NodeJS (Express.js) : How to make the Session global

Question

I know that global vars are a bad practice in javascript and in programming overall, but i want to make my user session available throughout my express.js app, avoiding having to pass the session parameter all over, from my controllers to my models.

How can I best do this?

Thanks!

Answer 1

I ended up solving this like so:

var appendLocalsToUseInViews = function(req, res, next)
{            
    //append request and session to use directly in views and avoid passing around needless stuff
    res.locals.session = req.session;
    next(null, req, res);
}

Then add it to the middleware:

app.use(appendLocalsToUseInViews);
