Limit Socket io connections number

Is it possible to limit socket io connections number in nodejs ?

I know one can configure limit by changing the server TCP settings, but I am looking for a way to do this in nodejs.

You can implement it very easy:

var connectionsLimit = 1

io.on('connection', function (socket) {

  if (io.engine.clientsCount > connectionsLimit) {
    socket.emit('err', { message: 'reach the limit of connections' })
    socket.disconnect()
    console.log('Disconnected...')
    return
  }

})
