javascript - In Node.js/Express, how do I automatically add this header to every "render" response?

Question

I have many of these "controllers":

app.get('/',function(req,res){
    var stuff = { 'title': 'blah' };
    res.render('mytemplate',stuff);
});    

Notice res.render? I want to add this header to every response header I make:

X-XSS-Protection: 0

How can I add that response header automatically?

You probably want to use app.use with your own middleware:

app.use(function(req, res, next) {
    res.header('X-XSS-Protection', 0);
    next();
});
