Package Exports

deep-clone

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (deep-clone) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

deep-clone

Deep cloning of Arrays and plain Objects.

$ npm i -S deep-clone

deepClone(obj, [fn keyFormatter])

Recursively clone nested objects and arrays containing primitive data or objects and arrays containing primitive data.

import deepClone from 'deep-clone'

const foo = { bar: 'baz' }
const fooClone = deepClone(foo)

assert.deepEqual(foo, fooClone) // true
assert.notEqual(foo, fooClone) // true

const arr = [{ foo: 'bar'}, { baz: 'qux'}]
const arrClone = deepClone(arr)

assert.deepEqual(arr, arrClone) // true
assert.notEqual(arr, arrClone) // true

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 arrClone = camelKeys(arr)

assert.deepEqual(arrClone, [{ 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.notEqual(clone.qux, foo.qux)
assert.deepEqual(clone.qux, foo.qux)
assert.equal(clone.qux[0], clone)
