How are streams handled?

[ackava]

I want to use asp.net core's http3 inside nodejs, however, it seems we have to handle streams for file upload so I wanted to know if you have marshalled .net streams to nodejs streams? If not, how can I implement it?

When you call Edge.js function you are passing it parameters a simple example would be

var edge = require('edge-js');

var helloWorld = edge.func(function () {/*
    async (dynamic input) => { 
        return "Welcome " + input.name + " " + input.surname; 
    }
*/});

helloWorld({name: 'John', surname: 'Smith'}, function (error, result) {
    if (error) throw error;
    console.log(result);
});

Could you create an example where you pass a stream as parameter?

I get it, I can call methods of .net stream inside NodeJS directly.

But to pass it as an input to something inside NodeJS I have to wrap it inside a stream generator. I can do that.

Not entirely sure what you mean, however there are some strict rules that Edge.js follows when marshalling between V8 and CLR runtimes.
Marshalling V8 to CLR:

edge-js/src/double/Edge.js/dotnetcore/coreclrembedding.cs

Line 1365 in f9afabd

public static object MarshalV8ToCLR(IntPtr v8Object, V8Type objectType)

edge-js/src/CoreCLREmbedding/coreclrfunc.cpp

Line 308 in f9afabd

void CoreClrFunc::MarshalV8ToCLR(v8::Local<v8::Value> jsdata, void** marshalData, int* payloadType)

Marshalling CLR to V8:

edge-js/src/double/Edge.js/dotnetcore/coreclrembedding.cs

Line 1106 in f9afabd

public static IntPtr MarshalCLRToV8(object clrObject, out V8Type v8Type)

edge-js/src/CoreCLREmbedding/coreclrfunc.cpp

Line 437 in f9afabd

v8::Local<v8::Value> CoreClrFunc::MarshalCLRToV8(void* marshalData, int payloadType)
