napi_status napi_resolve_deferred(napi_env env,
                                  napi_deferred deferred,

• [in] env: The environment that the API is invoked under.
• [in] deferred: The deferred object whose associated promise to resolve.
• [in] resolution: The value with which to resolve the promise.

This API resolves a JavaScript promise by way of the deferred object with which it is associated. Thus, it can only be used to resolve JavaScript promises for which the corresponding deferred object is available. This effectively means that the promise must have been created using napi_create_promise() and the deferred object returned from that call must have been retained in order to be passed to this API.

The deferred object is freed upon successful completion.
