You can, but do not need to, use the express-flash module for flash messaging. The req.session and res.locals objects exposed by the express-session module provide an avenue for writing your own flash middleware to more precisely meet your needs. This one is adapted from Ethan Brown's book, Web Development with Node & Express.

app.use(function(req, res, next){
  // if there's a flash message in the session request, make it available in the response
  res.locals.flash = req.session.flash;
  // then delete it
  delete req.session.flash;
  next();
});

Set the flash message using req.session.flash before redirecting to the target route.

req.session.sessionFlash = {
  type: 'success',
  message: 'This is a flash message using custom middleware and express-session.'
}

Retrieve the flash message using res.locals.flash in the target route's res.render method.

res.render('index', { flash: res.locals.flash });

See my Gist below for more details about flash messaging in Express 4.

Yes, you can use express-flash:

app.use(flash());
...

app.get('/redirect', function (req, res) {
  req.flash('info', 'Flash Message Added');
  res.redirect('/');
});

You data are acessile in res.locals.messages so in your views just in messages var.

express flash is based on connect flash. It uses sessions to transmit messages.

If you are using locomotive

Locomotive builds on Express, preserving the power and simplicity you've come to expect from Node.

so:

module.exports = function() {

  ...
  this.use(express.bodyParser());
  this.use(express.session({ secret: 'keyboard cat' }));
  this.use(flash());
  ...
}
