Native addon that can pass typed arrays between threads

[vroad]

I'm looking for a way to load an WebP image, decode it, and send it to main thread from background thread.

I'm using dlopen implementation copied from node source file in the background thread. You may think that it's bad practice, but I want this for my node-based desktop application.

At first, I added dlopen to node-webworker-threads and called that from background thread. DLOpen worked, but crashed while deserializing object. I gave up debugging since I was not sure what was causing the issue.

Then I tried npool. It provides me with better API than node-webworker-threads and seemed not buggy as node-webworker-threads, that's good, but doesn't work with large objects like typed arrays, because this addon uses stringified JSON to communicate between threads.

Do you know any other native addon that supports passing typed arrays between threads?

I ended up creating my own structured clone implementation... https://github.com/vroad/nPool

Hi vroad,

I am the creator of nPool.  I'm glad you found the package easier to work with than node-webworker-threads.  I too ran into issues using it and I don't particularly like the web worker API.

I saw your work with the structured clone implementation.  I like this a lot.  Do you mind if I bring this functionality back into nPool?

Hi inh3,

It's fine to bring my structured clone implementation to your repository, of course.

If you come up with better names for these classes I wrote, please change them.
