Its main function is to create a linkage between the original source code and the resulting compiled code. Within a JS file, this connection is facilitated by the inclusion of a reference tag, such as `//# sourceMappingURL`, which points to the source map's location. \n\n# Reason for Absence of Sourcemaps in Network Tab\n\nAs discussed in the Chromium bug tracker https://bugs.chromium.org/p/chromium/issues/detail?id=362913, sourcemaps are not considered standard page resources.\n\nThe intention behind the Network tab is to display resources that are a part of an ordinary page load, reflecting the actual network activity. Sourcemaps, while useful for debugging, do not fall under the category of typical resource loads as they're utilized primarily for development purposes.\n\nIn essence, this means there is no option within Chrome to force sourcemaps to appear in the Network tab due to their categorization outside the scope of normal web page resource loading events.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsymind%2Fbrowser-sourcemap-spy","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fsymind%2Fbrowser-sourcemap-spy","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsymind%2Fbrowser-sourcemap-spy/lists"}
