Description

Context

We are looking for new contributors who can help with enabling C++ API methods in JavaScript side.

First of all read Node.js API Contribution Guide.

What needs to be done?

To avoid extra copies of data, here ov::SharedStreamBuffer should be used. PR with similar change for Python API: https://github.com/openvinotoolkit/openvino/pull/32445/files

Check out existing helper methods and an example how to validate values from javascript.

Contributor guide

Research direction
Study the existing C++ wrapper for Node.js, particularly core wrap.cpp and the helper.hpp file. Understand how ov::SharedStreamBuffer is used in the Python API and adapt it for the JavaScript side to avoid extra data copies in Core.import model().
