问题 I wanted to know if Express would let me create a route middleware that would be called by default without me explicitly placing it on the app.get() arg list? // NodeJS newb var data = { title: 'blah' }; // So I want to include this in every route function a(){ return function(req, res){ req.data = data; }; }; app.get('/', function(req, res) { res.render('index', { title: req.data.title }); }; I understand I can do app.set('data', data) and access it via req.app.settings.data in the route.
