Currency Converter

This is a simple web application to convert between a limited number of currencies basing on exchange rates from the Czech National Bank (Česká národní banka, ČNB).

The application is built with React and TypeScript. Vite create app template was used to start it.

To run the application locally, clone the repository and run:

npm install
npm run dev

At the moment there is no API on the back end to get ČNB exchange rates and return them to the front end. The direct request from React app to the ČNB API is blocked by the CORS policy, so the proxy capabilities (redirects/rewrites) are used:

• on local environment in Vite server (see vite.config.ts),
• on Vercel (see vercel.json),
• on Netlify (see _redirects in public folder).

TODO

• Load currency exchange rates from the ČNB API only once a (working) day at 2pm CET.
