With the `node-addon` I don't get any errors but the React Page doesn't show up

Start with src/index.tsx, webpack.config.js, binding.gyp, and the emitted build/Release/greet.node while reproducing the issue with yarn start. Done means the React page loads at the dev-server URL and renders the expected “My React and TypeScript App!” header without errors.

Following the indications found here: https://medium.com/jspoint/a-simple-guide-to-load-c-c-code-into-node-js-javascript-applications-3fcccf54fd32 and here https://github.com/nodejs/node-addon-examples/tree/main/1_hello_world/node-addon-api
I'm trying to understand how to effectively use node-addon-api for later include within electron C++ module.

In a simple react-typescript-webpack app I've put this:

In ./src/ folder:

greeting.h :

std::string helloUser( std::string name );

}

int main() {

    std::string HelloUserString = helloUser("Bob");

    std::cout << HelloUserString << std::endl;

    return 0;
}

Compiling and testing the .cpp file:

raphy@raohy:~/native-greet-module/src$ g++ -std=c++20 greeting.cpp -o greeting
raphy@raohy:~/native-greet-module/src$ ./greeting 
Hello Bob !

index.cpp :

// https://github.com/nodejs/node-addon-examples/blob/main/1_hello_world/node-addon-api/hello.cc

// native C++ function that is assigned to "greetHello" property on "exports" object

Napi::String greetHello(const Napi::CallbackInfo& info) {
    Napi::Env env = info.Env();

    // call "helloUser" function from "greeting.cpp" file
    // WARNING: We are passing hardcoded "MIKE" value for now
    std::string result = helloUser( "MIKE" );

    // return new "Nap::String" value
    return Napi::String::New(env, result);
}

// callback method when module is registered with Node.js
Napi::Object Init(Napi::Env env, Napi::Object exports) {

    // set a key on "exports" object
    exports.Set(
        Napi::String::New(env, "greetHello"), // property name => "greetHello"
        Napi::Function::New(env, greetHello) // property value => "greetHello" function
    );

    // return "exports" object (always)
    return exports;
}

// register "greet" module which calls "Init" method
NODE_API_MODULE(greet, Init)

I executed node-gyp configure :

But I get this output, instead of the expected header message My React and TypeScript App! :

You can find the code in this Repo : https://github.com/raphael10-collab/native-greet-module

What's wrong with my settings? And how to make this simple React-Typescript-Webpack with node-addon showing the react page ?
