Creating a simple cryptocurrency converter using Strapi as the backend and Svelte as the frontend involves several steps, including creating a new Strapi project, setting up the API and controller to handle requests, and building the front-end interface using Svelte. The process requires understanding of Node.js, React, and JavaScript, as well as familiarity with Strapi's collection types, routes, and controllers. Additionally, it involves installing dependencies like Axios for making HTTP calls to external APIs. The cryptocurrency converter application can be used to convert between different cryptocurrencies, such as Bitcoin (BTC) and Ethereum (ETH), using real-time exchange rates provided by an external API. By following this tutorial, developers can create a working crypto converter that meets their needs.
