something obvious I'm missing 🤷

ahhh, ok, I think it's because the code is still technically written in Svelte4, but you can import it with Svelte5 as it's backwards compatible.

Just to clarify.

We are supposed to still use on:click instead of onclick.

Meaning we are depending on the backwards compatibility grace period of Svelte 5.

I do not think I have a proper suggestion on how to handle this, but the current situation appears to be a little brittle.

I ended up at this issue, because I did a global search and replace for on:click -> onclick and the slider "broke".

Migrating back to on:click got it to work, but no idea for how long!

It should be multiple years, I would hope

Maybe I'll do a v5 in svelte5 after I've gotten the docs updated and v4 released
