Error when trying to load libnode from C# code

[luanmm]

Hello, dear maintainers/supporters!

I tried to build NodeJS from the fork suggested in #107 (the v20 branch), but even the build working and producing a libnode.so.115 in the <nodejs_root>/out/Release directory, I've got this error when trying to create the environment from C# code:

node:internal/bootstrap/switches/is_embedded_env:18
const internalLoader = new ESMLoader();
                       ^

TypeError: ESMLoader is not a constructor
    at node:internal/bootstrap/switches/is_embedded_env:18:24
    at node:internal/main/embedding:18:34

Node.js v20.0.0

This is the way I'm doing it in C# code:

var libnodePath = "<nodejs_root>/out/Release/libnode.so.115";

var nodejsPlatform = new NodejsPlatform(libnodePath);

var nodejs = nodejsPlatform.CreateEnvironment(); // Here the error was thrown

Am I doing something wrong, perhaps?

For the context: I'm working on Linux (x86_64 architecture).

Your code looks fine. Sorry I haven't seen that ESMLoader error and I'm not sure how to fix it. You might try the v19 branch instead of the v20 branch; I'm not sure I tested the v20 branch.

We haven't been focusing as much on the libnode embedding scenarios lately, though I do intend to get back to that soon.

Just to post a feedback: it worked well with v19 (at least the error now is in my "dynamic code" from .NET side), so I think this problem is indeed with v20. I just don't know yet how to do things how I need, like getting results (in .NET) from an external script.js that exports some function calls, for instance.

In my scenario, I would not write .NET code that runs in Node, but would run JS in Node and interop with the .NET system (via JSExports and by calling script exports, like I stated above).

Thanks for the attention, @jasongin. Congratulations for the work here in this project. Hope it can evolve and stabilize soon!
