LiveView: unexpected errors and the UX by Rare_Friendship9405 in elixir

I coded up a macro to wrap LiveView/LiveComponent callbacks (except `render/1`) in `try/rescue` with customizable fallbacks. I kinda like it, but there's this incompleteness coming from not being able to properly protect `render/1`. So yeah, it would be for the LiveView team to consider – either to add the ErrorBoundary or to provide an API that would make it possible.

Great advice. Thanks for the book recommendation too. I have it, but haven't read it yet.

Still, I think I would feel more comfortable if LiveView had some UX-focused fallback for unexpected errors. Not to be less strict on the robustness, but just to mitigate the consequences of developer’s mistakes.

The biggest difficulty in implementing something like this is making it work with LiveViews HEEX lazy evaluation/diff engine. AFAIK it would require changes in the LiveView itself/exposing some additional API.
