React-Query v1.0: Unlocking New Possibilities
Get Ready for a Revolution
The highly anticipated react-query v1.0 has finally arrived, bringing with it a plethora of exciting changes and enhancements. In this article, we’ll dive into the most significant updates, including query keys and functions, the useQuery Hook, queryCache, and the brand-new react-query-devtools.
Query Keys and Functions: Unleashing New Power
The latest version of react-query introduces more serializable members in the array constructor, allowing for more detailed and insightful queries. Additionally, query functions now accept all query key items, enabling them to act on specific queries where they’re called from. This breaking change requires an update to the old method of writing query functions.
useQuery Hook: Streamlined and Efficient
The paginated optional argument has been removed, making way for two new Hooks: usePaginatedQuery and useInfiniteQuery. The useQuery Hook still operates as usual, but with new options and methods, such as isFetchingMore, canFetchMore, and fetchMore.
queryCache: The Heart of React-Query
The queryCache instance is responsible for managing all state activities, caching, lifecycle, and magic of every query. It boasts several methods, including prefetchQuery, getQueryData, setQueryData, refetchQueries, removeQueries, getQuery, isFetching, subscribe, and clear. These methods provide unparalleled control and flexibility when working with queries.
react-query-devtools: Unparalleled Insights
The new react-query-devtools enable you to monitor query operations, view retrieved data, remove queries from cache, and refetch queries. With four indicators of query state (Fresh, Fetching, Stale, and Inactive), you’ll have complete visibility into your application’s query landscape.
What’s Next?
The updates to react-query are nothing short of remarkable. With the addition of devtools, building and debugging apps has never been easier. Stay tuned for more exciting updates and tutorials, and don’t forget to check out the code snippets used in this article. Happy building!
