Making Money Moves - Building a Real-Time Currency Converter with Django 🤑

Show Me the Money: Introduction#

Ever wondered how to keep track of your money across different currencies? I’ve created a sleek Django application that does just that! Using the ExchangeRates API, this converter brings you real-time currency conversion capabilities with just a few lines of code.

Change for the Better: Technical Overview#

The application consists of three main components:

1. The Money Pit: Backend Structure#

# views.py highlights
def currency_convert(request):
    form = CurrencyConversionForm(request.POST or None)
    if form.is_valid():
        # Fetch real-time rates from ExchangeRates API
        endpoint = f'https://api.exchangeratesapi.io/v1/latest?access_key={API_KEY}&symbols={from_currency},{to_currency}'

The view handles API communication and calculations, using environment variables for secure API key storage. Currency Converter
