Node.js on ChakraCore

This project enables Node.js to optionally use the ChakraCore JavaScript engine. This project is still work in progress and not an officially supported Node.js branch. Please refer to the original PR.

How it works

To enable building and running Node.js with the ChakraCore JavaScript engine, a V8 API shim (ChakraShim) is created on top of the ChakraCore runtime hosting API ([JSRT] (https://msdn.microsoft.com/en-us/library/dn249673(v=vs.94).aspx)). ChakraShim implements the most essential V8 APIs so that the underlying JavaScript engine change is transparent to Node.js and other native addon modules written for V8.

A rebuild node.exe and native addon modules with ChakraCore is required for this to work.
