Hello! I am trying to migrate native module for electron application from nan to napi using addon-node-api wrapper. I am facing a problem with AsyncWorker. Overridden Execute works fine and gets results, but OnOK is never called. Under d...

[out] promise: 关联上面deferred对象的JS Promise对象,用于主线程方法返回。 返回值:返回napi_ok表示转换成功,其他值失败。 2.执行napi_create_async_work异步线程后,将deferred对象,通过napi_queue_async_work将创建的async work添加到队列,由NAPI框架的底层去调度后执行。
