Auto-renewal error
89 USD The CRM system implements auto-update of data. However, the script does not automatically trigger when the data on the server is updated itself, and only starts working when I manually request data from the server. This needs to be fixed.
Frontend: JS creates an EventSource to the SSE endpoint, listens for push notifications. If SSE is unavailable, it switches to AJAX polling via fetch()/XHR at intervals.
Backend: PHP daemons (totum-gom) under systemd support long-lived SSE connections, monitor database changes, and send insert/update/delete events to clients.
Ideally, this should happen step-by-step as follows:
User opens the table → JS creates new EventSource('/stream/table/{id}').
Another user makes changes → trigger in the database → PHP daemon creates an SSE event, for example event: update, data: {...}.
Event is sent to all connected clients → JS parses evt.data → updates the DOM.
If EventSource does not work → JS makes a GET /api/table/updates?since=… after N seconds and processes the changes.
Thanks to SSE and systemd daemons, changes are reflected instantly without reloads.
I will send server access details in private message

I have experience implementing auto-refresh via SSE and fallback to AJAX. I will check the trigger logic in the database and the handling of demon connections. I will fix it so that events are sent immediately after changes, without the need for manual API calls.
