Title
Body
I'm trying to separate my socket.io code into a separate file (socket.js) from my main file (app.js). However, I need to define my io object in app.js, which is also used in my socket.js file. Currently, I set io as a global variable so it is accessible from app.js ( Global Variable in app.js accessible in routes? ), but I understand this is bad practise. Is there a better way to do this (can injection work in this case, as I need to export a variable from the app.js to socket.js rather than the other way round)? Thank you! app.js var app = express(), server = require('http').createServer(app); //KIV -> io is set as a global variable io = require('socket.io').listen(server); require('./socket'); socket.js io.sockets.on('connection', function(socket) { //xxx }
