The first time you run this app, make sure to run npm install first, to install needed dependencies. Then, to run the app and see it in your browser, you can run
npm run dev
This will run the app using Vite's development server. You should be able to visit the running app by viewing http://localhost:5173 to view the app in your browser. The development server is set up to use "Hot Module Replacement" (HMR), so the app will automatically reload in your browser if you make edits to the code.
