node.js - Possibilty of writing to a wrong object with callback -


i'm using nodejs socket.io server handling realtime things. there event in socket.io authenticating user. code looks follows:

var io = require('socket.io').listen(8080)  io.on('connection', function(socket) {      socket.on('auth', function(id) {          conn.query('select id u id = ?', id, function(e, result) {              socket.id = result[0].id          })      })  )}

my worries line here:

socket.id = result[0].id

this in callback. when db executed query. question is: there possibility there can wrong assignment lot of of connections @ same time? seems happenend , data got assigned wrong socket object. there better methods reliably things this?

the socket object has built-in field id. http://socket.io/docs/server-api/#

strong textsocket#id:string

a unique identifier socket session, comes underlying client.

your code trying assign different value built-in field, seems bad idea. should try rename "your" id field else authid or userid avoid conflict.
