Could you please make async itreator on plain C source example

[vit1251]

Coudl you please provide async iterator implementation on pure C source code example?

[NickNaso]

What do you mean for async iterator could you explain better your need? Could you post an example?

[vit1251]

Example use C impoementation Node source code for:

for await (const item of napi.invoke()) {
  // processing item here...
}

It should stop iteration until iteration protocol is provide next promise item and resolve it.
This may using in process BigData array storage on Node side.

Hi @vit1251 ,

We discussed this in the 13 May Node API meeting.

A JavaScript iterator is just an object that provides a standard structure. I will try to create an example for you and publish it in the examples for node-addon-api.

Thanks, Kevin

Hi @vit1251 ,

We added an async iterator example backed by threadsafe functions in our node-addon-examples repo: https://github.com/nodejs/node-addon-examples/tree/main/threadsafe-async-iterator/node-addon-api

Does this help in your use-case?

Thanks, Kevin

@KevinEady thank you. No, you use deprecated C++ API we use C ABI describe at https://nodejs.org/api/n-api.html page but I will try to deeply view your code and try to catch main principle.

[KevinEady]

I'm not sure what you mean by "deprecated C++ API": node-addon-api is not deprecated at all. There is basically a 1:1 mapping of node-addon-api with the underlying Node-API calls, so it should be fairly straightforward to port. Let me know if you have any questions.

@KevinEady so I got the wrong impression, as I meet with bugs in outdated native C++ modules (Node version mismatch) and assumed that the C variant with the portable ABI is more modern. Thanks.
