The LV will die on disconnect, you can probably pubsub to something to see the event or write a hande_info() callback and try to save some kind of recovery data to the server then but it is probably preferable to encode your recovery data into the browser and either use:
phx-auto-recoverand a form Form bindings — Phoenix LiveView v1.2.5 or- browser session/cookie/localstorage: Saving and Restoring LiveView State · The Phoenix Files
- Or sometimes you can just encode the recovery data into the URL and
handle_params()depending on what you are working with (you could encode some recovery token and load progress from the db for example).
In any case, careful that you sanitise the data coming back. Your form will be easily editable, the session can be made more tamper resistant. You also don’t have to encode “user_id=1” into the form, you could encode the data similarly to how Fly talks about using the session.
