Question

I’ve followed the exact same steps which have always previously worked for me, create application through express, place the module dependencies in the node_modules folder. It appears that the socket.io client-side javascript file isn’t being found.

(I’ve looked at other peoples fixes, which is to include the JavaScript file in a script tab. I have not had to do this for my previous node + socket.io projects).

JavaScript on client:

var socket = io.connect('http://localhost');

JavaScript on server:

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

node_modules folder:

socket.io, which has an internal node_modules folder containing socket.io-client

Error Message:

Uncaught ReferenceError: io is not defined
(anonymous function)

When I include the socket.io client manually:
http://cdn.socket.io/stable/socket.io.js

I get a different error which is:

Uncaught TypeError: Object #<Object> has no method 'connect'
(anonymous function)

Answer 1

On the client, did you do:

<script src="/socket.io/socket.io.js"></script>

before you set the socket variable?
