Due to the limitation of node-addon-api, this project has not implemented inheritance yet, so calling the method of superclass from subclass object will report an error, just like

TypeError: Illegal invocation

Related issues are discussed in the following two issues.

node-addon-api#229
node-addon-api#956

In order to temporarily solve this problem, I reexposed the superclass method that needs to be used on the subclass.

It is expected that node-addon-api can really support inheritance.

Sorry, not yet, this requires node to provide inheritance support for the napi mechanism.

Please refer to nodejs/node#38038 for more details.

Hi, I've managed to make inheritance work in my lib node-addon-api-helper. It's complex due to the nature napi designed doesn't match C++ inheritance property. We need hold a pointer to base class in ObjectWrap and static cast the pointer while calling methods. Hope it could help. :)
