Simple Open Exchange Rates

Extremely simple way to convert rates between currencies using rates at OpenExchangeRates.org.

Pulls the exchange rate remotely and saves locally to a text file.

Getting Started

Register for a client key at OpenExchangeRates.org

Install the package:

npm install currency-converter

Use it:

var cc = require('currency-converter')({
  CLIENTKEY: YOUR_OPEN_EXCHANGE_RATES_KEY, [fetchInterval: 3600000]
});

NOTE: Default fetchInterval value is set to one hour.

Usage

This module makes it extremely easy for you to convert currencies.

The very basic input takes in two parameters. convertFrom & convertTo must be valid country codes. See list here.

The module fetches live rates on initialize, saves it locally, and retrieves locally saved rates by default, unless otherwise specified.

.convert(amount, convertFrom, convertTo, [live])

Converts an amount specified to a specific currency. live is an optional parameter that uses live rates from openexchangerates.org

Response:

const converted = await cc.rates(1, 'USD', 'EUR');
// {
//    "currency": "EUR",
//    "symbol": "€",
//    "amount": 0.76
// }

.rates(convertFrom, convertTo, [live])

Returns the conversion rate between two currencies:

const rate = await cc.rates('USD', 'EUR');
// 0.76

Fetch the live rate:

const rate = await cc.rates('USD', 'EUR', true);
// 0.76

.currencies

The map of currency codes to info about the currency

cc.currencies.EUR
// {
//    "currency": "EUR",
//    "symbol": "€",
//    "amount": 0.76
// }

.shutdown

Stop the periodic polling for rates.

cc.shutdown();

If you don't do this, your script will never terminate normally since there will be a dangling timeout.
