Example Node.JS app to deploy Heroku app from Github.

https://heroku-github-deploy.herokuapp.com/

mkdir heroku-github
cd heroku-github
npm init

npm install --save express

const express = require("express");
const app = express();
const PORT = process.env.PORT || 3000;

app.get("/", (req, res) => res.send("Hello World!"));

app.listen(PORT, () => console.log(`Example app listening on port ${PORT}!`));

Note process.env.PORT is necessary to deploy in heroku

heroku will run npm start on deploy. You can change this command by setting Procfile : Heroku Procfile

"scripts": {
    "start": "node index.js"
}

git init
git add .
git commit -am "Inital Commit"
git remote add origin https://github.com/acc/heroku-github.git
git push origin master

Replace https://github.com/acc/heroku-github.git with the git repository you want.

You can also create a Github repository first and clone it.

heroku login
heroku create heroku-github-deploy

heroku-github-deploy is the app name. Change this with desired app name or heroku will generate random name if null

In your newly created heroku-github-deploy dashboard, go to

• Deploy
• Choose Github in Deployment method
• Type in repository name : in this case heroku-github
• Click Search and click Connect

• Choose Enable Automatic Deploys if you want. This will set heroku to deploy everytime you push a commit to github
• Click DeployBranch and done
