var moment = require('moment');
var app = express();
// lets care about body text // short them B)
app.locals.moment = require('moment');
// here ofcourse :|
// app.locals.substrText = function (text,  length) {
//         var substredText  = text.substring(0, length);
//         return substredText;
// };

my router file = dashboard.js

    })
});

module.exports = Router;

and view = dashboard.jade
