The following web-app was built following guidance from the following article: Deploying a Java Rest API to Heroku. To test locally follow the instructions in the article.

You will need a Heroku account to run the web-app and you can create one here: https://www.heroku.com/signup. Once you have created the app you can run the following commands to log into Heroku and deploy the web-app:

    heroku login
    heroku create

You will need to have a credit/debit card linked to Heroku to avail of the free add-ons for this. To start up the DB on Heroku:

    heroku addons:create cleardb:ignite

To get your connection string and update the spring.datasource.url in application properties with the value that is returned from the command: heroku config

You can then push it to Heroku with the following command:

    git push heroku master

Once it has been deployed you will need to run the following to run your app heroku ps:scale web=1 to scale the web-app to 1 instance. Then you can access and update it via commands to Postman or a similar tool.

Accessing the URL provided by Heroku will perform a GET request to the root of the web-app.
