Documentation
This module returns a constructor for SourceMapIndexGenerator
.
new SourceMapIndexGenerator(startOfSourceMap)
To create a new one, you must pass an object with the following properties:
-
file
: The filename of the generated source that this source map is associated with. -
sourceRoot
: An optional root for all relative URLs in this source map.
SourceMapIndexGenerator.prototype.addIndexMapping(mapping)
