node-addon-api simplifies native Node.js addons development. It offers a C++ API providing abstraction over Node.js's underlying Native Abstractions for Node.js (NAN). This allows developers to create and maintain addons with significantly less code, increasing portability across different Node.js versions. Using node-addon-api avoids managing ABI compatibility complexities directly, streamlining the process of building high-performance modules with native code. It's an essential tool for developers targeting multiple Node.js runtimes.
