Adding a Global Router Param with Express 4.11 - node.js

Question

I am trying to create a global param that will be used by my Router with Express 4.11. The general function of this is that I am using router.all('/*',function(){}); This method is creating a list of all my routes to dynamically create a navbar in a partial jade template. I can pass the list to the response but I want to not have to call this on every route method I create i.e
router.all('/*',function(res,req,next){
var links = [];
console.log('Being Called...');
for(var i=0; i< router.stack.length; i++) {
var route = router.stack[i];
if(route['route'].path !== '/*'
&& route['route'].path !=='/favicon.ico'){
var name = (route['route'].path !=='/')? route['route'].path.toLowerCase().replace('/','') : "Home";
var active = (route['route'].path === url.parse(res.originalUrl).pathname)? true: false;
links.push({
name: name,
path: route['route'].path,
active: active
});
}
}
if(links.length > 0) {
console.log(res.locals);
res.set('appLinks',links);
}
next();
});
/*GET home page*/
router.get('/', function(req, res, next) {
res.render('index', {title: 'Home', appLinks: req.appLinks});
});
I want that appLinks to be a global param that is used by all of my routes. How do I go about this? or am I over thinking it and should just add that small line of code?
Thank you for the help.

You shouldn't use router.all but instead place following before any router.get or .post or whatever
router.use(function(req,res,next){
var links = [];
//your code here
res.locals.appLinks = links;
next();
});
anything added to res.locals is available in views so there's no need to pass it to res.render(...)
