Retrieves all the dependencies for the given script module identifiers, filtered by import types.

Description

It will consolidate an array containing a set of unique dependencies based on the requested import types: ‘static’, ‘dynamic’, or both. This method is recursive and also retrieves dependencies of the dependencies.

Parameters

$idsstring[]required

The identifiers of the script modules for which to gather dependencies.

$import_typesstring[]optional

Import types of dependencies to retrieve: 'static', 'dynamic', or both.
Default is both.

Default:array('static', 'dynamic')

Return
