exchange-rates

Open Exchange Rates module for nodeJS/npm

$ npm install exchange-rates

A nodeJS module that loads up-to-date exchange rate data from the Open Exchange Rates API project (via openexchangerates.org/latest.json), or any other service you specify.

Features override-able validation/parsing of raw API data, so that you can use it to load data from any service and parse/format it according to needs.

Works great with money.js (npm install money) - a tiny currency-conversion library for nodeJS (and web).

Requires http-agent

To install, type npm install exchange-rates in the terminal. Then see below.

Example Usage:

Start with this:

var exchange = require("exchange-rates");

Default - load data from openexchangerates.org:

exchange.load(function() {
	// You can now use `exchange.rates`, `exchange.base` and `exchange.timestamp`
});

Usage with some other API:

// Custom callback function to parse the returned API data:
exchange.parse = function(data, exchange) {
	exchange.base = "USD";
	exchange.rates = parseJSON(data);
	return exchange;
};

// Load the API data:
exchange.load("http://mycoolwebservi.ce/api.json", function() {
	// You can now use `exchange.rates` and `exchange.base` as defined in `parse()`
});

// You can also set the URL globally, then just load as normal:
exchange.url = "http://mycoolwebservi.ce/api.json";

Usage with money.js:

var exchange = require("exchange-rates"),
	fx = require("money");

exchange.load(function() {
	// Apply exchange rates and base rate to `fx` object:
	fx.rates = exchange.rates;
	fx.base = exchange.base;
	
	// money.js is all set up:
	fx(1).from("GBP").to("USD"); // 1.586 or etc.
});
