Requires a CoinMarketCap API key and npm install before the app can fetch live prices.

In plain English

This repository contains a simple web app called cryptocurrency-price that displays live cryptocurrency prices. You open it in your browser and see current market values pulled from the CoinMarketCap API, which is a well-known source for crypto pricing data. The project includes a live demo, so you can try it out without installing anything. The app is built with React, a popular tool for creating interactive web pages. At a high level, the app reaches out to CoinMarketCap's API each time it loads, grabs the latest prices, and displays them on screen. The README does not go into detail about which specific cryptocurrencies are shown or how often the prices refresh. This would appeal to someone just starting out with web development who wants a minimal example of how to connect a React app to an external data source. A beginner could use it as a learning reference, or a founder might keep it handy as a quick personal dashboard to check crypto prices without visiting a full exchange site. It is straightforward and does not try to do anything beyond showing prices. Much of the README is actually a walkthrough of how to deploy the app using Surge, a free service for hosting static websites. The author documents the process of building the project and publishing it to a custom URL ending in surge.sh. They also note a limitation of Surge: when you update the app, you have to re-upload the entire project rather than just pushing the changed files. This is worth knowing if you plan to deploy your own version or modify this one, since every update requires a full redeploy.
