About Source Maps Monitor Tool
The tool just displays the file’s origin, which may have a source map URL in its comment. The below pictures are various frames of the webpage, with the GFG one being the main one. When you expand it, you get all the requested file URLs, SHA-256 hashes, and load statuses. These listed files are also expandable to view the sourceMappingURL comment loader status.
If you want to check all the source maps used by the webpage, then Edge provides the Source Maps Monitor Tool to view all the source maps used for converting minified code received from the server to the actual source code.
Source Maps Monitor Tool in Microsoft Edge
The Source Maps Monitor tool is used to monitor the source maps that will be used to generate the original source code that is being requested by the webpage. When a website requests files from the server, the server does not send the original code but instead minifies it to compress the file, improving loading time. The webpage uses source maps to change the minified code to your original code.
