为了创建一个完整的 ReactJS + TypeScript + Vite 示例,其中包括使用 Redux (Thunk) 和 React Query (TanStack) 进行 CRUD 操作,我们将设置一个 Node.js Express 服务器,使用 JSON 文件作为数据来源。这个服务器将提供 API 端点来模拟真实的后端。快速了解一下 TypeScript 的特点 下面,概览: 前端:使用React+V...
想要请求接口: 使用queryClient.invalidateQueries(queryKey),传入需要重新认证的 queryKey,React-Query 会把指定的 query 状态设置成失效,然后重新请求接口拉取数据。 const queryClient = useQueryClient(); // 拿到query客户端 const mutation = useMutation((body) => createTodoApi(body), { onSuccess: (data...
更多使用姿势可以参考文档:https://swr.vercel.app/zh-CN/docs/mutation Typescript 支持 SWR 的 typescipt 支持非常好,毕竟自身就是用 ts 实现的。如果我们想要在使用 hook 时为请求的响应值提供类型,只需要传入一个泛型就OK,如下例: 代码语言:javascript ...
type Query { getMessage(id: ID!): Message } type Mutation { createMessage(input: MessageInput): Message updateMessage(id: ID!, input: MessageInput): Message } GraphQL还是通过Http的GET和POST的方式返回数据,只是GET的长度限制导致可能的查询会出问题。所以一般都可以用POST来获取、修改数据。这就是说...
A good way to debug your function on the React Query devtools is to pass an object as a second argument. Inside this object, you can pass a mutation key, and a few more functions such as onError, onSuccess, onMutate, onSettled and useErrorBoundary. ...

Since I'm working on the PR I would like to know if I need to handle some extra case - right now the fix is that we allow to return anything from mutation exceptundefined.undefinedis allowed in mutations by react-query but it's not valid JSON so it's not like you can get it as...
