Open Exchange Rates module for nodeJS/npm

Important update: v0.2 is not backwards-compatible with v0.1, and the name has been changed from 'exchange-rates' to 'open-exchange-rates', to reflect the fact that it is solely a wrapper for the OXR service (the previous module had the rarely-used feature of being able to work with any other APIs, via a custom parse method).

Introduction

$ npm install open-exchange-rates

A nodeJS module that loads up-to-date currency/exchange rate data from the Open Exchange Rates API service, for use in your nodeJS scripts and apps.

Works perfectly with money.js (npm install money) - a tiny currency-conversion library for nodeJS (and web) - but you can use the data however you like.

NB: an App ID is required to connect to the API. It's free for personal/small-scale use and a bargain for business/commercial. Get yours in 30 seconds or less at openexchangerates.org/signup.

Requires: http-agent

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

Example Usage:

See the example.js in this repository for a basic, working usage example.

Start with this:

var oxr = require('open-exchange-rates');

Load latest rates from openexchangerates.org:

var oxr = require('open-exchange-rates');
oxr.set({ app_id: 'YOUR_APP_ID' })

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

Get historical rates:

var oxr = require('open-exchange-rates');
oxr.set({ app_id: 'YOUR_APP_ID' })

oxr.historical('2004-02-16', function() {
    // You can now use `oxr.rates`, `oxr.base` and `oxr.timestamp`...
});

Currency conversion with money.js (fx) module:

var oxr = require('open-exchange-rates'),
    fx = require('money');

oxr.set({ app_id: 'YOUR_APP_ID' })

oxr.latest(function() {
    // Apply exchange rates and base rate to `fx` library object:
    fx.rates = oxr.rates;
    fx.base = oxr.base;
    
    // money.js is all set up now:
    fx(100).from('HKD').to('GBP'); // 8.0424 or etc.
});

Advanced API Features:

The Open Exchange Rates API features several advanced features, for paying clients. These will be added to the module (and documented here) soon!
