res.sendFile(path_to_file); is all you need; it will automatically set the correct headers and transfer the file (it internally uses the same code as express.static). In express versions less than 4, use sendfile instead of sendFile.
You can’t. Heroku sets the PORT variable that you are supposed to bind, and listens on tcp/80.
This should work to ensure that the directory is set up in the right place so that Mongo can find it: sudo mkdir -p /data/db/ sudo chown `id -u` /data/db

The strategy-implementation works in conjunction with passport.authenticate to both authenticate a request, and handle success/failure. Say you’re using this route (which is passed an e-mail address and a password): app.post(‘/login’, passport.authenticate(‘local’, { successRedirect: ‘/loggedin’, failureRedirect: ‘/login’, // see text failureFlash: true // optional, see text as well }); This will call the code in the … Read more
The express router can handle this since 4.0 http://expressjs.com/en/api.html#router http://bulkan-evcimen.com/using_express_router_instead_of_express_namespace.html var express = require(‘express’); var app = express(); var router = express.Router(); // simple logger for this router’s requests // all requests to this router will first hit this middleware router.use(function(req, res, next) { console.log(‘%s %s %s’, req.method, req.url, req.path); next(); }); // this will … Read more
This is a warning that will go away once Express updates to use Connect 3.0 – as a temporary fix, follow the instructions at the top of https://github.com/senchalabs/connect/wiki/Connect-3.0. Specifically, find this line in your app: app.use(express.bodyParser()); And replace it with the following (this is what bodyParser will be in 3.0): app.use(express.json()); app.use(express.urlencoded());
I have a workaround for the adding proper extension of files. If you use path node module var multer = require(‘multer’); var path = require(‘path’) var storage = multer.diskStorage({ destination: function (req, file, cb) { cb(null, ‘uploads/’) }, filename: function (req, file, cb) { cb(null, Date.now() + path.extname(file.originalname)) //Appending extension } }) var upload = … Read more
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 … Read more
