반응 쿼리 키트

If ur project that uses react-query and only focus on frontend. I would prefer u to use react-query-kit to make ur experience with react-query more simply and type-safe.

이점

일관성을 고려하지 않고 queryKey를 관리합니다

.

react-query-kit으로 생성된 u를 통해 사용자 정의 후크를 더 안전한 유형으로 만듭니다

설치

이 모듈은 npm과 번들로 제공되는 node을 통해 배포되며
프로젝트dependencies 중 하나로 설치해야 합니다.

npm install --save react-query-kit @tanstack/react-query

createQuery

용법

import { QueryClient, dehydrate } from '@tanstack/react-query'
import { createQuery } from 'react-query-kit'

type Response = { title: string; content: string }
type Variables = { id: number }

const usePost = createQuery<Response, Variables, Error>({
  primaryKey: '/posts',
  queryFn: ({ queryKey: [primaryKey, variables] }) => {
    // primaryKey equals to '/posts'
    return fetch(`${primaryKey}/${variables.id}`).then(res => res.json())
  },
})


const variables = { id: 1 }

// example
export default function Page() {
  // queryKey equals to `['/posts', { id: 1 }]`
  const { data } = usePost({ variables, suspense: true })

  return (
    <div>
      <div>{data?.title}</div>
      <div>{data?.content}</div>
    </div>
  )
}

// nextjs example
export async function getStaticProps() {
  const queryClient = new QueryClient()

  await queryClient.prefetchQuery(usePost.getKey(variables), usePost.queryFn)

  return {
    props: {
      dehydratedState: dehydrate(queryClient),
    },
  }
}

// usage outside of react component
const data = await queryClient.fetchQuery(
  usePost.getKey(variables),
  usePost.queryFn
)

// useQueries example
const queries = useQueries({
  queries: [
    { queryKey: usePost.getKey(variables), queryFn: usePost.queryFn },
    { queryKey: useProjects.getKey(), queryFn: useProjects.queryFn },
  ],
})

// setQueryData
queryClient.setQueryData(usePost.getKey(variables), {...})

// set data to all queries of `post`
queryClient.setQueriesData([usePost.getKey()], {...})
// or set data to some speicial queries of `post`
queryClient.setQueriesData(usePost.getKey(variables), {...})

// invalidate all queries of `post`
queryClient.invalidateQueries(usePost.getKey())
// or invalidate some speicial queries of `post`
queryClient.invalidateQueries(usePost.getKey(variables))

primaryKey는 queryKey 배열의 첫 번째 요소가 됩니다.

createInfiniteQuery

용법

import { QueryClient, dehydrate } from '@tanstack/react-query'

type Data = { projects: { id: string; name: string }[]; nextCursor: number }
type Variables = { active: boolean }

  queryFn: ({ queryKey: [_primaryKey, variables], pageParam = 1 }) => {
    return fetch(`/projects?cursor=${pageParam}?active=${variables.active}`).then(res => res.json())
  },
  getNextPageParam: (lastPage, pages) => lastPage.nextCursor,
})

const variables = { active: true }

// example
export default function Page() {
  // queryKey equals to `['projects', { active: true }]`
  const { data, fetchNextPage, hasNextPage, isFetching, isFetchingNextPage } =
    useProjects({ suspense: true, variables })

  return (
    <div>
      {data.pages.map((group, i) => (
        <React.Fragment key={i}>
          {group.projects.map(project => (
            <p key={project.id}>{project.name}</p>
          ))}
        </React.Fragment>
      ))}
      <div>
        <button
          onClick={() => fetchNextPage()}
          disabled={!hasNextPage || isFetchingNextPage}
        >
          {isFetchingNextPage
            ? 'Loading more...'
            : hasNextPage

        </button>
