Now that we have discussed the benefits of using this tool in detail in the earlier section, many of you might be wondering how this tool works, and how you trust it. For this reason, let us understand what exactly a currency convertor is and how it works. Currency convertor: A currency convertor is a handy tool available online to help you convert a value in one currency to the corresponding value in another currency. As discussed earlier, modernized software is used to make speedy and accurate conversions. But, the question still remains, how does it work? For this purpose, let us understand what the exchange rate is, and how it impacts currency conversions. Exchange rate: In simple words, the exchange rate is the current value of a currency with respect to another currency. Alternatively, we can say that the exchange rate is the rate at which one currency can be exchanged for another currency. For instance, the current exchange rate of Euro to US Dollar as noted on the 30th of May 2024 is 1.08. It implies that it will cost you 1.08 US Dollars to buy 1 Euro. The role of online currency convertor: The exchange rates for different currencies are different, and they constantly fluctuate due to the domestic currency value as well as the foreign currency value. It is challenging to keep a tab on the fluctuating exchange rates for various currencies and do rapid calculations. Online currency convertors track these rapid exchange rate fluctuations incessantly and fetch them for calculation purposes. The quicker a convertor fetches this information, the more reliable its currency conversion calculations. In this article, we’ll create a dynamic currency converter in React. We’ll start with a basic converter similar to Google’s online currency converter that gets exchange rates from an API. Then, we’ll improve it using the react-currency-input-field library for better input formatting. Finally, we’ll apply input masking to help ensure users enter values precisely in the required format.

Then, we’ll set up a React app that will fetch data from the API and store it. Setting up the API To create the currency converter, we first need to get the most recent exchange rates. For this, we’ll use the free Exchange-Rate API which provides exchange rates for any currency. We simply specify the currency in the API URL and then fetch the rates using a standard fetch request. First, create an API key from the Exchange-Rate API, then replace YOUR_KEY in the URL below with your actual key: https://v6.exchangerate-api.com/v6/YOUR_KEY/latest/USD As you can see in the URL above, the last three characters specify the currency for which exchange rates are requested. In this case, USD. In our converter, we will obtain this information from the user input. The JSON response will look something like this:
