Mastering Number Formatting in VueJS

Question

Mastering Number Formatting in VueJS

While working with VueJS, I encountered difficulties in formatting numbers the way I wanted. After exploring options like the builtin currency filter and vue-numeric, I realized they required modifications to achieve the desired look. Furthermore, these solutions were not suitable for displaying iterated array members.

I aimed to implement a format that could transform 12345.59 into:

12,345.59

OR

12.345,59

OR

12 345.59

This needed to work consistently across different computer/browser locales.

Answer №1

Get started by installing numeral.js:

npm install numeral --save

Create a unique custom filter:

<script>
  var numeral = require("numeral");

  Vue.filter("formatNumberCustom", function (value) {
    return numeral(value).format("0,0"); // you can customize further using the documentation
  });

  export default
  {
    ...
  } 
</script>

Implement your new filter in your code:

<tr v-for="(item, key, index) in tableRows">
  <td>{{item.integerValue | formatNumberCustom}}</td>
</tr>

Using Intl.NumberFormat() in JavaScript:</p>

<pre><code>...
created: function() {
    let num = 9876543;
    console.log(new Intl.NumberFormat().format(num))
},
...

//output -> 9 876 543

Answer №3

There is a convenient built-in JavaScript function specifically designed for this task.

If you can confidently assume that the variable will always be a Number and not a "number String," you may use the following syntax:

{{ num.toLocaleString() }}

For added safety, consider using:

{{ Number(num).toLocaleString() }}

If you're looking for a simple solution, try the following:

<template>
  <div> {{ total | toUSD }} </div>
</template>

<script>
export default {
  data () {
    return {
      total: 123456
    }
  },

  filters: {
    toUSD (value) {
      return `$${value.toLocaleString()}`
    }
  }
}
</script>

For a more complex approach, you can use this code or the one below:

Add this in main.js

import {currency} from "@/currency";
Vue.filter('currency', currency)

Then include this in currency.js

const digitsRE = /(\d{3})(?=\d)/g

export function currency (value, currency, decimals) {
  value = parseFloat(value)
  if (!isFinite(value) || (!value && value !== 0)) return ''
  currency = currency != null ? currency : '$'
  decimals = decimals != null ? decimals : 2
  var stringified = Math.abs(value).toFixed(decimals)
  var _int = decimals
    ? stringified.slice(0, -1 - decimals)
    : stringified
  var i = _int.length % 3
  var head = i > 0
    ? (_int.slice(0, i) + (_int.length > 3 ? ',' : ''))
    : ''
  var _float = decimals
    ? stringified.slice(-1 - decimals)
    : ''
  var sign = value < 0 ? '-' : ''
  return sign + currency + head +
    _int.slice(i).replace(digitsRE, '$1,') +
    _float
}

Lastly, in your template:

<div v-for="item in items">
  {{item.price | currency}}
</div>

Vue 3 Update

In Vue 3, the use of filters has been deprecated. Instead, we can define global properties to handle such functionality:

app.config.globalProperties.$filters = {
    formatNumber(number) {
        return Intl.NumberFormat().format(number);
    }
}

To utilize this custom filter, you can do the following:

<h2>{{ $filters.formatNumber(amount) }}</h2>

Answer №6

Give this code a try for those using Vue.js 2

<template>
{{lowPrice | currency}}
</template>
<script>
data:(){
 return {lowPrice: 200}
}
filters:{
      currency(value) {
 return new Intl.NumberFormat("en-US",
 { style: "currency", currency: "USD" }).format(value);
 }
    }
</script>

Note: Vue.js 3 no longer supports filters, so you can implement this logic in computed properties

<template>
{{currency}}
</template>
<script>
data:(){
 return {lowPrice: 200}
}
computed:{
      currency() {
 return new Intl.NumberFormat("en-US",
 { style: "currency", currency: "USD" }).format(this.lowPrice);
 }
    }
</script>

I come from Chile and I have implemented a custom format, for instance: $50.000.000,56

install npm install numeral --save

import numeral from 'numeral'
// incorporating a locale
numeral.register('locale', 'cl', {
  delimiters: {
    thousands: '.',
    decimal: ','
  },
  abbreviations: {
    thousand: 'm',
    million: 'M',
    billion: 'B',
    trillion: 'T'
  },
  ordinal: function (number) {
    return number === 1 ? 'er' : 'ème'
  },
  currency: {
    symbol: '$'
  }
})

// changing between different locales
numeral.locale('cl')

Subsequently, include the custom format...

Vue.filter('formatNumberMoney', function (value) {
  return numeral(value).format('0,0.')
   // there are options to display other groupings/separators, refer to the documentation
})

Answer №9

To transform numbers like 12000 into 12,000, you can utilize the following Vue filter examples

Implement a global filter that is accessible throughout all components

Navigate to the file where your Vue instance is initialized, typically (main.js)
```
Vue.filter('format_number', function (value){
  return parseInt(value).toLocaleString()
})
```
To apply this in your Vue pages,
```
  {{ 12000 | format_number}}
```

If you prefer using it within a single Vue file, include the following code in your component options


filters: {
  format_number: function (value){
   return parseInt(value).toLocaleString()
  }
},

To implement in your Vue pages:

  {{ 12000 | format_number}}

For more information on filters, check out this documentation page

Keep in mind that Filters are not compatible with Vue 3x
