Fast and powerful array sorting. Sort an array of objects by one or more properties. Any number of nested properties or custom comparison functions may be used.
Install with npm:
$ npm install --save array-sortInstall with yarn:
$ yarn add array-sortSort an array by the given object property:
var arraySort = require('array-sort');
arraySort([{foo: 'y'}, {foo: 'z'}, {foo: 'x'}], 'foo');
//=> [{foo: 'x'}, {foo: 'y'}, {foo: 'z'}]Reverse order
arraySort([{foo: 'y'}, {foo: 'z'}, {foo: 'x'}], 'foo', {reverse: true});
//=> [{foo: 'z'}, {foo: 'y'}, {foo: 'x'}]arraySort(array, comparisonArgs);- array: {Array} The array to sort
- comparisonArgs: {Function|String|Array}: One or more functions or object paths to use for sorting.
var arraySort = require('array-sort');
var posts = [
{ path: 'c.md', locals: { date: '2014-01-09' } },
{ path: 'a.md', locals: { date: '2014-01-02' } },
{ path: 'b.md', locals: { date: '2013-05-06' } },
];
// sort by `locals.date`
console.log(arraySort(posts, 'locals.date'));
// sort by `path`
console.log(arraySort(posts, 'path'));var arraySort = require('array-sort');
var posts = [
{ locals: { foo: 'bbb', date: '2013-05-06' }},
{ locals: { foo: 'aaa', date: '2012-01-02' }},
{ locals: { foo: 'ccc', date: '2014-01-02' }},
{ locals: { foo: 'ccc', date: '2015-01-02' }},
{ locals: { foo: 'bbb', date: '2014-06-01' }},
{ locals: { foo: 'aaa', date: '2014-02-02' }},
];
// sort by `locals.foo`, then `locals.date`
var result = arraySort(posts, ['locals.foo', 'locals.date']);
console.log(result);
// [ { locals: { foo: 'aaa', date: '2012-01-02' } },
// { locals: { foo: 'aaa', date: '2014-02-02' } },
// { locals: { foo: 'bbb', date: '2013-05-06' } },
// { locals: { foo: 'bbb', date: '2014-06-01' } },
// { locals: { foo: 'ccc', date: '2014-01-02' } },
// { locals: { foo: 'ccc', date: '2015-01-02' } } ]If custom functions are supplied, array elements are sorted according to the return value of the compare function. See the docs for Array.sort() for more details.
