It's a toy app obviously, but I was impressed with the potential of so many technologies being integrated with each other (It even has Svelte in the mix via LiveSvelte[1]).
Agreed! I am hopeful that future versions might help address these challenges at the framework level. It’s the Achilles heel to LiveView. As soon as the connection gets unreliable or has some latency a lot of the magic goes away. Most of the time the productivity boost from working in LiveView more than makes up for it, though.
