socket.io.js not found on client

Question

This question has been asked previously but haven\'t found any solution in prior replies.

Socket.IO gives me two problems:

1. server side gave this error - ER

Answer 1

The problem here is that you're telling Socket.IO to listen on a server that does not yet exist, causing an EACCES and therefore not serving the client file. This is what you're doing:

// the HTTP server doesn't exist yet
var io = require('socket.io').listen(server);
var server = http.createServer();

And if you saw in your server-side error console, you get this:

info: socket.io started
warn: error raised: Error: listen EACCES

To fix this, move your listen function to after the server is created:

var server = http.createServer();
var io = require('socket.io').listen(server);

Once Socket.IO listens properly, it will automatically serve the client file to /socket.io/socket.io.js. You don't need to find it or serve it manually.
