Socket.io store implementation using mongodb.
This is a socket.io store using mongo based on the socket.io-mongo module by Oleg Slobodskoi. I updated the store to support the most recent versions of socket.io, mongo, and mubsub.
Version 0.9.2 works with mubsub version 1.02. Note that the capped collection storage format has changed from that in versions <= 0.9.1.
Install
npm install mong.socket.io
Usage example
var socketio = require('socket.io'),
express = require('express'),
MongoStore = require('mong.socket.io'),
app = express.createServer(),
io = io.listen(app);
app.listen(8000);
io.configure(function() {
var store = new MongoStore({url: 'mongodb://localhost:27017/yourdb'});
store.on('error', console.error);
io.set('store', store);
});
io.sockets.on('connection', function (socket) {
socket.emit('news', { hello: 'world' });
socket.on('my other event', function (data) {
console.log(data);
});
});
Options
// Default options
{
collectionPrefix: 'socket.io.' // collection name is prefix + name
,streamCollection: 'stream' // capped collection name
,storageCollection: 'storage' // collection name used for key/value storage
,nodeId: null // id that uniquely identifies this node
,size: 100000 // max size in bytes for capped collection
,num: null // max number of documents inside of capped collection
,url: null // db url e.g. "mongodb://localhost:27017/yourdb"
,host: 'localhost' // optionally you can pass everything separately
,port: 27017
,db: 'mongsocketio'
};
new MongoStore(options);
Run tests
These tests are based on the same suite from socket.io-mongo and written using mocha.
