You can install this module by using npm NPM:

npm install ecb-exchange-rates

# Usage

The first step is to include the library on you app by doing:

var currencyConverter = require('ecb-exchange-rates');

If we need to convert a given value, then we create this settings object:

var settings = {};
settings.fromCurrency = "GBP";
settings.toCurrency = "USD";
settings.amount = 90;
settings.accuracy = 10;

After that, we can call to the convert function in this way:

currencyConverter.convert(settings , function(data){
  console.log(JSON.stringify(data));
});

The data object that you will receive on the callback, will contain:

currency
exchange Rate
amount

By instance: {"currency":"USD","exchangeRate":1.64686,"amount":148.21739}

Another User Case will be if we only need the exchange rate, then:

var settings = {};
settings.fromCurrency = "GBP";
settings.toCurrency = "USD";
settings.accuracy = 10;

After that, we can call to the getExchangeRate function in this way:

currencyConverter.getExchangeRate(settings , function(data){
  console.log(JSON.stringify(data));
});

The data object that you will receive on the callback, will contain:

toCurrency
fromCurrency
exchangeRate

By instance: {"toCurrency":"USD","fromCurrency":"GBP","exchangeRate":1.64686}

In case we only need all the supported currencies with their exchange rates, we can call:

currencyConverter.getAllCurrencies(function(data){
  console.log(JSON.stringify(data));
});

And it will return something like this (with the EUR as base):

[{"currency":"USD","rate":"1.3151"},{"currency":"JPY","rate":"138.11"},{"currency":"BGN","rate":"1.9558"},{"currency":"CZK","rate":"27.658"},{"currency":"DKK","rate":"7.4476"},{"currency":"GBP","rate":"0.79855"},{"currency":"HUF","rate":"314.02"},{"currency":"LTL","rate":"3.4528"},{"currency":"PLN","rate":"4.1905"},{"currency":"RON","rate":"4.4043"},{"currency":"SEK","rate":"9.1969"},{"currency":"CHF","rate":"1.2078"},{"currency":"NOK","rate":"8.1605"},{"currency":"HRK","rate":"7.6210"},{"currency":"RUB","rate":"48.4385"},{"currency":"TRY","rate":"2.8427"},{"currency":"AUD","rate":"1.4094"},{"currency":"BRL","rate":"2.9397"},{"currency":"CAD","rate":"1.4336"},{"currency":"CNY","rate":"8.0772"},{"currency":"HKD","rate":"10.1923"},{"currency":"IDR","rate":"15472.66"},{"currency":"ILS","rate":"4.7154"},{"currency":"INR","rate":"79.4518"},{"currency":"KRW","rate":"1341.18"},{"currency":"MXN","rate":"17.2022"},{"currency":"MYR","rate":"4.1844"},{"currency":"NZD","rate":"1.5802"},{"currency":"PHP","rate":"57.395"},{"currency":"SGD","rate":"1.6469"},{"currency":"THB","rate":"42.140"},{"currency":"ZAR","rate":"14.0505"}]

Sometimes we need to display amounts accordingly with the currency, in that case we can call:

currencyConverter.getCurrenciesMetadata(function(data){
  console.log(JSON.stringify(data));
});

(You can also filter the result by passing a single currency as parameter)

And it will return all the needed data for visualisation such as:
