Getting Started: Integrating Real-Time Currency Conversion
Let’s delve into how effortlessly you can integrate real-time currency conversion into your Node.js application with our wrapper. After a simple setup process, you’ll have access to various endpoints, each catering to different aspects of currency data.
Helpful info before we get started:
- If you have not signed up already, head to our currency api homepage to create a free or paid account.
- Login and grab your API key from the account area.
- Quickly browser our API documentation to familiarise yourself with our API
- Load up your NodeJs application or create a brand new .js file.
Let’s get started!
Install the NPM package
npm install currencyapi-node
Live Rates
Retrieving the most current currency rates is a function that many global services depend on. Here’s how you can obtain these live rates:
const CurrencyApi = require('currencyapi-node');
const currency = new CurrencyApi('YOUR_API_KEY');
// Fetching the live rates
currency
.rates()
.get()
.then(response => {
console.log(response);
// Sample response
// {
// "valid": true,
// "updated": 1526293289,
// "base": "GBP",
// "rates": { ... }
// }
}).catch(error => {
console.error("An error occurred: ", error);
});
This endpoint returns a plethora of information, including the validity of the data, the last time it was updated, the base currency, and the actual rates themselves. The application can use these live rates for a variety of purposes, such as calculating transaction amounts in different currencies, displaying current rates, or even analysing the market situation.
Currency Conversion
Whether for shopping cart calculation, financial analysis, or online payment processing, direct currency conversion is a cornerstone utility. Here’s how you can perform on-the-fly currency conversion:
const CurrencyApi = require('currencyapi-node');
const currency = new CurrencyApi('YOUR_API_KEY');
// Converting 99.87 GBP to BTC
currency
.convert()
.from('GBP')
.to('BTC')
.amount(99.87)
.get()
.then(response => {
console.log(response);
// Sample response
// {
// "valid": true,
// "updated": 1527708277,
// "conversion": {
// "amount": 99.87,
// "from": "GBP",
// "to": "BTC",
// "result": 0.017462
// }
// }
}).catch(error => {
console.error("An error occurred: ", error);
}
);
The convert endpoint is direct and precise, giving you the exact value in the desired currency. This real-time conversion is crucial for transactions, especially in a world where digital currencies like Bitcoin reflect volatile prices.
Historical Rates
Sometimes, understanding the past is key to predicting the future, especially in finance. Retrieving historical currency rates is simple:
const CurrencyApi = require('currencyapi-node');
const currency = new CurrencyApi('YOUR_API_KEY');
// Fetching historical rates for a specific date
currency
.history()
.date('2010-12-25')
.get()
.then(response => {
console.log(response);
// Sample response
// {
// "valid": true,
// "updated": 1526293289,
// "base": "GBP",
// "date": "2010-12-25",
// "rates": { ... }
// }
}).catch(error => {
console.error("An error occurred: ", error);
}
);
This data is indispensable for market analysis, financial modeling, or investment planning, where insights into currency stability or inflation rates are crucial.
Timeframe-specific Rates
Monitoring currency fluctuations over a specific period can provide valuable insights. Here’s how you can extract this information:
const CurrencyApi = require('currencyapi-node');
const currency = new CurrencyApi('YOUR_API_KEY');
// Retrieving currency rates for a specific timeframe
currency
.timeframe()
.startDate('2017-12-25')
.endDate('2018-01-10')
.get()
.then(response => {
console.log(response);
// Sample response
// {
// "valid": true,
// "updated": 1526293289,
// "base": "GBP",
// "start_date": "2017-12-25",
// "end_date": "2018-01-10",
// "rates": { ... }
// }
}).catch(error => {
console.error("An error occurred: ", error);
}
);
Such temporal data is fundamental for trend analysis, helping businesses and individuals make informed decisions based on historical performance.
Available Currencies
Knowing what currencies are available for conversion is essential. This endpoint provides a list of all accessible currencies, along with their full names:
const CurrencyApi = require('currencyapi-node');
const currency = new CurrencyApi('YOUR_API_KEY');
// Fetching the list of available currencies
currency
.currencies()
.get()
.then(response => {
console.log(response);
// Sample response
// {
// "valid": true,
// "currencies": { ... }
// }
}).catch(error => {
console.error("An error occurred: ", error);
}
);
