Viewers responsible for this format

A source map connects generated JavaScript or CSS positions back to original source locations. Anyfile parses the map, summarizes coverage and lets you query mappings without loading the generated program.

Common question

Does a .map file include the original source?

Sometimes. Anyfile shows sourcesContent when embedded; otherwise it can only display source paths and mappings.
