And you shouldn't be doing that iteration in an else block anyway, as the listening socket could be receiving new inbound clients at the same time that established clients are also receiving data. Bulk update symbol size units from mm to map units in rule-based symbology. But, since many things that servers do are I/O related (read from a database, get data from a file, get data from another server, etc) and node.js uses event-driven asynchronous I/O, it can often have many balls in the air at the same time so it appears to be working on lots of requests at once.

From my log file, we can see this: And at the same time of disconnect message, front-end also noticed a disconnect event which saying transport close. If you preorder a special airline meal (e.g. If you have to use middleware, I'd instead have the client send a custom "I am alive" message in a regular interval. Since front-end's saved socket is not changed, it used the old socket id when made http request. Click on "Network and Internet". One problem that becomes apparent quickly is that the socket has no explicit way of detecting when a client disconnects. Hi @jethrogb It also save the socket. If a disconnect listener is bound on a socket from middleware, the callback is not fired if the socket disconnects before the middleware completes. don't use clients.at() in your loop, it is just wasted overhead.

I have using the socket client on React Native app, when I called socketIOClient.disconnect() this disconnects from the server but when I connect to the socket again the previous events were connected again, and the below code works for me by removing all existing events and disconnecting socket conneciton. Currently the console gets spammed with the std::cout of the else case on a disconnect. Thanks! Trouble is that the network is unreliable at times and thus the server will drop my connection from time to time. the Engine.IO handshake (contains the session ID here, the Socket.IO handshake request (contains the value of the, the Socket.IO handshake response (contains the, the first HTTP long-polling request, which is closed once the WebSocket connection is established, this ID is regenerated after each reconnection (for example when the WebSocket connection is severed, or when the user refreshes the page), two different browser tabs will have two different IDs, there is no message queue stored for a given ID on the server (i.e. Linear regulator thermal information missing in datasheet.
