9. Create sample Node.js startup File
Create Web.js file with following code
var express = require("express");
var logfmt = require("logfmt");
var app = express();
app.use(logfmt.requestLogger());
app.get('/', function(req, res) {
res.send('Hello World!');
});
var port = Number(process.env.PORT || 5000);
app.listen(port, function() {
console.log("Listening on " + port);
});

10. Create Package.json
 Open root application path in console
 Run “npm init” command and provide all information
 Now run below command
 npm install express logfmt --save

11. Create Package.json
 Add below entry in generated package.json
{
"engines": {
"node": "0.10.x"
}
}

12. Create Procfile
Only one line needs to enter
web: node Web.js

13. Commit to Git
 First Commit to Local
 Then
 Heroku

14. Assign Dyno to your application
 A dyno is a lightweight container running a single
user-specified command
 Assign 1 Dyno to your Heroku application which is free

15. How to check logs on Heroku
 Navigate to your Node.js application folder and run
below command :
