node-csharp

Installation

Please make sure that you have mono and mcs in your path. To install package run:

npm install node-csharp

Usage

var nodeCSharp = require('../lib/nodeCSharp');

var sourceProgram = `public class Hello1
    {
       public static void Main()
       {
          System.Console.WriteLine("Hello, World!");
       }
    }`;

nodeCSharp.fromSource(sourceProgram, {}, (err, res) => {
    console.log(res);
});

You can also pass input stream:

var nodeCSharp = require('../lib/nodeCSharp');
var s2str = require('string-to-stream');

var sourceProgram = `public class Hello1
{
    public static void Main()
    {
        var readLine = System.Console.ReadLine();
        System.Console.WriteLine(readLine.ToUpper());
    }
}`;

var stdin = s2str("Hello node-csharp!");

nodeCSharp.fromSource(sourceProgram, {stdin}, (err, res) => {
    console.log(res);
});

Promise support

For now library uses standard nodeback api. To use promises you can wrap it using for example promisify-node

var promisify = require("promisify-node");
var nodeCSharp = promisify("node-csharp");   

Motivation

Edge.js is excellent library for using .NET in Javascript but it expects custom program entry. node-csharp is just a wrapper on top of mono so it expects standard Main method.

Crossplatform

Tested on Mac and Linux.
