Episode notes
Spinner Hell
- Dev Agrawal reflects on past projects where multiple loading states created a confusing user experience.
- He cites Twitter and Notion as examples of websites with this spinner hell issue.
Prioritize Important Content
- Waiting for the slowest data to load before rendering isn't always ideal.
- Prioritize displaying important content first, using asynchronous UI patterns like try-catch to manage separate data sources efficiently.
Suspense Boundaries
- React's Suspense boundaries offer a solution to asynchronous UI challenges by wrapping UI components and declaring asynchronous data sources.
- This lets components suspend rendering until data is fetched, showing a fallback UI and preventing intermediate loading states.
