Getting out of LiveView on disconnected render
There is a LiveView page with live route to it. All works fine. Now, during the “disconnected” phase, I would like to make a decision whether to continue with connected phase or bail out early to – for example – DeadView 404 handler. I know I could probably add a plug and pass that route through a dedicated pipeline, but since it’s a specific, isolated case, I am not too eager to go that path. Any other methods come to your head, maybe? Maybe a method to get hold of the initial conn somehow?

Stoping with an error from within a LV is done by raising an exception, which can be handled by Plug.Exception.

If you raise an error in mount/3 or the initial handle_params/3 of the static render it can be handled by the plug pipeline and never reach a place where the js client is booted up. So there are options before it‘s to late and indeed http becomes no longer the layer to error on.
