Use v8 in addon with node-addon-api?

[yiv1]

If I understand correctly, Node.js has not integrated all the functionality of v8.
I want to use v8 function in my с++ addon written with node-addon-api

https://github.com/nodejs/node/blob/main/deps/v8/src/base/platform/platform-win32.cc

// Convert utf-8 encoded string to utf-16 encoded.
static std::wstring ConvertUtf8StringToUtf16(const char* str) {...

class Win32MemoryMappedFile final : public OS::MemoryMappedFile {...

OS::MemoryMappedFile* OS::MemoryMappedFile::open(const char* name, FileMode mode) {...

OS::MemoryMappedFile* OS::MemoryMappedFile::create(const char* name, size_t size, void* initial) {...

I see several options for implementation:

1. Import с++ functions from v8 (but I don't know how)
2. Import с++ functions or use compiled code from node.js (but I don't know how)
3. Copy the functions into my addon

What variant is better?

node-addon-api is intended for the 80% use case where you don't need more specific APIs from V8. If you truely need those APIs then you should likely use https://github.com/nodejs/nan an live with the fact you will need to recompile for each version of Node.js
