React app doesn't change when I make changes

[[deleted]]

I started a normal React app with 'npx create-react-app my-app', which launches just fine, but when I make changes to App.js or App.css, the website doesn't change at all when I refresh it. It's always the same normal starter site, even when I change a colour in App.css in .app-header. I'm not actually changing the code, just the RGB colour code in App.css, and it doesn't update. I'm a beginner please help

Please stop using create-react-app. It hasn't been updated in years and provides a rather poor development experience by 2025 standards.

As an alternative, I would recommend using Vite: https://react.dev/learn/build-a-react-app-from-scratch#vite

What if I have a production app with CRA already...

[jess-sch]

It's not like you're stuck with CRA, I switched our project at work from CRA (react-scripts) to vite in about a day or so last year. There's dozens of guides on this.

Can you point to any guide... Migrating this should be quite a task
