But if I put one parameter it was work.
await getFilesSnap() // not work
await getFilesSnap(0) // word
My C++ code like this:
exports->Set(context,
String::NewFromUtf8(isolate, getFilesSnap, v8::NewStringType::kNormal)
.ToLocalChecked(),
v8::FunctionTemplate::New(isolate, getFilesSnap, external)
->GetFunction(context).ToLocalChecked()).FromJust();
I google none of infomation about how to pass none parameter in my function. If you have any link, please tell me.
Thank you.

hi @webbery I'm not sure if the example of function arguments may help?: https://github.com/nodejs/node-addon-examples/tree/master/2_function_arguments/node-addon-api

@helio-frota Thanks. That's not I need. I need function like this:
But in order to work, I must call it like this:

That's is weird, I'm still learning n-api btw. I have a working example here: https://github.com/helio-frota/sandwich/
That is nothing but TS calling JS that calls C++ (n-api) that calls C and not using any extra function parameter in order to work.
JS calling the N-api part here: https://github.com/helio-frota/sandwich/blob/master/jsPart.js#L5
I hope this help in some way

@webbery is your code public?

@webbery you can also trust on the example I shared because it was double checked and fixed by @NickNaso 😎

Here is my code:
https://github.com/webbery/civet/tree/master/caxios
The problem function is
getFilesSnapininterface.cpp. I want to call it withgetFilesSnap()butgetFilesSnap( **anything_except_void** )can work.Why?
