A small library to convert currencies according to the EZB exchange rates.

npm install @divvit/currency-converter --save

Usage

  var converter = require('@divvit/currency-converter')();
  // if you want to change the storage path, call the script like that:
  // var converter = require('@divvit/currency-converter')({ storageDir: '/some/other/path' });
  // the default path is process.env.TMPDIR

  var moment = require('moment');

  var eurValue = 10;
  var conversionDate = moment('2015-01-01');
  converter.convert(eurValue, conversionDate, 'EUR', 'USD', function(err, usdResult) {
    if (err)
      return callback(err);

    console.log('Converted ' + eurValue + ' EUR to ' + usdResult.value + ' USD, according to FX rate of ' . usdResult.usedDate.format('DD.MM.YYYY') );

Important Notes:

If the queried day exists in the cache then the library uses the queried day for conversion.
If the queried day does not exit the library will try to use the nearst day before.
