Can references be shared between different modules/envs? about abi-stable-node HOT 3 CLOSED

In general I don't think it's safe to use something created with one env, in another env.

from abi-stable-node.

@cutsoy I agree with @mhdawson. It would be safer for modules foo and bar to coordinate via JS. For example, module bar can expose a function that receives as its sole parameter the desired object. Then, the function can be passed into module foo , which will call it with the object. Module bar can then create a second reference to the same object. So, roughly,

foo.sendObject(bar.receiveObject);

where sendObject is implemented as

static napi_value SendObject(napi_env env, napi_callback_info info) {
  napi_value cb, the_object;
  size_t argc = 1;
  napi_get_cb_info(env, info, &argc, &cb, NULL, NULL);
  napi_get_reference_value(env, the_object_ref, &the_object);
  napi_call_function(env, the_object, cb, 1, &the_object, NULL);
}

@cutsoy I hope this answers your question. If you have any further questions, please feel free to re-open this issue or open a new one.
