Heroku provides a checklist for first time and subsequent deployments of apps to their platform. The first time deployment involves creating a Heroku account, committing code to git, installing the Heroku CLI, creating an app, and deploying the app with git. Subsequent deployments only require committing updated code and redeploying. Key steps include specifying the node environment, start script, and ensuring the app listens to the correct dynamic port assigned by Heroku.

Heroku tells which port our app will use,
so we need to make sure we listen to the
post they tell us to
We want to use a specific version of

$brew install heroku
$heroku -v

5. create new app using heroku
$heroku login
Provide heroku credentials email-id and pwd
To create app
$heroku create
o/p will be 2 links -
a) Address to navigate to app using browser
b) Deployment Target - a git repo that we can push our local server data to

6. create new app using heroku
$git remote add heroku <---heroku git repo---->
$git push heroku master

7. create new app using heroku
$git remote add heroku <---heroku git repo---->
