useMutation 虽然名为 “修改”,但是真正清除缓存是需要依靠 queryClient 的。 import { useMutation, useQueryClient } from "@tanstack/react-query"; const queryClient = useQueryClient(); // mutation 后会重新请求 useQuery({ queryKey: ['todos', { type: 'calendar'}], }) // mutation 后不会...
isLoading,error}=useQuery("getStar",()=>axios.get("https://api.github.com/repos/tannerlinsley/react-query"));if(isLoading)return"数据获取中...";if(error)return"发生错误: "+error.message;return(react-query获得了{data.stargazers_count}颗星);}复制代码 在这里使用use...

For that, React Query has mutations. Unlike queries, mutations accept callbacks that will be executed onSuccess, onError, and onMutate (when the mutation is started). And return a mutate function to perform the function you passed to mutationFn. Let's look at an example: export const useCr...

现在客户端连接到服务器,我们可以开始真正的任务 - 编写一个mutation,将channel添加到我们的channel列表中。 首先,我们将通过将其添加到server / src / schema.js中来定义模式中的mutation: const typeDefs = type Channel { id: ID! # "!" denotes a required field name: String}type Query { channels: [...
queryClient?: QueryClient, Use this to use a custom QueryClient. Otherwise, the one from the nearest context will be used. Returns mutate: (variables: TVariables, { onSuccess, onSettled, onError }) => void The mutation function you can call with variables to trigger the mutation and opti...
QueryClient에서 모든 query 또는 mutation에 기본 옵션을 추가할 수 있으며, 종류가 상당하므로 공식 문서를 참고해 보자.import { QueryClient, QueryClientProvider } from "@tanstack/react-query"; const queryClient = new QueryClient...
可以在一次http请求中,实现数据的mutation和query,更加高效 // page.tsx import { createUser, fetchUsers, User } from "../actions/users"; const UserList = async () => { const userList = await fetchUsers(); // 直接调用服务端函数
