Waiting for queries to become stale before they are fetched again doesn't always work, especially when you know for a fact that a query's data is out of date because of something the user has done. Fo...
queryClient.invalidateQueries({ queryKey: mutation.options.mutationKey, }) }, }), }) 这样一来就可以通过定义时的mutationKey去让对应queryKey的数据失效,触发重新执行对应的queryFn请求数据,如果你没有提供mutationKey,它仍然会让所有匹配的活跃查询失效。 根据staleTime 排除 Queries 我经常通过给查询设置staleT...
需要在根组件中引入QueryClient,QueryClientProvider,用QueryClientProvider对根组件进行包裹,再用 QueryClient new一个实例,将实例使用Context的方式提供给整个App import {QueryClient,QueryClientProvider} from "@tanstack/react-query"; // 创建一个 client const queryClient = new QueryClient(); function App()...
QueryClient The QueryClient can be used to interact with a cache: tsx import { QueryClient } from '@tanstack/react-query' const queryClient = new QueryClient({ defaultOptions: { queries: { staleTime:...
在tanStack Query(以前称为 React Query)中,isPending 和 isFetching 都是用来描述查询状态的布尔值属性,但它们表示的是不同阶段和情况下的加载状态。理解两者的区别有助于更好地管理应用中的加载指示器和用户界面反馈。 isFetching 定义:isFetc

React Query provides two ways to optimistically update your UI before a mutation has completed. You can either use the onMutate option to update your cache directly, or leverage the returned variables...

TanStack/query 的源码地址:github.com/TanStack/que 二者的目标是相同的,即减少网络请求和优化性能,但它们的实现方式和一些功能存在一些不同之处。我们先做一个关于SWR和TanStack Query的一些整体功能对比: 一、实现方式 SWR是一个轻量级的React Hook库,它提供了一个名为useSWR的Hook,通过它可以方便地使用缓存...
