Guidance on how to share .NET types from .NET-side

[luanmm]

Hello, community!

Considering this code, that interop with a custom scripting (from user code, for instance):

await _node.RunAsync(() =>
{
    var detail = JSValue.CreateObject();
    detail.SetProperty("uuid", Guid.NewGuid().ToString("N"));

    var eventInit = JSValue.CreateObject();
    eventInit.SetProperty("detail", detail);

    var customEvent = JSValue.Global["CustomEvent"].CallAsConstructor("event:test", eventInit);
    JSValue.Global.CallMethod("dispatchEvent", customEvent);
});

Basically, I'm emitting an event from C# that is handled in JS side. But the CustomEvent class needs the parameter being passed as a more complex structure. I was wondering if there is a better way to do it from C# code. Maybe marshalling a native object directly? It would be possible somehow?

Thanks in advance!

Another question regarding this interoperability between platforms: there is a way to share a module (from .NET) from an in-process host, giving access to the state from .NET side?

As an example of what I would try to do:

public class AppExtensionPoint
{
     [JSExport("app")]
     public SampleState Current { get => this; }

    [JSExport("testMethod")]
    public async Task TestMethod(Guid uuid)
    {
        Console.WriteLine($"Value: {uuid}");

        // ...
    }
}

Then, in the JS-side:

import { app } from "my-module"; // Or using the "dotnet.require" from "node-api-dotnet"

await app.testMethod("a119eb9b-5da6-49f1-be5c-41c8a17f5070");

The specifics regarding this scenario would be that the .NET process itself would run the script (it will not run in a Node process), like this:

await _node.RunAsync(async () =>
{
    await _node.ImportAsync("/path/to/script", esModule: true);
});

So (at least what I would expect is) the script could run from .NET process, importing the ".NET structured/generated code" from JS-side and sharing the .NET process state (what would allow scripting as an extension point for the application, which is what I'm trying to do).

Hope I could explain the main idea.

I could even try to do exactly what I'm proposing here, but... this is expected to work? Or there is something that I'm missing here?

Thanks in advance!
