queryKey: unknown[] Required The query key to use for this query. The query key will be hashed into a stable hash. SeeQuery Keysfor more information. The query will automatically update when this key changes (as long asenabledis not set tofalse). ...
react-query 首先通过检查查询缓存[2]来确定数据是否已经被获取。如果数据不在缓存中,或者缓存的数据已经过期,react-query将发送一个 HTTP 请求到 API Server[3]来检索数据,然后将数据存储在缓存中[4]。最后,react-query 从缓存中[5]拿到数据,将数据返回给用户 。 React-query 中的缓存是一个轻量级的,基于内存...
import { useQuery } from '@tanstack/react-query' const dataSourceQuery = useQuery(['dataSourceQuery'], () => api.getUseList()) svelte中使用 和react中一样先对根组件进行包裹,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 '@tan...
3. queryClient.getQueryData与useQuery获取共享数据的区别 比如页面加载的时候使用useQuery请求到了数据,被@tanstack/react-query缓存了起来,在其他组件里想拿到该数据,通常会直接调用useQuery获取数据,但是在项目里出了问题,如下图,我在两个节点拖拽无法建立连线,因为线跟后端返回的数据是管理的,边节点里面调用了use...
A query function can be literally any function that returns a promise. The promise that is returned should either resolve the data or throw an error. All of the following are valid query function conf...

TanStack Query是一个基于React Hooks的轻量级查询库,它提供了简单易用的API来处理数据查询和数据变更的逻辑。它的核心是QueryClient,它是一个全局状态管理器,可以帮助我们从多个组件中访问和共享数据查询结果。 使用TanStack Query,我们可以通过编写自定义的查询函数来发送请求,并使用useQuery钩子来获取查询结果。此外,...
