Conditional route middleware

[Nick Poulden]

I'd like to give one of my route middlewares the ability to decide which middlewares come after it based on some condition (in my case, whether a user is logged in). For example:

app.get('/',

    getSession,

    function(req, res, next) {

        if (req.session.user) {

            next([getUserOrders, getUserFavorites, renderUserHomepage]);

        }

        else {

            next([getNewProducts, getLatestDeals, renderHomepage]);

        }

    }

);

Obviously this doesn't work as expected... does anyone have any pointers how I should do this? I'm using Express 3.

you can have middleware that "wrap" other middleware, usage might look
something like:

app.get('/', authenticated(getUserOrders, getUserFavorites),
otherwise(getNewProducts, getLatestDeals), callback);

BUT in my opinion a nicer solution would be to have different routes
and rewrite req.url to point to those. for example

app.get('/', see if user is authenticated and rewrite url, then
next())

app.get('/user', getUserOrdder..., callback)

app.get('/products', ...., callback)

sorry for the short reply, i dont have much time but I hope that kinda
helps

I'll try re-writing req.url - thanks for the tip.
