One of the best things Heroku provides is Documentation. Check how to install the Heroku CLI in few steps here:


The install steps generally are

- On the terminal run the login command ​$ heroku login​ ​it will redirect you to the browser page for authentication.
- Or run ​$ heroku login -i​ ​to enter credentials on terminal

3. Deploy your app

Create a new local directory and run ​$ init git,​ or add Heroku app to an existing git tracked directory.

Run ​$Heroky create​ to create a new Heroku App ( a random name will be given)
Or specify your existing app name to add Heroku app to the directory
$ heroku git:clone -a xe-alert-node

Commit your local changes​ $ git add.​ &​ $ git commit -m “Commit Message” then run ​$ git push heroku [BRANCH_NAME] Your application will be deployed to Heroku Dyno now as a web dyno.

To access your app run ​$heroku open​ it will open a new browser window with your app public subdomain.
