deep-keys

Creates an array composed of the own enumerable property names(including nested) of an object.

Note: This kit works great with obj-parse (get and set object properties in a fast and elegant way).

Install

$ npm install --save deep-keys

Usage

deepKeys(obj, intermediate[optional])

var deepKeys = require('deep-keys');

var obj1 = {
  a: 1,
  b: { c: 1 },
  c: { d: { e: 1 }, f: 1 },
  d: { e: { f: { g: 1, h: 2 } } },
  e: 2,
  f: { g: [] }
};
deepKeys(obj1);
//=> ['a', 'b.c', 'c.d.e', 'c.f', 'd.e.f.g', 'd.e.f.h', 'e', 'f.g']

var obj2 = {
  type: 'customer',
  details: {
    name: 'Ariel', age: 26, address: { city: 'Tel Aviv', country: 'Israel' }
  },
  isActive: true
};
deepKeys(obj2);
//=> ['type', 'details.name', 'details.age', 'details.address.city', 'details.address.country', 'isActive']

// intermediate example
var obj3 = {a:{b:{c:1}}};
deepKeys(obj3);       //=> [ 'a.b.c' ]
deepKeys(obj3, true); //=> [ 'a', 'a.b', 'a.b.c' ]

// Dots in key names get escaped
var obj4 = { 'a.': { b: 1} };
deepKeys(obj4) //=> [ 'a\\..b' ]
