node.js - 套接字断开连接时是否必须删除事件侦听器？

Question

在 socket.io 中，当客户端与服务器断开连接时，disconnect会在服务器中为套接字触发事件。我必须removeAllEventListeners()从插座$events吗？或者当套接字死亡时它会自动发生吗？我听说如果我不这样做，内存泄漏可能会出现在服务器上......

Answer 1

After digging through the socket.io source, the socket object (which is the EventEmitter) is deleted when the client disconnects so it is not necessary to manually call removeAllListeners.
