Proposed alternate solution #5
Description
@rivkatzur Thanks for this awesome plugin, it certainly helped me get started integrating chat into my application. However, I faced a few issues when I tried to deploy it in production environment, as my own app was running on one port, and this particular plugin needed to listen on another port of its own.
So, I had to rethink the implementation and finally came up with a solution listed below. The solution is totally non-invasive and would be a good starting point for anyone else who's still looking to add chat to their mean.io app.
app.js
In this file, I just invoke the code that creates and sets up a socket.io object for me, which is then passed to the routes module.
'use strict';
/*
* Defining the Package
*/
var Module = require('meanio').Module;
var MeanSocket = new Module('chat');
/*
* All MEAN packages require registration
* Dependency injection is used to define required modules
*/
MeanSocket.register(function(app, http) {
var io = require('./server/config/socketio')(http);
//We enable routing. By default the Package Object is passed to the routes
MeanSocket.routes(io);
return MeanSocket;
});server/config/socketio.js
This file simply configures the socket.io object. Please note that I had to upgrade meanio module to version 0.5.26 for this work, as http object (express server) is not available in older meanio versions. Moreover, in case you want to use ssl, you can inject https instead of http.
'use strict';
var config = require('meanio').loadConfig(),
cookie = require('cookie'),
cookieParser = require('cookie-parser'),
socketio = require('socket.io');
module.exports = function(http) {
var io = socketio.listen(http);
io.use(function(socket, next) {
var data = socket.request;
if (!data.headers.cookie) {
return next(new Error('No cookie transmitted.'));
}
var parsedCookie = cookie.parse(data.headers.cookie);
var sessionID = parsedCookie[config.sessionName];
var parsedSessionID = cookieParser.signedCookie(parsedCookie[config.sessionName], config.sessionSecret);
if (sessionID === parsedSessionID) {
return next(new Error('Cookie is invalid.'));
}
next();
});
return io;
};routes/chat.js
Finally, use the routes file to define the socket events, etc.
'use strict';
// The Package is passed automatically as first parameter
module.exports = function(MeanSocket, io) {
io.on('connection', function(socket) {
console.log('Client Connected');
socket.on('authenticate', function(data, callback) {
});
});
};Thoughts?
