A short demonstration of how to use AppMaps to shorten the time it takes to get productive on a new-to-you codebase.

I use the open source extension for VS Code called AppMap, and the ecommerce Rails application Solidus as an example.

AppMap works by recording the code execution paths of your app. A good way to create AppMaps is by recording unit, functional or integration test cases.

To check it out search for 'AppMap' in the VS Code extensions tab or in the VS Code marketplace.
