JavaScript Source Maps Enumeration Tool

jsmapfinder is a tool designed to enumerate JavaScript source maps associated with a given website. Source maps are files that map compressed or minified code back to their original source code, aiding in debugging and understanding the code structure. However, if exposed unintentionally, they can reveal sensitive information about the application's codebase.

npm install -g jsmapfinder
