Most of cases Heroku is used to deploy, run and manage applications written in Ruby, Node.js, Java, Python, Clojure, Scala, Go and PHP.
To push front end applications bitballon provides easiest way.(you can just Drag/Drop your project files(which should has index files) over there)
https://www.bitballoon.com
I have used this to host an angular application.(As similar to your git repository which is hacker earth hiring challenge)
sample angular with bitballon(Front end app)
OR
USE Heroku
Install Heroku cli in your PC
create nodeJS app heroku portal.
Create app folder copy all front-end app files into that
4.place Server ServerJS in beside app folder.
heroku login, heroku git:clone -a $APPNAME, git add and git commit.
Finally git push heroku master
--> Server JS :
var express = require("express");
var port = process.env.PORT || 8080;
var app = express();
app.use(function(req, res, next) {
var ip = req.headers['x-forwarded-for'] || req.connection.remoteAddress;
res.setHeader('Access-Control-Allow-Credentials', true);
next();
});
var router = express.Router();
app.use('/', router);
app.use(express.static(__dirname + '/app'));
app.listen(port);
console.log('---------------------------------- ');
console.log('Server Started on port: ' + port);
console.log('---------------------------------- ');
Package.json
