Angular Currency Format

 

This project is module for AngularJS. It provides:

- A service (factory) that retrieves currency information (name, symbol, fraction and formating) according to ISO 4217 currency codes
- A filter to print formatted currency (-100 USD -> -$100.00)

Installation

This library is available with the bower package manager, you can either:

- Execute the following command: bower install angular-currency-format

- Add 'currencyFormat' to your angular.module dependency, usually in app.js

``javascript
angular.module('myApp', ['currencyFormat']);
`

Usage

$3

In the factory there are two methods that return information about the currencies.

`javascript
// Declare the factory as dependency
angular.module('myApp')
.controller('MyCtrl', function (currencyFormatService) {
// Get the information about the currencies
console.log(currencyFormatService.getCurrencies());
// outputs:
// {
// 'AMD': {
// 'name': 'Armenian Dram',
// 'fractionSize': 2,
// 'symbol': {
// 'grapheme': 'դր.',
// 'template': '1 $',
// 'rtl': false
// },
// 'uniqSymbol': {
// 'grapheme': 'դր.',
// 'template': '1 $',
// 'rtl': false
// }
// },
// ...
// }

// Get the information about currency by ISO 4217 currency code
console.log(currencyFormatService.getByCode('EUR'));
// outputs:
// {
// 'name': 'Euro',
// 'fractionSize': 2,
// 'symbol': {
// 'grapheme': '€',
// 'template': '$1',
// 'rtl': false
// },
// 'uniqSymbol': {
// 'grapheme': '€',
// 'template': '$1',
// 'rtl': false
// }
// }

// Get the information about the delimiters
console.log(currencyFormatService.getLanguages());
// outputs:
// {
// 'ar_AE': {
// 'decimal': '.',
// 'thousands': ','
// },
// ...
// }

// Get the information about the delimiters by locale ID
console.log(currencyFormatService.getLanguageByCode('en_US'));
// outputs:
// {
// {
// 'en_US': {
// 'decimal': '.',
// 'thousands': ','
// }
// }
});
`

Information about currencies is an object which has the structure:

`javascript
{
'AMD': { // ISO 4217 currency code.
'name': 'Armenian Dram', // Currency name.
'fractionSize': 2, // Fraction size, a number of decimal places.
'symbol': { // Currency symbol information.
'grapheme': 'դր.', // Currency symbol.
'template': '1 $', // Template showing where the currency symbol should be located
// (before or after amount).
'rtl': false // Writing direction.
},
'uniqSymbol': { // Alternative currency symbol information. We recommend to use it
// when you want to exclude a repetition of symbols in different
// currencies.
'grapheme': 'դր.', // Alternative currency symbol.
'template': '1 $', // Template showing where the alternative currency symbol should be
// located (before or after amount).
'rtl': false // Writing direction.
}
},
...
}
`

Symbol/uniqSymbol field is null, when the currency has no symbol/alternative symbol.

Information about languages is an object which has the structure:

`javascript
{
"en_US": { // Locale ID
"decimal": ".", // Decimal delimiter
"thousands": "," // Thousands delimiter
},
...
}
`

$3

Instead of directly using the currency symbol, you only need the 3 char long currency code (e.g. USD or JPY).
It will take the right symbol, format and fraction size. The fraction can be set up by providing a number of decimal places after the currency field:

`javascript
// in controller
$scope.amount = -1234.56;
$scope.isoCode = 'USD';
$rootScope.currencyLanguage = 'en_US'; // Can be set through the parameter of the filter. Default 'en_US'.

// in template
{{ amount | currencyFormat:isoCode }} // -$1,234.56
{{ amount | currencyFormat:isoCode:0 }} // -$1,235
{{ amount | currencyFormat:'RUR':null:true:'ru_RU' }} // -1 234,56 ₽
`

If there is no currency symbol, then the filter will return the value in the following format: formated amount + ISO code. For example -1,234.56 USD`.
