How Can JavaScript Engines Be Embedded in .NET to Enable Safe and Controlled User Extensions?

Embedding a JavaScript Engine in .NET: Managing User-Driven Extensions

When considering the integration of JavaScript engines into the .NET environment, it's essential to address the challenges involved in embedding these engines while maintaining tight control over the application's behavior.

One promising solution is JavaScript .NET, hosted on GitHub. This library implements Google V8, enabling the seamless compilation and execution of JavaScript directly from .NET code. JavaScript .NET empowers you to integrate JavaScript engines into your applications, providing a platform for creating custom user subapplications.

This integration allows developers to leverage the familiarity and accessibility of JavaScript for end-users, without compromising the application's security or stability. By hosting JavaScript code and managing its execution within the .NET environment, developers can confidently provide a sandboxed and controlled environment for user customizations.

For example, in the provided code snippet:

// C# class
public class A
{
    public string Hello(string msg)
    {
        return msg + " whatewer";
    }
}

// JS snippet
var a = new A();
console.log(a.Hello('Call me'));

The integration between JavaScript and .NET enables direct method calls between C# and JavaScript objects, allowing for seamless communication and data exchange. Moreover, it allows the implementation of custom logging and debugging mechanisms within the JavaScript code, further enhancing the development and debugging process.

To explore the possibilities of embedding JavaScript engines into .NET further, the GitHub repository for JavaScript .NET provides resources, discussions, and a codebase for your experimentation.
