Preact 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 Preact-specific changes.

Framework prerequisite: Preact 10 or newer (preact >=10).

Adapter audit

  • Replace React-adapter imports and useReactTable with native @tanstack/preact-table and useTable.
  • Remove compat aliases that existed only for Table. Preserve aliases still required by other libraries, including a React Virtual integration.
  • Keep model inputs stable and configure explicit features/row-model slots; complete the shared core checklist.
  • Use selected table.state, table.Subscribe, or Preact Store subscriptions; snapshots alone do not rerender consumers.
  • Pair controlled slices with callbacks, or supply stable atoms from @tanstack/preact-store; remove global onStateChange.
  • Use native Preact FlexRender components. Adopt tableOptions or createTableHook only for repeated app conventions.

Load the affected details

When the audit finds old Preact construction, state, rendering, or app-hook code, read adapter migration details before editing it. For a replacement render scaffold, read getting started. For controlled or stale state after migration, read table state.

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.

API discovery

Inspect node_modules/@tanstack/preact-table/dist/index.d.ts and the exported adapter declarations. Use node_modules/@tanstack/table-core/dist/index.d.ts for shared APIs.
