## What it is
A header-only C++ wrapper library for Node-API (N-API) that simplifies writing native Node.js addons in C++. It provides C++ object model and exception-handling semantics with low overhead over the C-based Node-API.

## Use cases
- write node.js native addons in c++
- wrap a c++ library for use in node
- build abi-stable native modules for node.js
- use c++ exception handling in node addons
- avoid rewriting addons for every node.js version

## When to choose
- you need C++ performance or access to native libraries from Node.js
- you want ABI stability across Node.js versions via Node-API
- you prefer C++ object model and exceptions over raw C Node-API

## When to avoid
- your addon is pure JavaScript and needs no native code
- you target Node.js versions older than the supported LTS range
- you need a C API directly rather than a C++ wrapper

## Facets
- artifact type: library
- maturity: stable
- function: sdk, developer-tools, plugin-system
- domain: developer-tools, backend, cross-platform
- platform: cpp, cross-platform
- tags: node-api, native-addons, header-only, c++-bindings, napi, nodejs
