Fetching data in React often means using stale state and complex caching logic.
React Query simplifies data fetching with powerful features like automatic caching, deduplication, and background updates.
Let’s explore some key features of React Query:
Declarative Data Fetching
Fetch data with the
useQuery handles declaring cache keys, performing fetches, and more.
React Query automatically refetches “inactive” queries in the background:
Stale data is updated without blocking the UI.
Duplicate requests are deduped to prevent wasteful refetches:
React Query shares cache results across components.
Mutations can update the cache optimistically before fetching:
This makes the UI feel fast and responsive.
- Simplifies data fetching with useQuery
- Refetches stale data in background
- Deduplicates requests automatically
- Optimistic updates make UI feel snappy
React Query takes the pain out of async data management!
