node.js - Socket.io io.use fails - TypeError: io.use is not a function -

i'm working on project needs socket handshake session i'm trying code work, got https://www.npmjs.com/package/express-socket.io-session

var app = require('express')(),   server  = require("http").createserver(app),   io = require("socket.io")(server),   session = require("express-session")({     secret: "my-secret",     resave: true,     saveuninitialized: true   }),   sharedsession = require("express-socket.io-session");   // attach session app.use(session);  // share session io sockets  io.use(sharedsession(session));  io.on("connection", function(socket) {      // i've add one...     console.log(socket.handshake.session);      // accept login event user's data     socket.on("login", function(userdata) {         socket.handshake.session.userdata = userdata;     });     socket.on("logout", function(userdata) {         if (socket.handshake.session.userdata) {             delete socket.handshake.session.userdata;         }     });         });  server.listen(3000); 

i run , first got

var io = require("socket.io")(server);                              ^  typeerror: require(...) not function     @ object.<anonymous> (/users/jack/root/sites/scopone/provaric/server.js:8:30)     @ module._compile (module.js:435:26)     @ object.module._extensions..js (module.js:442:10)     @ module.load (module.js:356:32)     @ function.module._load (module.js:313:12)     @ function.module.runmain (module.js:467:10)     @ startup (node.js:136:18)     @ node.js:963:3 

solved adding

io = require("socket.io").listen(server);

and got one

io.use(function(socket, next) {     ^  typeerror: io.use not function     @ object.<anonymous> (/users/jack/root/sites/scopone/provaric/server.js:15:5)     @ module._compile (module.js:435:26)     @ object.module._extensions..js (module.js:442:10)     @ module.load (module.js:356:32)     @ function.module._load (module.js:313:12)     @ function.module.runmain (module.js:467:10)     @ startup (node.js:136:18)     @ node.js:963:3 

any ideas fix this?

socket.io@0.9.17

i had same problem in same context. though question here while,i post approach.

the whole problem used:

var io = require('socket.io'); 

but should be:

var io = require('socket.io')(); 

everything else working without braces @ end apparently io.use not.

instead of passing server did:

app.io = io; 

in /bin/www

  app.io.attach(server); 

hope useful someone.

update: use socket 1.5.2.
