Nodejs utility to consult the rate exchange (Us Dollar / Euro -> Colon) from The Central Bank of Costa Rica
$ npm install exchangecr --save
import { UsDollar, Euro } from 'exchangecr'
const dollar = new UsDollar()
await dollar.exchange() // { date: '00/00/0000', purchaseRate: 000.00, saleRate: 000.00 }
const euro = new Euro()
await euro.exchange() // { date: '00/00/0000', rate: 000.00 }The exchange methods support range of dates (should be in EU format DD/MM/YYYY), one date or even no date.
If there is no params exchange returns the exchange of today
await dollar.exchange()
// { date: '00/00/0000', purchaseRate: 000.00, saleRate: 000.00 }If there is one date exchange returns a exchange object
await dollar.exchange('25/12/2018')
// { date: '25/12/2018', purchaseRate: 000.00, saleRate: 000.00 }If there is a range of dates exchange returns a exchange array
await dollar.exchange('25/12/2018', '26/12/2018')
// [
// { date: '25/12/2018', purchaseRate: 000.00, saleRate: 000.00 },
// { date: '26/12/2018', purchaseRate: 000.00, saleRate: 000.00 }
// ]For euro there is only one rate (no purchase and sale rates). Usually with poor support from the bank for updates dates, works fine with 3 days of delay
await euro.exchange('25/12/2018', '26/12/2018')
// [
// { date: '25/12/2018', rate: 000.00 },
// { date: '26/12/2018', rate: 000.00 }
