Process of Building Real-Time Currency Converter App 

APIs are sets of protocols, routines, and tools for building software applications. APIs allow developers to access and use third-party application services and data. In this case, we will use free currency converter APIs to provide real-time currency conversion rates to our users. Here are some steps for creating a real-time App.  

Choosing the Right API 

The initial step in building a real-time currency data converter app is to select a reliable and accurate API. There are various APIs available on the market, but not every API gives you real-time data or supports multiple currencies. 

Designing the Frontend 

After selecting an API, the next step is to design the front end of your app. The front end is the user-facing part of an app and displays the user interface. It allows users to interact with the app. In order to design the front end, you’ll require to select a programming language and a framework. There are numerous options available, but we recommend using Javascript and React, Angular, and Vue.js,  as they are easy to learn and widely used. To get started: 

  • Create a new React app using the create-react-app command, and install the necessary dependencies, like Axios for API requests and Bootstrap for styling. 
  • Create a form that allows users to input the amount they want to convert currencies. 
  • Add a button that triggers an API request to get the exchange rate for the selected world currencies. 
  • Once API returns the exchange rate, calculate the converted amount and display it to the user. 

In addition, you can add features like a dropdown menu allowing users to select their preferred base currency or save conversion history. 

Forming the Backend 

After designing the front end, the next is to form a backend of the app. The backend makes API requests, processes data, and sends it back to the front end. To start the backend, you’ll need to select a server-side programming language and a framework. We recommend using Node.js and Express because they are easy to use and widely supported. 

  • Begin by creating a new Node.js project and installing the necessary dependencies, like Express and Axios. Next, form a way that handles currency conversion requests. 
  • When a user sends a currency conversion request, the route should make an API request to the selected API, passing the selected currencies and the amount to be converted.
  • Once the API returns the exchange rate, the route should compute the converted amount and send it back to the front end.
  • You can also include more features like caching the exchange rate to reduce API requests or implementing error handling to ensure the app handles unexpected errors gracefully.  

Deploying the App 

After completing the front-end and back-end development, the next step is to deploy the app to a web server. Many options are available for deploying web apps, but we recommend using PaaS(Platform-as-a-service) [1] provider, like Firebase [2] or Heroku [3].

Currency conversion is important for investors who want to invest in foreign stocks, bonds, or other assets denominated in a foreign currency. They need to be able to convert their home currency into the currency of the country where they want to invest.
