Svelte 5 Compatability

[evaneliasyoung]

When attempting to use the use:tooltip action or <Tooltip content={{component: ...}}>...</Tooltip> in the Svelte 5 Release Candidate ([email protected]) I encounter this error.
I understand that Svelte 5 has not officially released, however support for the next generation would be a nice addition.

errors.js:86  Uncaught Svelte error: component_api_invalid_new
Attempted to instantiate node_modules/@svelte-plugins/tooltips/dist/action-tooltip.svelte with `new Action_tooltip`, which is no longer valid in Svelte 5. If this component is not under your control, set the `compatibility.componentApi` compiler option to `4` to keep it working.

Now that 5 is out, this would be awesome

[stalkerg]

seems like this

/// svelte.config.js
export default {
	compilerOptions: {
		compatibility: {
			componentApi: 4
		}
	}
};

should help, but it's not working for me.

I would love a svelte 5 version too. Cant get compatibility.componentApi to work.

Agree, moving to Svelte5 might be the better option. Question is, how straightforward is it? There seem to be some internal APIs in use,...so some redesign might be requried.
