Update or replace? about svelte-portal HOT 6 CLOSED

It's not possible with current implementation, because Portal is inserted in target using appendChild.
Replace can be a bit hard because of need to destroy svelte components before replacing them to avoid memory leaks.

There is no need to destroy the component immediatly. I copied the code and added just three lines. I clean all the dom children before appendChild. It works, but does not look clean. Then component leave anyway. Any ideas?

I have situation when several portals compete for the single target, the last one wins. I have to control it. The example is modals. Opening a new modal removes the previous one

@AlgoTrader It's possible in Svelte but I guess it's not the intend of a Portal so this feature would be a little off-topic for this component.

@AlgoTrader it can lead to memory leaks if you just remove all inner elements including svelte rendered components.

As I said current implementation of svelte-portal do not allow you safely replace target's content. And I do not plan to add this feature in near future, so I will close this issue.
