Embedding JavaScript engine into .NET [closed]

Answer 1

Try ReoScript, an open-source JavaScript interpreter implemented in C#.

ReoScript makes your application can execute JavaScript. It has a wide variety of extension methons such as SetVariable, Function Extension, using CLR Type, .Net Event Binding and etc.

Hello World:

ScriptRunningMachine srm = new ScriptRunningMachine();
srm.Run(" alert('hello world!'); ");

And here is an example of script that creates a winform and show it.

import System.Windows.Forms.*;        // import namespace

var f = new Form();                   // create form
f.click = function() { f.close(); };  // close when user clicked on form

f.show();                             // show 

Answer 2

Use JSCRIPT.NET to get a library(dll) of the js . Then reference this dll in your .NET application and you are just there. DONE!

Answer 3

The open source JavaScript interpreter Jint (http://jint.codeplex.com) does exactly what you are looking for.

Edit:
The project has been entirely rewritten and is now hosted on Github at https://github.com/sebastienros/jint

Answer 4

I just tried RemObjects Script for .Net.

It works, although I had to use a static factory (var a=A.createA();) from JavaScript instead of the var a=new A() syntax. (ExposeType function only exposes statics!) Not much documentation and the source is written with Delphi Prism, which is rather unusual for me and the RedGate Reflector.

So: Easy to use and setup, but not much help for advanced scenarios.

Also having to install something instead of just dropping the assemblies in a directory is a negative for me...

V8.NET is a new kid on the block (as of April 2013) that more closely wraps the native V8 engine functionality. It allows for more control over the implementation.

Answer 6

i believe all the major opensource JS engines (JavaScriptCore, SpiderMonkey, V8, and KJS) provide embedding APIs. The only one I am actually directly familiar with is JavaScriptCore (which is name of the JS engine the SquirrelFish lives in) which provides a pure C API. If memory serves (it's been a while since i used .NET) .NET has fairly good support for linking in C API's.

I'm honestly not sure what the API's for the other engines are like, but I do know that they all provide them.

That said, depending on your purposes JScript.NET may be best, as all of these other engines will require you to include them with your app, as JSC is the only one that actually ships with an OS, but that OS is MacOS :D
