First, use composer to require the new dependency: Add-ons are third-party cloud services that provide out-of-the-box additional services for your application, from persistence through logging to monitoring and more.
By default, Heroku stores 1500 lines of logs from your application.

Scale the number of web dynos to zero: $ composer update Loading composer repositories with package information Updating dependencies (including require-dev) - Installing psr/log (1.0.0) Loading from cache ... In this step you’ll learn how to propagate a local change to the application through to Heroku.
As an example, you’ll modify the application to add an additional dependency (the Cowsay library) and the code to use it.
Settings that are application-scoped are read-only, and can only be changed at design time or by altering the .config file in between application sessions.
You can persist the changes to the settings between application sessions by calling the Save method.
I test it and add additional code snippet to determine whether the app Settings within the app.config changes.
Value); App Settings Section app Setting Section = (App Settings Section)config.
For example, if you migrate your app to a professional dyno, you can easily scale it by running a command telling Heroku to execute a specific number of dynos, each running your web process type.
Scaling an application on Heroku is equivalent to changing the number of dynos that are running.
