Installation and Pushing Code

Installation

At root directory of nodejs app

git init
git add .
git commit -m 'initialize'

• (Make sure to install heroku cli)

• heroku create or heroku create appname

If there is already an existing app then we need to change the prev origin to current one by:

heroku git:remote -a appname
For changing app name, remote name has to be changed too.

git remote rename heroku newname

git remote heroku newname
heroku git:remote -a newname

heroku apps: rename newname

or for outside git repository

heroku apps: rename newname —app oldname

git push heroku main

For non-main branch:

git push heroku testbranch:main

In nodejs app:

app.listen(process.env.PORT || 3000,()=>{
	console.log('listening');
})
