Question

мой код server.js:

var express = require('express'); 
var app = express(); 


// set the view engine to ejs 
app.set('view engine', 'ejs'); 
app.use(express.static(__dirname + '/dist')); 
if (par.query.login) { 


var data={ 
    "user": { 
     "displayName": "fares alkhawaja", 
     "username": "elkhawajah" 
    }, 
    "profile": { 
      "photo":"null", 
      "fullName": "fares sameer alkhawaja" 
    }, 
    "balance": { 
     "overall": 200, 
     "outstanding": 149 
    }, 
    "currentTasks": [{ 
     "isProject": false, 
     "id": "1234", 
     "title": "Build NodeJS Application",

     "prize": "$500",

     "prize": "$500", 
     "project": "topcoder", 
     "holder": "fares" 
    }], 
    "timeline": [{ 
     "title": "Fares uploaded a new submission", 
     "project": "tasqat", 
     "task": "Build new endpoint", 
     "date": new Date(), 
     "handle": "fares" 
    }, { 
     "title": "Fares uploaded a new submission", 
     "project": "tasqat", 
     "task": "Build new endpoint", 
     "date": new Date(), 
     "handle": "fares" 
    }] 
} 
} 
app.get("/dashboard", function(req, res) { 

//send Jsondata to /view/dashboard.ejs 
res.render('dashboard', data); 

}); 

app.listen(process.env.PORT); 
console.log(process.env.PORT + ' is the magic port'); 

моя проблема в том, что мне нужно использовать req.query.login ... если req.query.login {возвращать данные} еще {не возвращают ничего }

например .. когда я использую http://localhost:3000/dashboard данные не должны возвращать ничего, но если пользователь в http://localhost:3000/dashboard?login=true должен вернуть данные ... любую помощь?

По Вашему желанию контроллера образца с условием для query params

var userData = {...}; //your data for user 

Вашего контроллера будет что-то вроде этого

app.get("/dashboard", function(req, res) { 

    var isLoggedIn = req.query.login; //assuming route as /dashboard?login=true 
    var data = isLoggedIn? userData : {}; //empty object or null, whatever you want 

    res.render('dashboard', data); 

});
