migrate-v8-to-v9

Use this as the complete breaking-change checklist. V9 is the current API; do not stop after renaming the Vue composable.

Framework prerequisite: Vue 3.2 or newer (vue >=3.2).

Recommended Migration Order

1. Replace useVueTable with useTable while preserving reactive inputs.
2. Define explicit features, then move row models and registries into tableFeatures.
3. Update state reads, controlled ownership, and rendering.
4. Apply every shared API and type rename below.
5. Use stockFeatures only as a temporary audit bridge; explicit features are the production target.

const features = tableFeatures({
  rowSortingFeature,
  sortedRowModel: createSortedRowModel(),
  sortFns: { alphanumeric: sortFn_alphanumeric },
})
const data = ref(makeData())
const table = useTable({ features, columns, data })

Construction and Feature Registration

Available feature imports are columnFilteringFeature, globalFilteringFeature, rowSortingFeature, rowPaginationFeature, rowSelectionFeature, rowExpandingFeature, rowPinningFeature, columnPinningFeature, columnVisibilityFeature, columnOrderingFeature, columnSizingFeature, columnResizingFeature, rowAggregationFeature, columnGroupingFeature, and columnFacetingFeature. APIs are feature-gated. Put every feature before its dependent slot in the same tableFeatures call. Aggregation is independent from grouping: register rowAggregationFeature for aggregation APIs and add columnGroupingFeature only for grouped rows.

Row-model mapping

Factories take no arguments. Register filterFns, sortFns, and aggregationFns as sibling feature slots holding individually imported built-ins (filterFn_includesString, sortFn_alphanumeric, aggregationFn_sum) under their conventional keys. The full registry objects still work but bundle every built-in.

Vue State Migration

• Pass a ref or computed as data; the adapter unwraps and syncs it. Do not pass data.value, which is only a snapshot. A getter returning data.value is also supported.
• table.getState().sorting becomes the narrow table.atoms.sorting.get(). Use table.store.get() only for a full snapshot/debug output.
• Wrap atom reads in Vue computed when deriving template values.
• In JSX/render functions, table.Subscribe provides a fine-grained boundary. Pass the callback as the explicit children prop because Vue JSX element children become slots.
• Controlled refs need getter-backed state slices plus per-slice callbacks that resolve value-or-function Updaters.
• The top-level onStateChange is removed. Use per-slice callbacks, external atoms, or table.store.subscribe to observe everything.
• External atoms come from @tanstack/vue-store and are supplied through atoms. Never provide both atoms.pagination and state.pagination.
• table.baseAtoms is internal writable state; prefer feature APIs or external atoms.

Rendering and Composition

The old render/props FlexRender shape still compiles, but shorthand is the migration target. createTableHook is optional and intended for application-wide conventions.

Complete Shared Breaking-Change Map

Instance methods

Row, cell, column, header, and related methods now live on shared prototypes and use this. Call them on their instances. Do not destructure them, pass them bare, or expect them in object spread, Object.keys, or JSON. Table methods are not affected.

Logical column pinning

There are no left/right aliases in beta.38.

Use CSS inset-inline-start/inset-inline-end; logical names do not automatically set DOM direction. columnResizeDirection is unchanged.

Pinning, sizing, and resizing

• enablePinning splits into enableColumnPinning and enableRowPinning.
• Interactive resizing requires columnSizingFeature plus columnResizingFeature; fixed sizing needs only the former.
• columnSizingInfo becomes columnResizing.
• setColumnSizingInfo() becomes setColumnResizing().
• onColumnSizingInfoChange becomes onColumnResizingChange.

Sorting, rows, and selection

Other _-prefixed internals are removed, including _getPinnedRows, _getFacetedRowModel, _getFacetedMinMaxValues, and _getFacetedUniqueValues.

getIsSomeRowsSelected() and getIsSomePageRowsSelected() now mean at least one, including all. Indeterminate UI must also check !getIsAllRowsSelected() or !getIsAllPageRowsSelected().

TypeScript Migration

• Add TFeatures first: ColumnDef<typeof features, Person>, Column<typeof features, Person>, Row<typeof features, Person>, Table<typeof features, Person>.
• Replace createColumnHelper<Person>() with createColumnHelper<typeof features, Person>(); use columnHelper.columns([...]) for nested-array inference.
• Use StockFeatures when stockFeatures is the configuration.
• Existing TableMeta/ColumnMeta declaration merging must add TFeatures first. Prefer per-table tableMeta/columnMeta: metaHelper<...>() slots.
• Replace global FilterFns, SortFns, AggregationFns, and FilterMeta augmentation with registry slots and filterMeta: metaHelper<...>(); registered keys become valid strings in column defs.
• RowData is restricted to records or arrays; prefer explicit object row types.

Common Migration Failures

HIGH: Renaming only the composable

useTable({ getSortedRowModel: ... }) is still a v8 configuration. Move the row model and its prerequisite feature into tableFeatures.

HIGH: Unwrapping refs before useTable

Pass data, not data.value, or use a getter. Preserve the reactive source.

HIGH: Passing prototype methods bare

Use row.getValue('name'), not const read = row.getValue; shallow copies also lose methods.

MEDIUM: JSX children as slots

For table.Subscribe, use children={(atoms) => ...} explicitly.

Final Checklist

• useVueTable is replaced with useTable; refs/computed inputs remain reactive.
• Features, row models, and registries are in tableFeatures; core row model is removed.
• State reads use atoms/computed or the store intentionally; onStateChange is removed.
• External atom and controlled state ownership do not overlap.
• FlexRender shorthand is adopted where applicable.
• Prototype methods, pinning, sizing/resizing, sorting, row, and selection changes are audited.
• Helpers, types, meta, registries, and RowData use v9 shapes.
• Temporary stockFeatures usage has an explicit removal plan.

API Discovery

Inspect node_modules/@tanstack/vue-table/dist/index.d.ts and useTable.d.ts; verify feature slots and exact beta APIs in node_modules/@tanstack/table-core/dist/. Do not reconstruct v9 from v8 memory.
