accessing required modules from other modules
- by john smith
I have a bare-bone express application, exactly the one that is created with the express command.
I have installed socket.io and attached it to my server, like this:
var app = express(),
server = http.createServer(app),
io = io.listen(server);
server.listen(8000);
Now, I also have the routes files, which is called like this:
app.get('/', routes.index);
Inside this module I have the following function:
exports.index = function(req, res){
socket.emit('news', { message: "foo" });
};
This obviously leads to a 500 reference error, because the routes file is an exportable module, and obviously has no idea what the socket is, as it is located in the app.js file.
Is there a way I can access this socket object from this, or any other file? Please note that it is attached to the express generated app.
extra: what about getting/setting session data?
Thanks in advance.
