@abstractapi/javascript-exchange-rates v1.0.0

AbstractAPI javascript-exchange-rates library

Integrate the powerful Exchange Rates API from Abstract in your Javascript or NodeJS project in a few lines of code.

The Exchange Rate API is an REST API that allows you to:

• look up the latest exchange rates for 80+ currencies via the live endpoint
• get historical exchange rates using the historical endpoint
• convert an arbitrary amount from one currency to another using the convert endpoint

It's very simple to use: you only need to submit your API key and a currency symbole (such as "USD"), and the API will respond with current exchange rate, historical data, or convertion rates.

Quickstart

AbstractAPI javascript-exchange-rates library returns a Promise so you can use one of the following approaches:

Async/Await

async function getLiveRates(currency) {
  let response = await AbstractExchangeRates.live(currency);
  console.log(response);
}

async function getHistoricalRates(currency, date) {
  let response = await AbstractExchangeRates.historical(currency, date);
  console.log(response);
}

async function getConvertion(currency, target) {
  let response = await AbstractExchangeRates.convert(currency, target);
  console.log(response);
}

Using .then()

function getLiveRates(currency) {
  AbstractExchangeRates.live(currency)
    .then(response => {
      console.log(response);
    })
}

function getHistoricalRates(currency, date) {
  AbstractExchangeRates.historical(currency, date)
    .then(response => {
      console.log(response);
    })
}

function getConvertion(currency, target) {
  AbstractExchangeRates.convert(currency, target)
    .then(response => {
      console.log(response);
    })
}
