# Node API for .NET: JavaScript + .NET Interop

This project enables advanced interoperability between .NET and JavaScript in the same process.

 - Load .NET assemblies and call .NET APIs in-proc from a JavaScript application.
 - Load JavaScript packages and call JS APIs in-proc from a .NET application.

Interop is high-performance and supports TypeScript type-definitions generation, async
(tasks/promises), streams, and more. It uses [Node API](https://nodejs.org/api/n-api.html) so
it is compatible with any Node.js version (without recompiling) or other JavaScript runtime that
supports Node API.

:warning: _**Status: Public Preview** - Most functionality works well, though there are some known
limitations around the edges, and there may still be minor breaking API changes._

### Documentation

Getting-started guidance, feature details, and API reference documentation are published at
https://microsoft.github.io/node-api-dotnet

### Minimal example - JS calling .NET
```JavaScript
// JavaScript
const Console = require('node-api-dotnet').System.Console;
Console.WriteLine('Hello from .NET!'); // JS writes to the .NET console API
```

### Minimal example - .NET calling JS
```C#
// C#
interface IConsole { void Log(string message); }

var nodejs = new NodejsPlatform(libnodePath).CreateEnvironment();
nodejs.Run(() =>
{
    var console = nodejs.Import<IConsole>("global", "console");
    console.Log("Hello from JS!"); // C# writes to the JS console API
});
```
