deep-clone

Deep cloning of Arrays and plain Objects.

Build Status Coverage Status

$ npm i -S deep-clone

deepClone(obj, [stringFormatter])

Recursively clone nested objects and arrays containing primitive data or nested objects and arrays containing primitive data. Clones Date objects too...

import deepClone from 'deep-clone'
 
const foo = { bar: 'baz' }
const fooClone = deepClone(foo)
 
assert.deepEqual(foo, fooClone)
assert.notEqual(foo, fooClone)
 
const arr = [{ foo: 'bar'}, { baz: 'qux'}]
const arrClone = deepClone(arr)
 
assert.deepEqual(arr, arrClone)
assert.notEqual(arr, arrClone)

Deep clone an Object or Array and format the keys.

import camelCase from 'camelcase'
import deepClone from 'deep-clone'
 
const foo = { bar_baz: 'qux' }
const fooClone = deepClone(foo, camelCase)
 
assert.deepEqual(fooClone, { barBaz: 'qux' })

Or...

import camelCase from 'camelcase'
import { formatKeys } from 'deep-clone'
 
const camelKeys = formatKeys(camelCase)
const arr = [{ foo_bar: 'baz' }, { qux_quux: 'corge' }]
const camelClone = camelKeys(arr)
 
assert.deepEqual(camelClone, [{ fooBar: 'baz' }, { quxQuux: 'corge' }])

Version 2 handles circular references using a Map.

const foo = { bar: 'baz' }
 
foo.qux = [foo]
 
const clone = deepClone(foo)
 
assert.deepEqual(clone, foo)
assert.equal(clone.qux[0], clone)
