feat(chat): gate realtime websocket to authenticated users and disconnect on unmount by trtajim · Pull Request #413 · hscstack/platform

trtajim · 2026-10-11T04:48:18Z

Summary

Exported disconnectEcho() in echo.ts to cleanly terminate active Pusher WebSocket connections and reset the singleton instance.
Gated setupRealtime() in Chat/Index.vue so guest visitors do not establish Pusher WebSocket connections, preserving connection quota.
Added a realtime notice banner for unauthenticated visitors in Chat/Index.vue.
Added disconnectEcho() in Chat/Index.vue's onUnmounted lifecycle hook to immediately free the connection slot when navigating away from chat.
Added a watch(currentUser) handler to dynamically connect or tear down WebSockets upon auth state changes.

Summary by CodeRabbit

New Features
- Guests now see a notice above the chat message stream when they are not signed in.
Improvements
- Realtime chat messages and presence are active only while signed in. Signing out disconnects realtime activity, and signing in sets it up again.
- Realtime connections are also disconnected when leaving the chat page.

📝 Walkthrough

Walkthrough

The chat page now gates realtime subscriptions on authentication, disconnects Echo when the user logs out or the page unmounts, and displays a guest notice when no user is authenticated.

Changes

Chat realtime authentication lifecycle

Layer / File(s)	Summary
Echo disconnection `resources/js/lib/echo.ts`	Adds `disconnectEcho()` to disconnect Echo when present, clear the cached instance, and remove `window.Echo` when available.
Authentication-gated chat realtime `resources/js/pages/Chat/Index.vue`	Sets up realtime subscriptions when a user is authenticated. On logout, leaves chat and presence channels and disconnects Echo. Disconnects Echo on teardown and displays a guest notice when no user is authenticated. Also reorders icon imports.

Estimated code review effort: 2 (Simple) | ~10 minutes

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Reconnect when the authenticated user changes.

If currentUser changes directly from user A to user B, neither watcher branch runs. The cached Echo connection and presence subscription remain associated with user A. Compare user IDs, then leave and disconnect before setting up user B’s subscriptions.

Do not create an Echo instance during cleanup.

After the cache is empty, getEcho() creates an instance when a Pusher key exists. The logout path can therefore start a connection just to leave and disconnect it. The unmount path has the same sequence at Line 1528. Use a non-creating lookup for both cleanup paths, or let disconnectEcho() handle an absent instance.
