path-mapper

Solves for the new path of srcFilePath given the changes to the directory structure described by directoryChanges. directoryChanges is either a hash that maps the absolute paths of old directories to those of new directories or a function that does the same. srcFilePath is an absolute path.

If no changes are described in directoryChanges that affect the path of srcFilePath, then srcFilePath is returned.

pathMapper = require( 'path-mapper' );
 
dstFilePath = pathMapper( srcFilePath, directoryChanges );
 
// or
 
var url = pathMapper( srcFilePath, function( srcDir ) {
    return '/' + packagePathsToIds[ srcDir ];
} );
