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.
