Add DISABLE_CLEAR_CONSOLE environment variable to allow developers to disable the clearing of the console during app startup. Useful if running multiple services at the same time and one service fails during startup.
Suggested usage in package.json: DISABLE_CLEAR_CONSOLE=true npm start
Note: this variable will prevent any usage of clearConsole.

Testing: Add suggested change to package.json, run code and notice the other service logs still in the console once the app starts.
