Node.js header-only C++ wrapper classes

 node-addon-api contains header-only C++ wrapper classes which simplify
 the use of the C based Node-API provided by Node.js when using C++. It
 provides a C++ object model and exception handling semantics with low
 overhead.
 .
 There are three options for implementing addons: Node-API, nan, or direct
 use of internal V8, libuv and Node.js libraries. Unless there is a need for
 direct access to functionality which is not exposed by Node-API as outlined
 in C/C++ addons in Node.js core, use Node-API.
 .
 Node.js is an event-based server-side JavaScript engine.
