This project is bootstraped with Create React App. It is unopinionated with only web3.js as an added dependency, so nothing stands in your way.
Run npm start to start the dev server.
See all available scripts.
The installed version of react-scripts is 4.x instead of the latest 5.x, which uses Webpack 5. This is because Webpack 5 no longer auto-polyfills Node.js core modules, which web3.js depends on.
If you don't want to use react-scripts at 4.x, alternative solutions include eject and react-app-rewired (See instruction).
