key-sort v0.0.3

key-sort

Introduction

Sorts an array by key, maintaining key to data correlations. This is useful mainly for associative arrays. This is a implementation of PHP ksort() without any sort_flags.

To convert in object/array into associative array, please see object-to-associative-array

Installation

npm install key-sort

Requirements

NODE v0.8.0 or higher

I/O

Input

• Input should always be an associative array.
• Provided array should contain objects and each object should have only one property.
• Property value can be either primitive data types or another associative array.

Output

• Returns array sorted by property name.
• Also modifies input array.
• Deep sorting is default.
• Pass false for not nesting sort.

Examples

Simple Sort

const keySort = require('key-sort');

let arr = [
  {world: 'world'},
  {middle: 'hello'},
  {greeting: 'Welcome to'}
];

let sortedArr = keySort(arr);
// [{greeting: 'Welcome to'},{middle: 'hello'},{world: 'world'}]

Deep Sort

const keySort = require('key-sort');

let arr = [
  {x: 1},
  {a: [
    {f: 365},
    {d: 25}
  ]}
];

let sortedArr = keySort(arr);
// [{"a" :[{"d" :25},{"f" :365}]},{"x" :1}]

Shallow Sort

const keySort = require('key-sort');

let arr = [
  {x: 1},
  {a: [
    {f: 365},
    {d: 25}
  ]}
];

let sortedArr = keySort(arr, false);
// [{"a" :[{"f" :365},{"d" :25}]},{"x" :1}]
