You can do socket   undefined in erase which socket you have connected  So when want to connected do socket url   So it will look like this  const socketClient   require  socket io-client     let socket      Connect to server socket   socketClient url      When want to disconnect socket   undefined

socket disconnect   can be used only on the client side  not on the server side   Client emit  disconnect   triggers the disconnection event on the server  but does not effectively disconnect the client  The client is not aware of the disconnection   So the question remain   how to force a client to disconnect from server side

Add new socket connections to an array and then when you want to close all - loop through them and disconnect   server side   var socketlist           io sockets on  connection   function  socket            socketlist push socket                  other code for connection here                  close remote sockets     socketlist forEach function socket                    socket disconnect

This didn t work for me     socket disconnect       This did work for me    socket disconnect true    Handing over true will close the underlaying connection to the client and not just the namespace the client is connected to Socket IO Documentation     An example use case  Client did connect to web socket server with invalid access token  access token handed over to web socket server with connection params   Web socket server notifies the client that it is going to close the connection  because of his invalid access token        1  the server code emits socket emit  invalidAccessToken   function data        console log data             4  server receives  invalidAccessTokenEmitReceived  from client     socket disconnect true       5  force disconnect client           2  the client code listens to event    client on  invalidAccessToken    name  fn    gt                3  the client ack emits to server        fn  invalidAccessTokenEmitReceived
