react/migrate-v8-to-v9

What problem does it solve?

This skill removes confusion and breakages when upgrading @tanstack/react-table from v8 to v9 by translating the old API shape, state model, and generics into the new _features/_rowModels architecture.

Core Features & Use Cases

• Two migration paths: direct React v9 migration or a temporary v8 compatibility bridge via useLegacyTable for large codebases that can’t be refactored in one PR.
• Mechanical API rewrites: maps v8 entries like useReactTable, get*RowModel options, sortingFn/sortingFns, and table.getState() reads into the v9 equivalents like useTable, _rowModels factories, sortFn/sortFns, and store/atoms/Subscribe-based access.
• Type-safe guidance: updates ColumnMeta/ColumnDef generics to the v9-required TFeatures-first form and calls out runtime/type failures such as mutating readonly columns/data.

Quick Start

Ask an AI coding agent to migrate your existing @tanstack/react-table v8 table code to the v9 API by applying the direct useTable path first, then adjust state reads to use table.Subscribe or table.atoms instead of table.getState().
