sort-object

Sort the keys in an object.

Install

Install with npm:

1$ npm i sort-object --save

Usage

1var sortObj = require('sort-object');

By default, the keys on an object will be sorted in ascending order:

1sortObj({a: 1, c: 2, b: 3});
2//=> {a: 1, b: 3, c: 2}

The second param can be an object of options OR an array of keys:

object

1sortObj({a: 1, c: 2, b: 3}, {keys: ['a', 'b']});
2//=> {a: 1, b: 3}

array

1sortObj({a: 1, c: 2, b: 3}, ['a', 'c']);
2//=> {a: 1, c: 2}

Options

• keys {Array} The returned object will contain only the specified keys, in the same order.
• sort {Function} Sort function to sort the keys using JavaScript's .sort() method.
• sortOrder {String} Valid values are desc or asc, case insensitive.
• sortBy {String} Sort function that is passed the entire object, rather than just the keys - as with the .sort() method.

options.keys

Create a new object with only the given keys.

1var o = {a: 1, c: 2, e: 5, d: 4, b: 3};
2sortObj(o, {keys: ['a', 'b']});
3
4//=> {a: 1, b: 3}

options.sort

Function to be passed to javascript's .sort() method:

1var o = {a: 1, c: 2, e: 5, d: 4, b: 3};
2var obj = sortObj(o, {
3  sort: function (a, b) {
4    return a < b ? -1 : 1;
5  }
6});
7obj;
8//=> {a: 1, b: 3, c: 2, d: 4, e: 5}

options.sortOrder

Valid values are desc or asc, case insensitive:

1var o = {a: 1, c: 2, e: 5, d: 4, b: 3};
2sortObj(o, {sortOrder: 'ASC'});
3//=> {e: 5, d: 4, c: 3, b: 2, a: 1}

options.sortBy

Function that returns an array of keys to sort by:

1var old = {one: 'aa', two: 'bc', three: 'ab'};
2var o = sortObj(old, {
3  sortBy: function (obj) {
4    var arr = [];
5    Object.keys(obj).filter(function(key) {
6      if (/^a/.test(obj[key])) arr.push(key);
7    });
8    return arr.reverse();
9  }
10});
11//=> {three: 'ab', one: 'aa'}
