I was wondering if it was possible to use the N-API to give a workerthread access to an object that a different workerthread has created. Although I do not require concurrent access, I currently transfer data by serializing and deserializing it. However, my data is quite big (JSON.stringify().length() returns around 50000000), so I lose quite a bit of time. I know shared byte arrays exist, but serializing my object into those takes the same amount of time. Would N-API give me the possibility to give thread2 access to an object that thread1 has created with low overhead?

This is possible only if your object can be accessed without V8 - ie it does not contain V8 objects. Binary buffers,
TypedArrays work. JS Arrays, JS objects do not. Every worker_thread runs in a different V8 isolate and the V8 object storage is not thread safe and cannot be accessed from outside its main thread.
