In the examples below I keep a ref for the params, if they are changed I can trigger the query to reset via useLayoutEffect hook. This part works as expectedinvalidateQueries attemptqueryClient.invalidateQueries( [queryKey, JSON.stringify(paramsRef.current)], { exact: true, refetchActive: ...
useEffect(() => { // Trigger rerendering whenever query state changes return observerRef.current.subscribe(rerender); }, []); return observerRef.current.getResult(); } 结语 针对服务端数据交互这一场景应运而生的 React Query 为轻交互、重数据的业务场景提供了极大的开发上的便利。很多应用甚至...
The problem I am facing is that in this current state when the handleRefetchUsers() function triggers it works as expected. However, if I am to uncomment all the asynchronous code which I need to run on every click to document the event, once the handleRefetchUsers() trigger I notice ...
我们为了保留queryStringObject的标识使用了useMemo()进行包裹,但最终依然会产生不必要的fetchUsers的调用。 当用户更新 displayMode 时(这种模式只进行 re-rendering,而并非触发 re-fetch),querystring将会变化,从而导致querystring会被再次解析,而解析又会导致新的 filter 属性的对象生成,最终导致不必要的useEffect被执行。
onSuccess(_data, query) { if (listOfQueryKeysToTriggerAnotherFetch.indexOf(query.queryKey[0]) !== -1) { queryClient.cancelQueries({ queryKey: [queryKeys.YOUR_KEY_YOU_WANT_TO_REFETCH], }); queryClient.invalidateQueries({ queryKey: [queryKeys.YOUR_KEY_YOU_WANT_TO_REFETCH], ...
fetchEpoch(), { retryDelay: 5 * 1000, initialData: null, } ) useInterval(() => { if (!epochData || !timing) return if (shouldRefetchEpoch(epochData, timing)) { const currentTime = new Date().getTime() if (Math.abs(currentTime - lastModifiedEpochTime > 15 * 1000)) { query...
In react-query, the cache is not re-fetched when it is converted from fresh(最新) to stale(老旧) state. Instead, it relies on the following five trigger conditions to re-fetch data data: ①When the component is mounted When the component is first loaded, it will trigger the data fetchi...
you can just trigger a refetch for your optimistic queries to revert them to their true server state. In some circumstances though, refetching may not work correctly and the mutation error could represent some type of server issue that won't make it possible to refetch. In this event, you...
Query Key: This has to be a unique key for a response of an API. React-query uses this to serialize and cache the response data by an API endpoint. This cache is accessible globally in the app. If we request again using the same query, it won’t trigger a re-fetch and bring the...
