sort-on

What is sort-on?

The sort-on npm package allows you to sort an array of objects based on the values of specific properties. It provides a simple and efficient way to perform sorting operations on complex data structures.

What are sort-on's main functionalities?

Sort by a single property

This feature allows you to sort an array of objects by a single property. In this example, the array of objects is sorted by the 'age' property.

const sortOn = require('sort-on');
const data = [
  {name: 'John', age: 25},
  {name: 'Jane', age: 22},
  {name: 'Jim', age: 30}
];
const sortedData = sortOn(data, 'age');
console.log(sortedData);

Sort by multiple properties

This feature allows you to sort an array of objects by multiple properties. In this example, the array is first sorted by 'age' and then by 'height' for objects with the same age.

const sortOn = require('sort-on');
const data = [
  {name: 'John', age: 25, height: 180},
  {name: 'Jane', age: 22, height: 170},
  {name: 'Jim', age: 22, height: 175}
];
const sortedData = sortOn(data, ['age', 'height']);
console.log(sortedData);

Sort by nested properties

This feature allows you to sort an array of objects by nested properties. In this example, the array is sorted by the 'age' property within the 'details' object.

const sortOn = require('sort-on');
const data = [
  {name: 'John', details: {age: 25}},
  {name: 'Jane', details: {age: 22}},
  {name: 'Jim', details: {age: 30}}
];
const sortedData = sortOn(data, 'details.age');
console.log(sortedData);

Other packages similar to sort-on

lodash

Lodash is a popular utility library that provides a wide range of functions for manipulating arrays, objects, and other data structures. It includes a `_.sortBy` function that can be used to sort an array of objects by one or more properties. Compared to sort-on, Lodash offers a broader range of utilities but may be more complex to use for simple sorting tasks.

array-sort

The array-sort package provides a simple way to sort arrays of objects by one or more properties. It is similar to sort-on in terms of functionality but may have a different API and fewer features. It is a lightweight alternative for basic sorting needs.

sort-array

The sort-array package allows you to sort arrays of objects by one or more properties. It is similar to sort-on but offers additional customization options, such as specifying the sort order (ascending or descending) for each property. It is a good alternative if you need more control over the sorting process.

Sort an array on an object property

Install

$ npm install --save sort-on

Usage

const sortOn = require('sort-on');

// sort by an object property
sortOn([{x: 'b'}, {x: 'a'}, {x: 'c'}], 'x');
//=> [{x: 'a'}, {x: 'b'}, {x: 'c'}]

// sort descending by an object property
sortOn([{x: 'b'}, {x: 'a'}, {x: 'c'}], '-x');
//=> [{x: 'c'}, {x: 'b'}, {x: 'a'}]

// sort by a nested object property
sortOn([{x: {y: 'b'}}, {x: {y: 'a'}}], 'x.y');
//=> [{x: {y: 'a'}}, {x: {y: 'b'}}]

// sort descending by a nested object property
sortOn([{x: {y: 'b'}}, {x: {y: 'a'}}], '-x.y');
//=> [{x: {y: 'b'}, {x: {y: 'a'}}}]

// sort by the `x` propery, then `y`
sortOn([{x: 'c', y: 'c'}, {x: 'b', y: 'a'}, {x: 'b', y: 'b'}], ['x', 'y']);
//=> [{x: 'b', y: 'a'}, {x: 'b', y: 'b'}, {x: 'c', y: 'c'}]

// sort by the returned value
sortOn([{x: 'b'}, {x: 'a'}, {x: 'c'}], el => el.x);
//=> [{x: 'a'}, {x: 'b'}, {x: 'c'}]
