lodash-flatkeystree v1.0.0

Install

npm install lodash-flatkeystree

Purpose

Need a way to get all the key paths in an object? Look no further.

Also ignores circular references in an object.

_.keysDeep(object, depth = 1)

Arguments

• object: The object to get keys from
• depth: The number of circular objects to traverse/include. (default 1)

Use

var _ = require('lodash'), keysDeep = require('lodash-flatkeystree');

_.mixin(keysDeep);

var obj = {
  a: {tree: ['that', 'goes', {deep: '!'}]},
  b: [1,2,3,5,8,13, {another: {key: [13,8,5,3,2,1]}}]
};

_.keysDeep(obj);

[ 'a.tree.0',
  'a.tree.1',
  'a.tree.2.deep',
  'b.0',
  'b.1',
  'b.2',
  'b.3',
  'b.4',
  'b.5',
  'b.6.another.key.0',
  'b.6.another.key.1',
  'b.6.another.key.2',
  'b.6.another.key.3',
  'b.6.another.key.4',
  'b.6.another.key.5' ];

Circular with depth > 1

var circularObj = {
  a: {tree: ['that', 'goes', {deep: '!'}]},
  b: [1,2,3,5,8,13, {another: {key: [13,8,5,3,2,1]}}]
};

circularObj.c = {
  cir: circularObj.a,
  something: 'else'
};

_.keysDeep(circularObj, 2);

[ 'a.tree.0',
  'a.tree.1',
  'a.tree.2.deep',
  'b.0',
  'b.1',
  'b.2',
  'b.3',
  'b.4',
  'b.5',
  'b.6.another.key.0',
  'b.6.another.key.1',
