Angular uses webpack and all type script files are listed under it. To select your target typescript file, Chrome's Developer tool (F12). Go to Source tab,

Select Chrome "webpack://"->"src/app" -> your typescript file.

Or in older version of chrome follow this path "webpack://"->"."->"src/app" -> your typescript file ( See the image file).
