well you need to send a buck update that in database there are no more values:

globally, approach two: push and pull

pull - you every n seconds sending to the backend request, they say give me values from the database and update every time a sign
push through WebSocket's or SSE notification and receive updates from the backend (we need buck to implement notifications)
And here is how to update a sign that the page was not reloaded - seamus.Skiles commented on March 23rd 20 at 19:19
both options do not restart the website
or ajax for pul-approach (easier to do, but if it is critical to update ASAP, not the best option)
ws and sse also does not reload the page - garnett commented on March 23rd 20 at 19:22
