MongoDB session store for Express and Connect
Fed up from not being able to find a decent mongo store with full control over mongo configuration including replica set support and not face a race condition because mongo connections are not being handled the right way.
Connect-mongo-soajs is a store that gives you full control over mongo configuration. Enjoy an unleashed reliable mongo store :)
This is a standanlone version of soajs connect mongo. You can simply use it as a standalone package as described below.
Installation
$ npm install connect-mongo-soajsUsage
var session = require('express-session');
var MongoStore = require('connect-mongo-soajs')(session);
var store = new MongoStore(dbConfig)dbConfig
The dbConfig object looks like this:
var dbConfig = {
'name' : "",
'prefix' : "",
'servers' : [{host : "", port : ""} ...],
'credentials' : {username : "", password : ""},
'URLParam' : { },
'extraParam' : {db : {}, server : {}, replSet : {}, mongos: {}},
'store': {},
'collection': "sessions",
'stringify': false,
'expireAfter': 1000 * 60 * 60 * 24 * 14 // 2 weeks
}For a full reference regarding URLParam & extraParam please check out mongodb website
Here is an example of dbConfig object:
var dbConfig = {
"name": "core_session",
"prefix": "",
"servers": [
{
"host": "127.0.0.1",
"port": 27017
}
],
"credentials": null,
"URLParam": {
"maxPoolSize": 5
},
"extraParam": {
"db": {
"bufferMaxEntries": 0
}
},
'store': {},
"collection": "sessions",
'stringify': false,
'expireAfter': 1000 * 60 * 60 * 24 * 14 // 2 weeks
}A simple example
var express = require('express');
var session = require('express-session');
var MongoStore = require('connect-mongo-soajs')(session);
var app = express();
var dbConfig = {
"name": "core_session",
"prefix": "",
"servers": [
{
"host": "127.0.0.1",
"port": 27017
}
],
"credentials": null,
"URLParam": {
"maxPoolSize": 5
},
"extraParam": {
"db": {
"bufferMaxEntries": 0,00
}
},
'store': {},
"collection": "sessions",
'stringify': false,
'expireAfter': 1000 * 60 * 60 * 24 * 14 // 2 weeks
}
var sessionConfig = {
"name": "soajsID",
"secret": "this is your session secret shhhhhh",
"cookie": {"path": '/', "httpOnly": true, "secure": false, "domain": "localhost", "maxAge": null},
"resave": false,
"saveUninitialized": false,
"store" : new MongoStore(dbConfig)
};
app.use(session(sessionConfig));

Below is how a configuration object should look like, but Please check out mongodb website
