Pull request overview

This PR updates the project’s ObjectWrap unwrapping helper to remain compatible with newer V8 (>= 14), addressing an incompatibility encountered with Electron 41.

Changes:

• Use the V8 >= 14 GetAlignedPointerFromInternalField overload that includes an embedder data type tag.
• Keep backward compatibility by falling back to the pre-V8-14 API via preprocessor guards.

It's a bit more complicated
It no longer works on Node 25.

V8 < 11.4 Until 2023
GetAlignedPointerFromInternalField(int index)
✅ Stable

V8 11.4 – 13.x 2023–2024
GetAlignedPointerFromInternalField(int index, Tag tag)
🔄 Experimental / Changed

V8 14.1+ 2024+
GetAlignedPointerFromInternalField(int index)
✅ Stable (tags removed from public API)

This is also not true, the AI ​​lied
but in the end, the version with doesn't build for me
GetAlignedPointerFromInternalField(int index, Tag tag)
is there a link to the description?

It seems like this only starts with version V8 14.3
on node v25.8.1 used V8 14.1
