vue-computed-helpers

This package contains a bunch of useful helpers that can be used to simplify computed properties. Instead of creating your own filters use these helpers to get a sum, check if an array is empty, or countBy a key of an object.

Helpers

There are currently 22 Computed helpers for Vue apps to use with computed properties, the full list is available here .

Where x means that it can be either value or property name. If you provide a string and there will be a property with that name it's value will be used to perform the check.

Example

To start working with the computed-helpers use the following commands to install it.

Via npm:

npm install vue-computed-helpers --save

Via yarn:

yarn add vue-computed-helpers

Import the helpers you are going to need in your project

import { empty, count } from 'vue-computed-helpers'

Usage:

export default { data() { return { dimmerVariations: ['', 'inverted'], modalVariations: ['', 'fullscreen', 'basic', 'small', 'large'], } }, computed: { modalVariationsCount: count('modalVariations'), checkEmptyArray: empty('dimmerVariations') } }

You could just display the results in the template

<h4> <p> {{modalVariationsCount}}properties</p> <p>Is the array empty? {{checkEmptyArray}}</p> </h4>
