node.js - Send variables to all routes in exressjs -

using nodejs/expressjs build apis web app, want send variables apis, such site title , description , on.

i stumbled upon old solution using dynamichelper() no longer in use. new approach so?

easiest thing put in middleware attaches response object locals (those show in views automatically). like:

app.use(function(req,res,next) {    res.locals = {      title : 'your title',      description : 'your description'    };    return next(); }); 

** edit account api endpoints have since each endpoint responsible own object, like:

app.get('/whatever', function(req,res){    var json = {};      // whatever build json    json.metadata = res.locals; // or whatever common stuff    res.send(json); } 

this keeps 'common' stuff in 1 part of json response.
