Combine a series of sort functions to create complex sort orders

Package Exports

  • sort-order
  • sort-order/build/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (sort-order) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

npm package npm downloads main branch status

Combine a series of sort functions to create complex sort orders.

Install

npm install --save sort-order

Example

Sort an array of objects by creator first, then joinTime and finally id:

import sortBy from 'sort-order';

// Items to order
const a = { creator: true, joinTime: 0, id: 987 };
const b = { creator: false, joinTime: 1, id: 123 };
const c = { creator: false, joinTime: 1, id: 456 };
const d = { creator: false, joinTime: 2, id: 789 };

// Individual sort functions
const creator = (a, b) => (a.creator && -1) || (b.creator && 1) || 0;
const field = (field) => (a, b) => a[field] - b[field];

// Combined sort function
const ordering = sortBy(creator, field('joinTime'), field('id'));

// Sort!
[d, c, b, a].sort(ordering); // [a, b, c, d]
