sorts-object

This tiny and fast module performs the sort of an Array of objects with the property required. The module returns a new copy of the array so the original is not mutated. The module even supports the sort objects (but they get transformed into an array of objects first)

Install

You can install it with npm:

$ npm install --save sorts-object

Usage

The module requires two parameters: The array to sort and the property to use in the sorting:

// Example1: Sorting the countries by the name

const sortObjectsArray = require('sort-objects-array');
const countries = [{'name': 'Colombia', 'code': 'co', 'area': 1197411},
                   {'name': 'Argentina', 'code': 'ar', 'area': 2766890},
                   {'name': 'Brasil', 'code': 'br', 'area': 8511965},
                   {'name': 'canada', 'code': 'ca', 'area': 9984670}]

sortObjectsArray(countries, 'name');
// Returns
// [ { name: 'Argentina', code: 'ar', area: 2766890 },
//   { name: 'Brasil', code: 'br', area: 8511965 },
//   { name: 'Colombia', code: 'co', area: 1197411 },
//   { name: 'canada', 'code': 'ca', 'area': 9984670} ]

The default order is ascending but it's possible to change the order to descending using 'desc' or 'reverse' keyword as a third parameter:

// Example2: Sorting the countries by the largest area

sortObjectsArray(countries, 'area', 'desc');
// Returns
// [ { name: 'canada', 'code': 'ca', 'area': 9984670},
//   { name: 'Brasil', code: 'br', area: 8511965 },
//   { name: 'Argentina', code: 'ar', area: 2766890 },
//   { name: 'Colombia', code: 'co', area: 1197411 } ]

If you prefer you can pass the order as a configuration object using the order property:

// Example3: Sorting the countries by the largest area using config object.
sortObjectsArray(countries, 'area', {order: 'desc'});
// Returns
// [ { name: 'canada', 'code': 'ca', 'area': 9984670},
//   { name: 'Brasil', code: 'br', area: 8511965 },
//   { name: 'Argentina', code: 'ar', area: 2766890 },
//   { name: 'Colombia', code: 'co', area: 1197411 } ]

By default, the module respects the case sensitivity of the values. If you want to override it and ignore it you can pass the flag caseinsensitive in the configuration object.

// Example4: Sorting by name. Case insensitive

sortObjectsArray(countries, 'name', {caseinsensitive: true});
// Returns
// [ { name: 'Argentina', code: 'ar', area: 2766890 },
//   { name: 'Brasil', code: 'br', area: 8511965 },
//   { name: 'canada', 'code': 'ca', 'area': 9984670},
//   { name: 'Colombia', code: 'co', area: 1197411 } ]

Or both:

// Example5: Sorting by name desc and case insensitive

sortObjectsArray(countries, 'name', {order: 'desc', caseinsensitive: true});
// Returns
// [ { name: 'Colombia', code: 'co', area: 1197411 },
//   { name: 'canada', 'code': 'ca', 'area': 9984670},
//   { name: 'Brasil', code: 'br', area: 8511965 },
//   { name: 'Argentina', code: 'ar', area: 2766890 } ]

Finally it can sort objects, converting them first to an array of objects using 'key' and 'value' in each item:

// Example6: Sorting by an object by value

const countriesObj = {
    Colombia: 1197411,
    Argentina: 2766890,
    canada: 9984670,
    NonExistingCountry: null,
    Brasil: 8511965
}

sortObjectsArray(countriesObj, 'value', {order: 'desc'});
// Returns
// [ { key: 'canada', value: 9984670 },
//   { key: 'Brasil', value: 8511965 },
//   { key: 'Argentina', value: 2766890 },
//   { key: 'Colombia', value: 1197411 },
//   { key: 'NonExistingCountry', value: null } ]
