Description

This module will return the exchange rate between a currency and SEK (Swedish Kronor) or the other way around, from SEK to a currency, using the 'Sveriges Riksbanks API'.

Install

Install with npm:

npm install swea-exchange-rate

How to use

In this example the cross rate between EUR (€ Euro) and SEK (Svenska kronor) is returned.

var exchangeRates = require('swea-exchange-rate');
exchangeRates.getExchangeRate( 'EUR', 'SEK', '2016-02-29', ( err, exchangeRate ) => {

  if (err) {
    // TODO: Handle error
  }
  
  console.log( `Rate: ${exchangeRate.value}`);
});
  

The response of the result in the callback method will be something like:

 {
   description: '1 EUR = ? SEK',
   date: '2016-02-29',
   value: '9.3936'
 }

If the specified date is a bank holiday, sunday or saturday, then no exchange rate will be available and in that case the most recent date with an exchange rate will be returned.
