Question

So I went to Git Bash and typed npm install socket.io I found the the directory in my user folder: C:\Users\weka\node_modules… anyway, I dragged the socket.io folder into my project www folder because I am using WAMP server.

So, here’s my server.js for testing:

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

io.sockets.on('connection', function (socket) {
console.log('Someone connected!');
socket.on('set nickname' , function (nickname) {
socket.nickname = nickname;
console.log(nickname + ' just connected!');
});

});

app.listen(8080);

and I go into cmd and type node C:\wamp\www\gameTest\server.js

and I get the error that it cannot find the module called express. I thought I downloaded socket.io? I am a newb when it comes to GitHub.. so I probably did it wrong. :\

Help?

UPDATE: I found out I hadn’t installed it. OK, I typed npm install express and I now I have express folder in my node_modules folder.

express and socket.io are different libraries. Just npm install express from the root of your app.

Also, make sure that your node dependencies are in a folder called node_modules – that’s the convention used for module resolution. So, you should have a file structure that looks something like:

/some-app
    /node_modules
        /express
        /socket.io
    server.js
