🔗 The Problem of Reconnects in Phoenix LiveView

Phoenix LiveView relies heavily on stable connections, making it vulnerable to disconnections caused by things like Wi-Fi hiccups or switching tabs. When the WebSocket drops, all assigns tied to that session disappear because they exist in volatile memory. To tackle this, I learned about strategies like using Phoenix.LiveView.JS for UI state and form auto-recovery for input retention.

The introduction of LiveStash offers a persistent solution by allowing assigns to be stored either in the browser or on the server. The browser memory option is especially useful, surviving server redeploys by storing state directly in JavaScript variables. While LiveStash isn't a catch-all, it bridges the gap for complex UI states, refining how Phoenix apps manage temporary states during interruptions.
