vue2-filters Build Status

The list of standard filters Vue.js 1.* adapted for use in Vue.js 2.*

Installation

Direct include

Simply include vue2-filters after Vue and it will install itself automatically:

<script src="vue.js"></script>
<script src="vue2-filters.min.js"></script>

To use one of the predefined methods (such as limitBy, filterBy, find, or orderBy) in your component, you also need to add Vue2Filters.mixin to mixin list:

<script>
  new Vue({
    ...
    mixins: [Vue2Filters.mixin],
    ...
  })
</script>

CDN jsDelivr Hits

<script src="https://unpkg.com/vue/dist/vue.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/vue2-filters/dist/vue2-filters.min.js"></script>

To use one of the predefined methods (such as limitBy, filterBy, find, or orderBy) in your component, you also need to add Vue2Filters.mixin to mixin list:

<script>
  new Vue({
    ...
    mixins: [Vue2Filters.mixin],
    ...
  })
</script>

NPM npm

npm install vue2-filters

When used with a module system, you must explicitly install the filters via Vue.use():

import Vue from 'vue'
import Vue2Filters from 'vue2-filters'

Vue.use(Vue2Filters)

You don't need to do this when using global script tags.

To use one of the predefined methods (such as limitBy, filterBy, find, or orderBy) in your component, you also need to add Vue2Filters.mixin to mixin list:

import Vue2Filters from 'vue2-filters'

export default {
  ...
  mixins: [Vue2Filters.mixin],
  ...
}

Nuxt.js

npm install vue2-filters

When create file plugins/vue2-filters.js:

import Vue from 'vue'
import Vue2Filters from 'vue2-filters'

Vue.use(Vue2Filters)

Then, add the file inside the plugins key of nuxt.config.js:

module.exports = {
  //...
  plugins: [
    '~/plugins/vue2-filters'
  ],
  //...
}

To use one of the predefined methods (such as limitBy, filterBy, find, or orderBy) in your component, you also need to add Vue2Filters.mixin to mixin list:

import Vue2Filters from 'vue2-filters'

export default {
  ...
  mixins: [Vue2Filters.mixin],
  ...
}

  • Arguments:

    • {Number} [length] - default: 15
  • Example:

    {{ msg | truncate(10) }} // 'lorem ipsum dolor' => 'lorem ipsu...'

currency

  • Arguments:

    • {String} [symbol] - default: '$'
    • {Number} [decimalDigits] - default: 2
    • {Object} [options] - default: {}
  • Options:

    • {String} [thousandsSeparator] - default: ','
    • {String} [decimalSeparator] - default: '.'
    • {Boolean} [symbolOnLeft] - default: true
    • {Boolean} [spaceBetweenAmountAndSymbol] - default: false

    Use a different number decimal places:

    {{ amount | currency('', 0) }} // 12345 => ₽12,345

    Use a different thousands separator:

    {{ amount | currency('$', 0, { thousandsSeparator: '.' }) }} // 12345 => $12.345

    Use a different decimal separator:

    {{ amount | currency('$', 2, { decimalSeparator: ',' }) }} // 12345 => $12,345,00

    Use symbol on right:

    {{ amount | currency('$', 0, { symbolOnLeft: false }) }} // 12345 => 12,345$

Upgrade Guide

Upgrade to 0.4.0 from 0.3.*

In the new version it was decided to refuse from global registration of mixins, as it could lead to errors when using this package with other packages. Therefore, you need to manually add Vue2Filters.mixin into the mixin list of your components if you use at least one of the predefined methods (such as limitBy, filterBy, find or orderBy):

export default {
  ...
  mixins: [Vue2Filters.mixin],
  ...
}

You can read more about the reasons for this change here

Upgrade to 0.5.0 from 0.4.*

The capitalize filter

To match the definition of the word "capitalize", the default filter behavior has been changed. The filter now capitalizes the first letter in each word in the sentence (like CSS property text-transform).

If you want capitalize only first letter of sentence, you just need to add the onlyFirstLetter parameter to the filter, like so:

{{ msg | capitalize({ onlyFirstLetter: true }) }}
