node-addon-api-helper

Based on node-addon-api, node-addon-api-helper(naah) provides a more convenient, type-safe and boilerplate-less way to write Node.js C++ addons.

Features:

• Automatically transform values between JavaScript and C++
• Automatically register exports
• Class binding (with inheritance)
• Custom object type
• Thread safe function
• Create async work and return promise
• Can be used together with original node-addon-api, no need to rewrite all
• Pure header, can be easily integrated

QuickStart

npm install node-addon-api node-addon-api-helper

Add following content to your GYP file.

{
  'include_dirs': [
    "<!(node -p \"require('node-addon-api').include_dir\")",
    "<!(node -p \"require('node-addon-api-helper').include_dir\")",
  ]
}

naah heavily depends on C++17, if you haven't configured your project on C++17, have a look at naah.gypi as an example.

A hello world example :

#include <naah.h>

uint32_t add(uint32_t a, uint32_t b) {
  return a + b;
}

NAAH_REGISTRATION {
  naah::Registration::Function<add>("add");
}
