node-finalize-addon

Object finalization based on N-API for Node.js v8.6.0+.
In a nutshell, it allows you to register a callback which will be executed when/if observable object becomes eligible for garbage collection.

Installation

npm install finalize-addon

Usage

const finalize = require('finalize-addon')
 
const obj = ...
finalize(obj, () => {
  // warn if fd/sockets are left open, etc
})

requireing N-API addon in Node.js < v10.0.0 results in Warning: N-API is an experimental feature and could change at any time.. Use NODE_NO_WARNINGS=1 node ... or node --no-warnings ... to suppress.
