Modern alternatives to the sort-object package for sorting object keys

Replacements for sort-object

Object.entries and Array.sort (native)

For simple cases:

import sortObj from 'sort-object' // [!code --]

const sorted = sortObj(object) // [!code --]

// Ascending A→Z
const sorted = Object.fromEntries( // [!code ++]
  Object.entries(object).sort((a, b) => a[0].localeCompare(b[0])) // [!code ++]
) // [!code ++]

Replicating sortBy (function returns an ordered key list):

import sortObj from 'sort-object' // [!code --]

const sorted = sortObj(object, { // [!code --]
  sortBy: (obj) => { // [!code --]
    const arr = [] // [!code --]
    Object.keys(obj).forEach((k) => { // [!code --]
      if (obj[k].startsWith('a')) // [!code --]
        arr.push(k) // [!code --]
    }) // [!code --]
    return arr.reverse() // [!code --]
  } // [!code --]
}) // [!code --]

const sortBy = (obj) => // [!code ++]
  Object.keys(obj) // [!code ++]
    .filter((k) => obj[k].startsWith('a')) // [!code ++]
    .reverse() // [!code ++]
const sorted = Object.fromEntries( // [!code ++]
  sortBy(object).map((k) => [k, object[k]]) // [!code ++]
) // [!code ++]

sort-object-keys

sort-object-keys is zero‑dependency and matches common sort-object use cases (custom order array or comparator).

import sortObj from 'sort-object' // [!code --]
import sortObjectKeys from 'sort-object-keys' // [!code ++]

// Default A→Z
const sorted = sortObj(object) // [!code --]
const sorted = sortObjectKeys(object) // [!code ++]

// With comparator
const sortedByCmp = sortObj(object, { sort: (a, b) => a.localeCompare(b) }) // [!code --]
const sortedByCmp = sortObjectKeys(object, (a, b) => a.localeCompare(b)) // [!code ++]

sortobject

sortobject is zero‑dependency and deeply sorts nested objects.

import sortObj from 'sort-object' // [!code --]
import sortobject from 'sortobject' // [!code ++]

const sorted = sortObj(object) // [!code --]
const sorted = sortobject(object) // [!code ++]
