Express.js rest api not working on heroku

Question

I've written a basic node.js application, it's working on local with the command : node app.js but not in heroku here is my package.json

{
  "name": "express-rest-youness",
  "version": "1.0.0",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "description": "",
  "dependencies": {
    "express": "^4.16.2",
    "express-rest": "^1.0.4"
  }
}

and my app.js

 var express = require('express'),
    expressRest = require('express-rest');

 var app = express();
var rest = expressRest(app);

var records = [
    {value: 'Apple'},
    {value: 'Banana'}
];

rest.get('/api/food', function(req, rest) {
    rest.ok(records);
});

rest.get('/api/food/:id', function(req, rest) {
    var record = records[req.params.id];
    if (record) rest.ok(record);
    else rest.notFound();
});

rest.put('/api/food/:id', function(req, rest) {
    records[req.params.id] = req.body;
    return rest.accepted('/api/food/' + encodeURI(req.params.id));
});

rest.post('/api/food', function(req, rest) {
    records.push(req.body);
    rest.created('/api/food/' + (records.length - 1));
});

rest.delete('/api/food/:id', function(req, rest) {
    delete records[req.params.id];
    rest.gone();
})


app.listen(8080);

when trying to access the heroku app i get :

Application error An error occurred in the application and your page could not be served. If you are the application owner, check your logs for details.

Thanks :)

Have you created a Procfile? I'd suggest to familiarize yourself with this tutorial.

I solved it by logging in into heroku dashboard and then app settings and there i specified config vars

You need to get more information on what the error is, such as requesting for the log message, then you can tell if this proffered solution fits into this scenario
