npm install exorcist

Transforms the incoming stream of code by removing the inlined source map and writing it to an external map file. Additionally it adds a source map url that points to the extracted map file.

  • missing-map emitted if no map was found in the stream (the src still is piped through in this case, but no map file is written)
Name Type Argument Description
file String

full path to the map file to which to write the extracted source map

url String <optional>

allows overriding the url at which the map file is found (default: name of map file)

root String <optional>

allows adjusting the source maps sourceRoot field (default: '')

Source:

transform stream into which to pipe the code containing the source map
