This repository is a currency converter web application, letting people check and convert exchange rates between different currencies in real time. It is built with React for the interface and Vite as the tool that bundles and runs the project during development. The app pulls live exchange rates from the Frankfurter API, a free service that does not require signing up for an API key, so setting it up does not involve managing secret credentials. Users can pick two currencies, enter an amount, and see the converted value update automatically. A dedicated swap button, shown with a short animation, lets someone quickly flip which currency is being converted from and which is being converted to. Visually, the app uses a dark mode design with a glassmorphism look, meaning translucent, blurred panels are layered over the background for a frosted glass effect. The layout is fully responsive, so it works on desktop screens, tablets, and phones without needing separate versions. Under the hood, the project handles the practical parts of talking to an external API: it shows loading indicators while data is being fetched, handles errors if the exchange rate service is unavailable, and debounces API calls, which means it waits briefly after a user stops typing before sending a request, avoiding a flood of unnecessary network calls. State management inside the app uses React's useReducer hook, organized into a modular component structure so different pieces of the interface, like the input fields, currency selectors, and result display, are kept separate and easier to maintain. To run the project locally, a developer needs Node.js version 16 or higher along with npm or yarn, then can clone the repository and install dependencies through the usual setup steps. This is a small, focused, single purpose tool aimed at anyone who wants to compare currency values, rather than a large platform or library meant to be built into other software.
