Accessing Express.js req or session from Jade template

In express 3.x, dynamicHelpers have been removed so you will need to use a combination of middleware and res.locals. Let's say we want to access req.query in a /signup/new view:

localQuery = function(req, res, next) {
  res.locals.query = req.query;
  next();
};

newSignup = function(req, res) {
  res.render('signup/new');
};

app.get('signup/new', localQuery, newSignup);

Now any route which uses the localQuery middleware, will have res.locals.query set. This can then be accessed in your view as query.

Just add

app.use(express.cookieParser());
app.use(express.session({secret: '1234567890QWERTY'}));
app.use(function(req,res,next){
    res.locals.session = req.session;
    next();
});

Before

app.use(app.router);

and get your session in jade

p #{session}
