Node.js API (N-API) Package

This package contains header-only C++ wrapper classes for the ABI-stable Node.js API also known as N-API, providing C++ object model and exception handling semantics with low overhead. It guarantees backward compatibility when used with older versions of Node.js that do not have N-API built-in.

N-API is an API for building native addons. It is independent from the underlying JavaScript runtime (e.g. V8 or ChakraCore) and is maintained as part of Node.js itself. This API will be Application Binary Interface (ABI) stable across versions and flavors of Node.js. It is intended to insulate native addons from changes in the underlying JavaScript engine and allow modules compiled for one version to run on later versions of Node.js without recompilation. N-API guarantees the API and ABI compatibility across different versions of Node.js. So if you switched to a different version of Node.js, you would not need to reinstall or recompile the native addon.

APIs exposed by N-API are generally used to create and manipulate JavaScript values. Concepts and operations generally map to ideas specified in the ECMA262 Language Specification.
