How can I get LiveView to tell morphdom to move a whole sub-tree to a different parent in the dom?

Instead you are relying on the fact that you only perform a stream_insert() call if something has changed, and you are telling LiveView to re-send that particular stream item.

I’ll eventually know the acts too, but as a high-level take-away from all you’ve said about streams it sounded like you concluded that when you use streams it nullifies the optmisations from Jose’s article. It would be really awesome if he can post an update to that article that outlines how / if / where any or all of that changes when using streams.

@garrison

Just be careful to make sure you fully understand how LiveView diffs those nodes. I recommend spending some time looking at the diffs sent over the websocket in your browser dev tools if you haven’t already, and experimenting with ways to shrink them (LiveComponents, streams, etc).

I’m definitely tryingmy damnest to do get to understand exactly that. “This is the Way” to quote the Mandelorian(s). For me that is a lifestyle.

As I’ve said many times, if you have a very tight (constrained) use case this is tractable. If you have a very complex UI, it’s not. Only you can make that call, I’ve simply tried to give some perspective.

Yes, that is a call I need to make, and soon too. But having only one option really isn’t an option at all. (It’s like having the option to go skydiving without a parachute - it might technically be possible, but if you intend to survive and go again, you don’t really have the option) I merely hoping to arrive at decision-making time with at least two actual choices so I can choose the one that best fit the whole jizsaw puzzle.

This is a digression, but it’s funny because I remember Google going to great lengths to deal with this exact problem in one of the Zanzibar papers. They had some elaborate caching scheme - I don’t remember exactly how it worked.

It’s an even greater diversion, but I choose to stay as far away from Google as humanly possible, which in reality isn’t very far, such is their influence, and I try not to make it anyone else’s problem that I feel that way.
