Package Exports

sort-object-keys

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-object-keys) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Sort Object

Returns a copy of an object with all keys sorted.

The second argument is optional and is used for ordering - to provide custom sorts. You can either pass an array containing ordered keys or a function to sort the keys (same signature as in Array.prototype.sort()).

const assert = require('assert');
const sortObject = require('sort-object-keys');

assert.equal(JSON.stringify({
  c: 1,
  b: 1,
  d: 1,
  a: 1,
}), JSON.stringify({
  a: 1,
  b: 1,
  c: 1,
  d: 1,
}));

assert.equal(JSON.stringify(sortObject({
  c: 1,
  b: 1,
  d: 1,
  a: 1,
}, ['b', 'a', 'd', 'c'])), JSON.stringify({
  b: 1,
  a: 1,
  d: 1,
  c: 1,
}));

function removeKeyAncCompareIndex(keyA, keyB){
  var a = parseInt(keyA.slice(4));
  var b = parseInt(keyB.slice(4));
  return a - b;
}

assert.equal(JSON.stringify(sortObject({
  "key-1": 1,
  "key-3": 1,
  "key-10": 1,
  "key-2": 1,
}, removeKeyAncCompareIndex)), JSON.stringify({
  "key-1": 1,
  "key-2": 1,
  "key-3": 1,
  "key-10": 1,
}));
