Remove objects on disconnect socket.io
提问by dzm
I'm using Nodejs and Socket.io. When the client connects, new JavaScript objects are created.
我正在使用 Nodejs 和 Socket.io。当客户端连接时，会创建新的 JavaScript 对象。
Do these objects just linger forever? Should they be deleted or removed when the client disconnects? Is it even possible to remove an object? I know delete won't work...
这些物体会永远存在吗？当客户端断开连接时，它们应该被删除还是移除？甚至可以删除对象吗？我知道删除不起作用...
Thanks - I guess this is more of a general question and any suggestions would be really helpful.
谢谢 - 我想这更像是一个一般性问题，任何建议都会非常有帮助。
Thanks!
谢谢！

If you don't cleanup, then yes, they will stay there forever since I assume you are making them global.
如果您不清理，那么是的，它们将永远留在那里，因为我假设您正在使它们成为全球性的。
You should cleanup once a user disconnects by binding to the disconnectevent listener:
一旦用户断开连接，您应该通过绑定到disconnect事件侦听器进行清理：
var clients = {}
sockets.on('connection', function(socket) {
clients[socket.id] = socket;
socket.on('disconnect', function() {
delete clients[socket.id];
});
});
