# vue2-filters [](https://app.travis-ci.com/freearhey/vue2-filters)
A collection Vue.js filters.
## Installation
### Direct include
Simply include `vue2-filters` after Vue and it will install itself automatically:
```html
```
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:
```html
new Vue({
...
mixins: [Vue2Filters.mixin],
...
})
```
### CDN [](https://www.jsdelivr.com/package/npm/vue2-filters)
```html
```
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:
```html
new Vue({
...
mixins: [Vue2Filters.mixin],
...
})
```
### NPM [](https://www.npmjs.com/package/vue2-filters)
```
npm install vue2-filters
```
When used with a module system, you must explicitly install the filters via `Vue.use()`:
```js
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:
```js
import Vue2Filters from 'vue2-filters'
export default {
...
mixins: [Vue2Filters.mixin],
...
}
```
### Nuxt.js
```
npm install vue2-filters
```
When create file `plugins/vue2-filters.js`:
```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`:
```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:
```js
import Vue2Filters from 'vue2-filters'
export default {
...
mixins: [Vue2Filters.mixin],
...
}
```

## Global Configuration
If you need to override filter options globally you can do so by passing an object into `Vue.use()` function as the second argument:
```js
import Vue from 'vue'
import Vue2Filters from 'vue2-filters'
var Vue2FiltersConfig = {
capitalize: {
onlyFirstLetter: false
},
number: {
format: '0',
thousandsSeparator: ',',
decimalSeparator: '.'
},
bytes: {
decimalDigits: 2
},
percent: {
decimalDigits: 2,
multiplier: 100,
decimalSeparator: '.'
},
currency: {
symbol: '$',
decimalDigits: 2,
thousandsSeparator: ',',
decimalSeparator: '.',
symbolOnLeft: true,
spaceBetweenAmountAndSymbol: false,
showPlusSign: false
},
pluralize: {
includeNumber: false
},
ordinal: {
includeNumber: false
}
}
Vue.use(Vue2Filters, Vue2FiltersConfig)
```
## Programmatic Usage
Aside from using filters inside templates you can do this programmatically using default filters object:
```js
this.$options.filters.filterName(value)
```
For example, here's how you can use the `currency`filter:
```js
this.$options.filters.currency(100) // => $100.00
```
As for such filters as `limitBy`, `filterBy`, `find`, or `orderBy`, they can be used as usual methods:
```js
this.limitBy([1,2,3,4,5], 2) // => [1,2]
```
## Upgrade Guide
### Upgrade to 0.6.0 from 0.5.*
#### The `pluralize` filter
The `pluralize` filter arguments order has been changed. In the new version to specify several variants of words you can do this by passing an array as first argument, like so:
```js
{{ count | pluralize(['item', 'items']) }}
````
In addition, the function of translate a regular number to its ordinal representation was removed from the `pluralize` filter. Now there is a separate `ordinal` filter for this:
```js
{{ count | ordinal }}
```
### 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:
```js
{{ msg | capitalize({ onlyFirstLetter: true }) }}
```
### 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`):
```js
export default {
...
mixins: [Vue2Filters.mixin],
...
}
```
