With Tanstack Query

This skill builds on @tanstack/table-core#client-vs-server, getting-started, and table-state. Decide the server-owned stages and dataset before wiring Query.

Setup

import {
  injectQuery,
  keepPreviousData,
} from '@tanstack/angular-query-experimental'
import { signal } from '@angular/core'
import {
  injectTable,
  rowPaginationFeature,
  tableFeatures,
} from '@tanstack/angular-table'

const features = tableFeatures({ rowPaginationFeature })
const EMPTY_ROWS: never[] = []

export class PeopleTable {
  readonly pagination = signal({ pageIndex: 0, pageSize: 20 })
  readonly query = injectQuery(() => ({
    queryKey: [
      'people',
      this.pagination().pageIndex,
      this.pagination().pageSize,
    ],
    queryFn: () =>
      fetch(
        `/api/people?page=${this.pagination().pageIndex}&size=${this.pagination().pageSize}`,
      ).then((r) => r.json()),
    placeholderData: keepPreviousData,
  }))
  readonly table = injectTable(() => ({
    features,
    columns,
    data: this.query.data()?.rows ?? EMPTY_ROWS,
    rowCount: this.query.data()?.rowCount ?? 0,
    manualPagination: true,
    state: { pagination: this.pagination() },
    onPaginationChange: (next) =>
      typeof next === 'function'
        ? this.pagination.update(next)
        : this.pagination.set(next),
  }))
}

Core Patterns

Track every server-owned input

Read pagination, sorting, and filtering signals inside injectQuery(() => ...) and include them in the query key. Return data already processed for each manual stage.

Keep Query data authoritative

Read the Query signal directly in injectTable. Create another signal only for a deliberate editable draft with an explicit cache synchronization policy.

Common Mistakes

HIGH Capturing query inputs outside tracking

Wrong:

const page = this.pagination().pageIndex
readonly query = injectQuery(() => ({ queryKey: ['people', page], queryFn }))

Correct:

readonly query = injectQuery(() => ({ queryKey: ['people', this.pagination().pageIndex], queryFn }))

Signal reads inside the options function establish refetch dependencies.

HIGH Expecting manual mode to request

Wrong:

injectTable(() => ({ features, columns, data, manualPagination: true }))

Correct:

injectTable(() => ({
  features,
  columns,
  data: this.query.data()?.rows ?? EMPTY_ROWS,
  manualPagination: true,
}))

Manual flags only bypass client row processing; Query performs network work.

HIGH Omitting total counts

Wrong:

{ data: this.query.data()?.rows ?? EMPTY_ROWS, manualPagination: true }

Correct:

{ data: this.query.data()?.rows ?? EMPTY_ROWS, rowCount: this.query.data()?.rowCount ?? 0, manualPagination: true }

Table needs rowCount or pageCount to constrain navigation across server pages.

API Discovery

Inspect installed @tanstack/angular-table/dist/types/, the relevant core feature source, and installed Angular Query source for the exact injectQuery package/version contract.
