Simplify Common Vue.js Computed Properties with vue-computed-helpers

Computed Properties in Vue are an amazing innovation that really cut down on development time. Some of the most common uses for them are “local reducers” for some data structure. (For example, to pull a particular element out of an array, or find the length of it, or count the number of elements and so on.) While the code for this isn’t particularly complex, it’s also something rather annoying to have to write all the time. vue-computed-helpers takes care of a number of these use-cases with a set of simple one-liners.


Install vue-computed-helpers in your Vue.js project.

If you’re using Yarn:

  1. yarn add vue-computed-helpers

With NPM:

  1. npm install vue-computed-helpers --save


vue-computed-helpers provides a number of simple helper methods, documented below, which can be used to create automatically-updated bindings in your templates.

For example:

  <div class="alligator-information">
    <p>There are {{numberOfHappy}} happy alligators.</p>
    <div v-for="alligator of alligators">
      <p>Name: {{alligator.name}}</p>
      <p>Weight: {{alligator.weight}}</p>

import { filter, count } from 'vue-computed-helpers';

export default {
  data() {
    return {
      alligators: [
          name: "Betty",
          weight: 850,
          isHappy: true
          name: "Thompson",
          weight: 792,
          isHappy: false
          name: "Hubert",
          weight: 927,
          isHappy: true

  computed: {
    happyAlligators: filter('alligators', 'isHappy', true),
    // It's easy to build chains!
    numberOfHappy: count(happyAlligators)

For the full list of available helpers, see the main repository.

Most likely most of your use-cases can be handled by built-in JS array functions, but a few of these might prove useful to you. Enjoy!
