With Tanstack Query

This skill builds on @tanstack/table-core#client-vs-server, getting-started, and table-state. Query fetches already processed rows; Table's manual flags only declare that boundary.

Setup

import { keepPreviousData, useQuery } from '@tanstack/preact-query'
import { useCreateAtom, useSelector } from '@tanstack/preact-store'
import {
  rowPaginationFeature,
  tableFeatures,
  useTable,
} from '@tanstack/preact-table'

const features = tableFeatures({ rowPaginationFeature })
const emptyRows: Array<{ id: string }> = []
const paginationAtom = useCreateAtom({ pageIndex: 0, pageSize: 20 })
const pagination = useSelector(paginationAtom, (value) => value)
const result = useQuery({
  queryKey: ['people', pagination],
  queryFn: () => fetchPeople(pagination),
  placeholderData: keepPreviousData,
})
const table = useTable({
  features,
  columns,
  data: result.data?.rows ?? emptyRows,
  rowCount: result.data?.rowCount,
  atoms: { pagination: paginationAtom },
  manualPagination: true,
})

Core Patterns

Key requests by every server-owned slice

useQuery({
  queryKey: ['people', pagination, sorting],
  queryFn: () => fetchPeople({ pagination, sorting }),
})

Pass cached rows directly

useTable({ features, columns, data: result.data?.rows ?? emptyRows })

Common Mistakes

HIGH Importing React Query APIs

Wrong:

import { useQuery } from '@tanstack/react-query'

Correct:

import { useQuery } from '@tanstack/preact-query'

Use native Preact Query and Store integrations throughout the composition.

HIGH Reusing one cache key

Wrong:

useQuery({ queryKey: ['people'], queryFn: () => fetchPeople(pagination) })

Correct:

useQuery({
  queryKey: ['people', pagination],
  queryFn: () => fetchPeople(pagination),
})

Each processed server result needs a key that includes its request state.

HIGH Expecting manual flags to fetch

Wrong:

useTable({ features, columns, data, manualPagination: true })

Correct:

useTable({
  features,
  columns,
  data: result.data?.rows ?? emptyRows,
  rowCount: result.data?.rowCount,
  manualPagination: true,
})

Manual pagination bypasses local processing; it neither calls the backend nor invents totals.

API Discovery

Inspect installed node_modules/@tanstack/preact-table/dist/index.d.ts and the relevant core feature source; inspect @tanstack/preact-query source for exact query APIs.
