recursive-object-proxy

recursive-object-proxy

Like ES6 proxies but deeper. Will notify you whenever a property of an object is updated, no matter how nested it is.

npm i recursive-object-proxy

const proxyObject = require('recursive-object-proxy');
 
const o = {
  a: [
    1, 2, 3, 4, [ 5, 6, 7]
  ],
  b: {
    c: { d: [1, 2, 3], e: 5 }
  }
};
 
const obj = proxyObject(o, (path, val, isRemoved) => {
  console.log('proxy notification: ');
 
  if (isRemoved) {
    console.log(`removed ${path}`);
  } else {
    console.log(`${path} =`, val);
  }
});
 
obj.a[3] = { bb: 22, cc: 44 };
// console output: proxy notification: a[3] = { bb: 22, cc: 44 }
