ChakraCore is the core part of the Chakra Javascript engine that powers Microsoft Edge

ChakraCore

ChakraCore is the core part of Chakra, the high-performance JavaScript engine that powers Microsoft Edge and Windows applications written in HTML/CSS/JS. ChakraCore supports Just-in-time (JIT) compilation of JavaScript for x86/x64/ARM, garbage collection, and a wide range of the latest JavaScript features. ChakraCore also supports the JavaScript Runtime (JSRT) APIs, which allows you to easily embed ChakraCore in your applications.

You can stay up-to-date on progress by following the MSEdge developer blog.

Building ChakraCore

You can build ChakraCore on Windows 7 SP1 or above, and Windows Server 2008 R2 or above, with either Visual Studio 2013 or 2015 with C++ support installed. Once you have Visual Studio installed:

• Clone ChakraCore through git clone https://github.com/Microsoft/ChakraCore.git
• Open Build\Chakra.Core.sln in Visual Studio
• Build Solution

More details in Building ChakraCore.

Using ChakraCore

Once built, you have a few options for how you can use ChakraCore:

• The most basic is to test the engine is running correctly with the ch.exe binary. This app is a lightweight hosting of JSRT that you can use to run small applications. After building, you can find this binary in: Build\VcBuild\bin\[platform+output] (eg. Build\VcBuild\bin\x64_debug)
• You can embed ChakraCore in your applications - see documentation and samples.
• Finally, you can also use ChakraCore as the JavaScript engine in Node. You can learn more by reading how to use Chakra as Node's JS engine

A note about using ChakraCore: ChakraCore is the foundational JavaScript engine, but it does not include the external APIs that make up the modern JavaScript development experience. For example, DOM APIs like document.write() are additional APIs that are not available by default and would need to be provided. For debugging, you may instead want to use print().
