Filters on express.js

Question

I want to do a filter like rails before filter on express.js. I have a file named photo.js where I'm putting all my photo related routes on there. But I need to redirect user that is not authenticated on my system to the login page. I want to do an beforeFilter so then I dont need to put that logic in all my routes...

Thanks

Answer 1

If you want to keep everything in your photo.js file, I think a better approach is to use app.all and pass multiple callbacks (which work like middleware in routing) built into the app routing. For instance

app.all('/photo/*', requireAuthentication, loadUser);

app.get('/photo/view', function(req, res) {
   res.render('photo_view');
});

app.get('/photo/list', function(req, res) {
   res.render('photo_list');
});

Where requireAuthentication and loadUser are functions.

Take a look the documentation for app.VERB and app.all at http://expressjs.com/api.html#app.all

There are extensions or higher-level frameworks like express-resource.
