Node.js + express.js + passport.js : stay authenticated between server restart

express, node.js

Solution

There's an opensource called connect-mongo that does exactly what you need - persists the session data in mongodb

usage example (with a reuse of `mongoose` opened connection) :

var session = require('express-session');
var MongoStore = require('connect-mongo')(session);
var mongoose = require('mongoose');
mongoose.connect('mongodb://localhost/sess');
app.use(express.session({
    secret:'secret',
    maxAge: new Date(Date.now() + 3600000),
    store: new MongoStore(
    // Following lines of code doesn't work
    // with the connect-mongo version 1.2.1(2016-06-20).
    //    {db:mongoose.connection.db},
    //    function(err){
    //        console.log(err || 'connect-mongodb setup ok');
    //   }
    {mongooseConnection:mongoose.connection}
    )        
}));

Problem

I use passport.js to handle auth on my nodejs + express.js application. I setup a LocalStrategy to take users from mongodb My problems is that users have to re-authenticate when I restart my node server. This is a problem as I am actively developing it and don't wan't to login at every restart... (+ I use node supervisor) Here is my app setup : ``` app.configure(function(){ app.use('/static', express.static(__dirname + '/static')); app.use(express.bodyParser()); app.use(express.methodOverride()); app.use(express.cookieParser()); app.use(express.session({secret:'something'})); app.use(passport.initialize()); app.use(passport.session()); app.use(app.router); }); ``` And session serializing setup : ``` passport.serializeUser(function(user, done) { done(null, user.email); }); passport.deserializeUser(function(email, done) { User.findOne({email:email}, function(err, user) { done(err, user); }); }); ``` I tried the solution given on a blog (removed the link as it does not exist any more) using connect-mongodb without success ``` app.use(express.session({ secret:'something else', cookie: {maxAge: 60000 * 60 * 24 * 30}, // 30 days store: MongoDBStore({ db: mongoose.connection.db }) })); ``` EDIT additional problem : only one connection should be made (use of one connexion limited mongohq free service) EDIT 2 solution (as an edition as I my reputation is to low to answer my question by now Here is the solution I finally found, using mongoose initiated connection ``` app.use(express.session({ secret:'awesome unicorns', maxAge: new Date(Date.now() + 3600000), store: new MongoStore( {db:mongoose.connection.db}, function(err){ console.log(err || 'connect-mongodb setup ok'); }) })); ```
