Node express request queue length

Is there a way to find the web request queue length when a lot of requests hit an express server route at the same time?

I can use the listener stats from Unix but I'm looking for a more native way to do it.

This is achieved very easily. Somewhere in your program, you create a HTTP server like this:

const server = http.createServer(app);

All you need is to track incoming connections and count how many of them are open concurrently. I suppose you to store that number in app.connectionsN field

app.connectionsN = 0;

const server = http.createServer(app);

server.on('connection', function(socket) {
  // Increase connections count on newly estabilished connection
  app.connectionsN ++;

  socket.on('close', function() {
    // Decrease connections count on closing the connection
    app.connectionsN --;
  });
});
