Client-Side Data Fetching
Client-side fetching is appropriate when data depends heavily on browser interaction, frequent polling, real-time updates, or client-controlled parameters.
Libraries such as SWR or TanStack Query can provide caching, deduplication, retries, refetching, and mutation management.
The correct question is not 'Should I use a data-fetching library?' but 'Where does this data belong and who owns its freshness?'
Key Takeaways
- Use client fetching when browser-driven updates are important.
- Server fetching is usually preferable for initial page content.
- Choose a client data library based on actual state and synchronization requirements.
