> You'd have the same problem if you were storing all your state in memory for any web application regardless of your library choice.
But that's the thing - traditional server-side web applications don't do this. The the stateless request/response cycle of traditional server-rendered apps is a _huge_ advantage from a system design standpoint. State is bad. State is hard to manage correctly over time. Elixir makes it possible to manage this in-memory state relationship better than other languages, but it's still difficult to do at scale regardless.
LiveView turns stateless web applications into stateful web applications, and this is a problem most folks aren't considering when they see developer experience improvements the LiveView project claims. This is _the_ specific tradeoff that LiveView makes, and I wish folks wouldn't handwave it away as if it were trivial to manage. It's not. It's a fundamentally different client/server architecture.
Source/disclaimer: I work at a large company with a large LiveView deployment, we have spent a ton of time and money on it, and it's a pain in the ass. I still love Elixir, I just think LiveView is oversold.
I guess my quibble is that I’ve talked to Jose and Chris about this and I don’t think they’re overselling it. The caveats are in the docs and they expect you to understand the tools.
And realistically there are cases where I’d use another tool.
