Approved Edge.js: V8 in Fougerite?

[mikec]

I am looking at Edge.js. It has a disadvantage compared to Jint. It requires installing node.exe for Windows on the Rust server host. But it's far more powerful than Jint. C# code called from Javascript is compiled on the spot. Javascript doesn't have to deal with types or anything like that. You just pass a block of C# code as a commented block of text, and Edge unwraps it and compiles it on the spot.

An edge connects two nodes. This edge connects Node.js and .NET. V8 and CLR/Mono - in process. On Windows, MacOS, and Linux.

You can script C# from a Node.js process:

var edge = require('edge');

var helloWorld = edge.func(function () {/*
  async (input) => {
    return ".NET Welcomes " + input.ToString();
  }
*/});

helloWorld('JavaScript', function (error, result) {
  if (error) throw error;
    console.log(result);
  });

You can also script Node.js from C#:

using System;
using System.Threading.Tasks;
using EdgeJs;

class Program
{
  public static async void Start()
  {
    var func = Edge.Func(@"
    return function (data, callback) {
      callback(null, 'Node.js welcomes ' + data);
    }
  ");

    Console.WriteLine(await func(".NET"));
  }

  static void Main(string[] args)
  {
    Task.Run((Action)Start).Wait();
  }
}

Edge.js enables you to run Python and Node.js in-process.
Install edge and edge-py modules:

npm install edge
npm install edge-py

In your server.js:

var edge = require('edge');

var hello = edge.func('py', function () {/*
  def hello(input):
  return "Python welcomes " + input
    lambda x: hello(x)
  */});

hello('Node.js', function (error, result) {
  if (error) throw error;
    console.log(result);
  });

Run and enjoy:

$>node py.js
Python welcomes Node.js

Do you seriously have to use lambda at calling py code? Nah nah nah. I would rather stay at the original Python.
