--- name: migrate-v8-to-v9 description: Migrate react Table v8 to v9. Audit framework construction, rendering, state, and app hooks, with shared API changes in the core migration skill. metadata: type: lifecycle library: '@tanstack/react-table' library_version: '9.2.6' framework: react requires: - '@tanstack/table-core#migrate-v8-to-v9' sources: - TanStack/table:docs/framework/react/guide/migrating.md - TanStack/table:packages/react-table/src/index.ts - TanStack/table:packages/react-table/src/legacy.ts - TanStack/table:examples/react/basic-use-table --- # React v8-to-v9 migration checklist Before starting, run `intent load @tanstack/table-core#migrate-v8-to-v9`. Audit its entire shared checklist and read the detailed core mappings for APIs present in the application. This checklist adds the React-specific changes. Framework prerequisite: React 18 or newer (`react >=18`). ## Adapter audit - [ ] Replace `useReactTable` with `useTable`; remove any temporary `useLegacyTable` from `@tanstack/react-table/legacy`. - [ ] Keep model inputs stable and use explicit `tableFeatures` plus its row-model slots. Audit every shared change through the core checklist. - [ ] Replace render reads with selected `table.state`, `table.Subscribe`, or `useSelector`. Atom/store snapshots alone do not subscribe React. - [ ] Pair each controlled `state` slice with its updater callback, or supply a stable React Store atom. Remove the global `onStateChange` option. - [ ] Check compiler-memoized children hiding builder-method reads; subscribe inside the child or pass the selected value to it. - [ ] Use `table.FlexRender` or standalone `FlexRender` where appropriate; `flexRender` remains supported. - [ ] Introduce `tableOptions` or `createTableHook` only for repeated conventions; preserve app wrapper and typed-context boundaries. ## Load the affected details When the audit finds old React construction, state, rendering, or app-hook code, read [adapter migration details](references/adapter-migration.md) before editing it. For a replacement render scaffold, read [getting started](../getting-started/SKILL.md). For controlled or stale state after migration, read [table state](../table-state/SKILL.md). Shared pinning, sizing, sorting, selection, prototype-method, type, and registry changes stay in the core migration references. Renaming `useReactTable` alone does not complete the migration. ## Verify the migration - [ ] Type-check against the installed v9 adapter and exercise every enabled client/manual feature flow. - [ ] Verify external state writes, reactive data replacement, and the framework rendering paths changed above. - [ ] Complete the core checklist, including layout and selection behavior when those features are used. - [ ] Replace temporary `stockFeatures` when the target is explicit feature tree-shaking and remove `useLegacyTable`. ## API discovery Inspect `node_modules/@tanstack/react-table/dist/index.d.ts` and the exported adapter declarations. Use `node_modules/@tanstack/table-core/dist/index.d.ts` for shared APIs.
