migrate-v8-to-v9

name	migrate-v8-to-v9
description	Perform a complete @tanstack/solid-table v8-to-v9 migration: createTable, explicit features and row-model slots, getter-based Solid reactivity, atom state, rendering, composable tables, type helpers, and every shared API rename and semantic change. Use for migration plans, implementation, or audits.

Read @tanstack/table-core#migrate-v8-to-v9, getting-started, and table-state. Use this as the exhaustive Solid migration checklist. Check the installed declarations before emitting APIs for a different v9 version.

Framework prerequisite: Solid 1.3 or newer (solid-js >=1.3).

Target architecture

import {
  createSortedRowModel,
  createTable,
  rowSortingFeature,
  tableFeatures,
} from '@tanstack/solid-table'

const features = tableFeatures({
  rowSortingFeature,
  sortedRowModel: createSortedRowModel(),
})

const table = createTable({
  features,
  columns,
  get data() {
    return data()
  },
})

Keep static features and columns outside reactive component work. Prefer explicit features as the end state; stockFeatures is a kitchen-sink migration shortcut.

Construction and feature registration

v8	v9
createSolidTable(options)	createTable({ ...options, features })
Every feature bundled	Register used *Feature objects with tableFeatures()
getCoreRowModel() option	Remove it; core is automatic
getFilteredRowModel()	filteredRowModel: createFilteredRowModel()
getSortedRowModel()	sortedRowModel: createSortedRowModel()
getPaginationRowModel()	paginatedRowModel: createPaginatedRowModel()
getExpandedRowModel()	expandedRowModel: createExpandedRowModel()
getGroupedRowModel()	groupedRowModel: createGroupedRowModel()
getFacetedRowModel()	facetedRowModel: createFacetedRowModel()
getFacetedMinMaxValues()	facetedMinMaxValues: createFacetedMinMaxValues()
getFacetedUniqueValues()	facetedUniqueValues: createFacetedUniqueValues()
Table/factory sortingFns, filterFns, aggregationFns	sortFns, filterFns, aggregationFns feature slots
Removed rowModels: { ... }	Direct named slots in tableFeatures()

In the registry slots, register individually imported built-ins (filterFn_includesString, sortFn_alphanumeric, aggregationFn_sum, and so on) under their conventional keys alongside custom functions; the full filterFns/sortFns/aggregationFns registry objects still work but bundle every built-in.

Place each prerequisite feature before its row-model slot. Stock features are cellSelectionFeature, columnFilteringFeature, globalFilteringFeature, rowSortingFeature, rowPaginationFeature, rowSelectionFeature, rowExpandingFeature, rowPinningFeature, columnPinningFeature, columnVisibilityFeature, columnOrderingFeature, columnSizingFeature, columnResizingFeature, rowAggregationFeature, columnGroupingFeature, and columnFacetingFeature. Aggregation is independent from grouping: register rowAggregationFeature for aggregation APIs and add columnGroupingFeature only for grouped rows.

Solid state and reactivity

v8	v9
table.getState()	table.atoms.<slice>.get() in tracked scopes, or broad table.store.get()
Top-level onStateChange	Per-slice callbacks or table.store.subscribe()
Eager signal values in options	Getters for reactive data and controlled state slices
Whole-state rendering	Narrow atom reads, createMemo, or table.Subscribe

const [sorting, setSorting] = createSignal<SortingState>([])
const table = createTable({
  features,
  columns,
  get data() {
    return data()
  },
  state: {
    get sorting() {
      return sorting()
    },
  },
  onSortingChange: setSorting,
})

table.Subscribe passes atoms to its child. A Solid component child body is untracked, so read atoms inside JSX expressions or a thunk invoked by JSX:

<table.Subscribe>
  {(atoms) => <span>Page {atoms.pagination.get().pageIndex + 1}</span>}
</table.Subscribe>

Use createAtom/useSelector from @tanstack/solid-store for externally owned slices. An external atom wins over state for the same slice; do not combine ownership models accidentally.

Rendering and composition

• Replace flexRender(def, context) with <FlexRender header={header} /> or <table.FlexRender cell={cell} />.
• Use tableOptions() for typed reusable option fragments.
• Use createTableHook({ features, ...defaults }) for repeated conventions; it returns helpers such as createAppTable and createAppColumnHelper.
• Invoke row/cell/column/header methods through their instance. Prototype methods lose this when extracted and are absent from object spread, Object.keys, and JSON. Table-instance methods are not affected.

TypeScript and helper changes

v8	v9
createColumnHelper<Person>()	createColumnHelper<typeof features, Person>()
Plain nested column arrays	columnHelper.columns([...]) for TValue inference
ColumnDef<TData>	ColumnDef<TFeatures, TData, TValue>
Column<TData>, Row<TData>, Table<TData>	Add TFeatures first
Cell<TData, TValue>	Cell<TFeatures, TData, TValue>
TableMeta<TData> / ColumnMeta<TData, TValue>	Add TFeatures, or use per-table tableMeta / columnMeta with metaHelper()
Global FilterFns, SortFns, AggregationFns, and FilterMeta augmentation	filterFns, sortFns, aggregationFns, and filterMeta slots
RowData = unknown	Record or array row data

Infer with typeof features; use StockFeatures only when deliberately typing stockFeatures.

