I’m trying out a .NET solution with Jurassic to call a javascript file in the root folder that will do a fetch(url). Unfortunately, I get a Jurassic.JavaScriptException: 'SyntaxError: Unexpected token 'import' in expression.' error while testing due to the import fetch from "node-fetch"; line I need to use the fetch command. While I’m able to do this in a javascript solution in Visual Studio 2022 with no problems, when I try to do it in a C# solution, I have this error, I assume it’s because the dependencies for node and node-fetch I installed through npm are handled differently, is there a way to resolve this?

The .cs code:

using Jurassic;

var engine = new Jurassic.ScriptEngine();
engine.ExecuteFile(@"script.js");
engine.Execute("fetch('myurl')");

The app.js script:

import fetch from "node-fetch";

The C# solution

The package.json is as follows:

{
  "name": "JurassicTest",
  "version": "1.0.0",
  "type": "module",
  "dependencies": {
    "node": "^18.20.4",
    "node-fetch": "^3.3.2"
  }
}

Is there a way I can compile the javascript solution that’s working correctly separately and then call it through the .NET/Jurassic? I tried it but I couldn’t get it to work.

I also tested Jint but it has the same effect.

Thanks for the help.
