Currency Converter Web App using HTML, CSS & JavaScript 💰
In this video, I built a simple Currency Converter web app using vanilla HTML, CSS, and JavaScript.
The main focus of this project was working with real-time external APIs, handling asynchronous requests properly, and converting dynamic financial data into a usable UI.
Instead of hardcoding exchange rates, the app fetches live data and performs the conversion instantly based on user input.
Features:
Convert any amount between selected currencies
Fetch real-time exchange rates from an external API
Clean and beginner-friendly interface
Simple conversion logic (intentionally no swap feature for clarity)
Tech Stack:
HTML – structure
CSS – clean UI styling
JavaScript (ES6+) – API calls and conversion logic
Free Currency API – real-time exchange rate data

This project helped me practice:
Working with fetch() and async/await
Parsing JSON API responses
Handling API keys securely (and understanding limitations in frontend-only apps)
Converting financial data accurately
This is part of my build-in-public journey, where I share real projects and practical development experience. If you're a developer trying to get better at API integration and real-world frontend logic, this series is for you.
