React 18 | Tutorial Suspense | Data Fetching | SWR

Half the code in a typical React component is loading and error boilerplate. React 18's Suspense plus SWR deletes most of it: components suspend while data loads, a fallback shows automatically, and you just render the result. I set it up from scratch in the video, starting with a fresh Vite project and the React 18 upgrade.

This is for React devs who want cleaner components and a real understanding of how Suspense changes data fetching.

What's inside

• Create a React project with Vite and upgrade it to React 18
• Swap ReactDOM.render for the new createRoot API
• Write one fetcher function and reuse it across all SWR hooks
• Enable suspense: true in the SWRConfig provider
• Show fallback UI automatically while data loads
• Strip manual loading and error checks out of your components
