There are plenty of currency converter packages out there, each getting their conversion rates from different places. Money Converter looks at multiple sources to ensure that you always have the most accurate exchange rate avaialable. Its fast, simple, light weight and most importantly, fault resistant.
npm install money-converter
To make sure that money-converter is as fast as possible, you pass it in an array of currencies and a bse currency. money-converter will then load the conversion rate between your base currency and each of the other currencies. This async process must be completed before the module can be used
we're going to be using the popular async
module here for demonstation of how load the currencies before using them
make sure to include the base currency in the list of currencies you pass into the constructor
var MoneyConverter = require('monver-converter');
var async = require('async');
var money;
async.series([
// load and cache currency conversions
// the base currency is USD
function(done) {
money = new MoneyConverter('USD', ['CAD', 'GBP', 'EUR', 'USD'], done)
}
// example of how we want to actually use it
function(done) {
money.convert(1000, {from: 'USD', to: 'EUR'});
// => 914
money.convert(10, {from: 'CAD', to: 'EUR'});
// => 6.655501347120076
money.convert(1, {from: 'GBP', to: 'USD'});
// => 1.50534397109739
done();
}