Shared API and semantic changes

v8 pinning	v9
columnPinning.left / .right	.start / .end
column.pin('left' | 'right')	column.pin('start' | 'end')
getIsPinned() === 'left' | 'right'	'start' | 'end'
row.getLeftVisibleCells() / getRightVisibleCells()	getStartVisibleCells() / getEndVisibleCells()
getLeftHeaderGroups() / getRightHeaderGroups()	getStartHeaderGroups() / getEndHeaderGroups()
getLeftFooterGroups() / getRightFooterGroups()	getStartFooterGroups() / getEndFooterGroups()
getLeftFlatHeaders() / getRightFlatHeaders()	getStartFlatHeaders() / getEndFlatHeaders()
getLeftLeafHeaders() / getRightLeafHeaders()	getStartLeafHeaders() / getEndLeafHeaders()
getLeftLeafColumns() / getRightLeafColumns()	getStartLeafColumns() / getEndLeafColumns()
getLeftVisibleLeafColumns() / getRightVisibleLeafColumns()	getStartVisibleLeafColumns() / getEndVisibleLeafColumns()
getLeftTotalSize() / getRightTotalSize()	getStartTotalSize() / getEndTotalSize()
column.getStart('left')	column.getStart('start')
column.getAfter('right')

Logical pinning does not implement DOM direction styling; use logical CSS insets. columnResizeDirection is unchanged.

v8	v9
Table enablePinning	enableColumnPinning plus enableRowPinning; column-level option remains
Combined sizing/resizing	columnSizingFeature; add columnResizingFeature for interaction
columnSizingInfo / onColumnSizingInfoChange	columnResizing / onColumnResizingChange
setColumnSizingInfo()	setColumnResizing()
sortingFn / sortingFns	sortFn / sortFns
getSortingFn() / getAutoSortingFn()	getSortFn() / getAutoSortFn()
SortingFn / SortingFns	SortFn / SortFns
row._getAllCellsByColumnId()	row.getAllCellsByColumnId()
table._getPinnedRows()	getTopRows(), getCenterRows(), or getBottomRows()
table._getFacetedRowModel()	Public faceting APIs on the relevant column/table
table._getFacetedMinMaxValues()	getFacetedMinMaxValues()
table._getFacetedUniqueValues()	getFacetedUniqueValues()

All other underscore-prefixed internals are removed. getIsSomeRowsSelected() and getIsSomePageRowsSelected() now mean at least one even when all are selected. Use getIsSomeRowsSelected() && !getIsAllRowsSelected() or getIsSomePageRowsSelected() && !getIsAllPageRowsSelected() for checkbox indeterminate state.

Migration procedure

1. Replace createSolidTable with createTable and inventory used features, processing, state, and APIs.
2. Build tableFeatures() in prerequisite order; remove getCoreRowModel and old row-model placement.
3. Apply all pinning, sizing, sorting, row, and selection mappings above.
4. Update helpers/types with typeof features; migrate meta and function augmentation to per-feature slots where appropriate.
5. Preserve Solid tracking with getters for data and controlled state; replace getState() and onStateChange.
6. Choose internal, controlled-signal, or external-atom ownership per slice.
7. Replace unbound row/cell/column/header methods and migrate rendering.
8. Add tableOptions, table.Subscribe, or createTableHook only where composition or fine-grained rendering calls for them.
9. Type-check and exercise every enabled client- and server-side flow.
10. Audit away stockFeatures when production tree-shaking matters.

Final migration checklist

• Replace createSolidTable with createTable and preserve reactive inputs through getters.
• Register every used stock feature explicitly and order prerequisites before slots.
• Remove getCoreRowModel; move all eight optional row models into tableFeatures.
• Move filterFns, sortFns, aggregationFns, and filterMeta into feature slots.
• Replace table.getState() and onStateChange with tracked atom/store reads, per-slice callbacks, subscriptions, or external atoms.
• Audit Solid tracking scopes, controlled getters, atom precedence, and reset ownership.
• Replace unbound/copied row, cell, column, and header methods.
• Apply the complete logical pinning map and CSS changes.
• Split pinning options and sizing/resizing; rename the resizing state, setter, and callback.
• Apply every sorting rename and remove each listed internal API.
• Pair some-selected with the matching all-selected predicate.
• Update TFeatures helpers/types, columns(), StockFeatures, meta/registry slots, and RowData.
• Migrate Solid FlexRender and use tableOptions/createTableHook only for repeated conventions.
• Type-check and exercise every enabled client/manual feature and LTR/RTL layout flow.
• Audit away temporary stockFeatures usage when explicit tree-shaking is intended.

Common migration failures

• Calling createTable({ data: data() }) and freezing the initial array instead of providing a getter.
• Leaving row models in table options or omitting their prerequisite feature.
• Reading atoms in an untracked component child body and expecting Solid updates.
• Supplying controlled state without getter properties or per-slice callbacks.
• Destructuring prototype-backed object methods.
• Updating pinning state names but not CSS and region APIs.
• Treating changed “some selected” semantics as checkbox indeterminate state.

API discovery

Inspect node_modules/@tanstack/solid-table/dist/index.d.ts and node_modules/@tanstack/table-core/dist/index.d.ts. Compare v8 names only against the migration guide, not current main-branch assumptions.
