Run 6: Item-grid Integration — Implementation Summary

Date: 2026-03-19 Branch: jmpicnic/component-consolidation Status: Complete — all exit criteria pass

Task Completion

Task	Status	Notes
6.1 Evaluate factory config vs wrapper	Done	Thin wrapper required (see decision below)
6.2 Create item-grid implementation	Done	Thin wrapper over createEntityDataGrid
6.3 Replace useItemGridEditing	Done	Deleted; entity-data-grid useRowAutoPublish used
6.4 Replace inline search, drag-to-scroll, toolbar, actions	Done	All delegated to entity-data-grid factory config
6.5 Preserve domain-specific code	Done	Curated columns, typeahead lookups, renderers all preserved
6.6 Update item-grid stories	Done	Stories updated; gridRef changed to ItemGridHandle
6.7 Update item-grid unit tests	Done	3 count-label assertions updated for new format

Decision: Thin Wrapper with Design-Time Factory Config

Assessment: item-grid uses createEntityDataGrid as its base via a thin forwardRef wrapper that calls the factory inside useMemo. All item-domain configuration is design-time:

1. onNotesClick callback — passed to createItemGridColumnDefs(lookups, { onNotesClick }) at factory creation time. NotesCellRenderer reads it from cellRendererParams (not AG Grid context). No gridContext needed.

2. getGridApi() (raw AG Grid API access) — added to EntityDataGridRef for imperative operations (column visibility, deselectAll).

Post-implementation cleanup: An initial approach added gridContext/gridContextOverride to entity-data-grid and DataGrid molecule. This was reverted per the project owner’s design correction — onNotesClick and lookups are stable design-time values, not runtime props. The cellRendererParams approach is the AG Grid-idiomatic solution.

Modified files

src/components/canary/organisms/shared/entity-data-grid/create-entity-data-grid.tsx

• Added getGridApi(): GridApi | null to EntityDataGridRef
• Wired getGridApi() in useImperativeHandle via gridRef.current?.getGridApi()
• Removed gridContext (factory config) and gridContextOverride (view prop) — not needed after cleanup

src/components/canary/organisms/shared/entity-data-grid-shim/create-entity-data-grid-shim.tsx

• Added getGridApi: () => baseRef.current?.getGridApi() ?? null to useImperativeHandle to satisfy the updated EntityDataGridRef interface

src/components/canary/organisms/item-grid/item-grid.tsx (complete rewrite)

• No longer builds on DataGrid molecule directly
• Uses createEntityDataGrid<Item> inside useMemo keyed on structural props
• Passes onNotesClick to createItemGridColumnDefs at factory creation time (via cellRendererParams)
• Maps ItemGridHandle ↔ EntityDataGridRef via combinedRef callback
• Preserves entire public API: ItemGridProps, ItemGridStaticConfig, ItemGridRuntimeConfig
• Adds ItemGridHandle (extends ItemGridEditingHandle + getGridApi())
• editingRef and gridRef both satisfied through the combined ref callback

src/components/canary/molecules/item-grid/item-grid-columns.tsx

• createItemGridColumnDefs now accepts options?: { onNotesClick?: (item: Item) => void }
• NotesCellRenderer reads onNotesClick from params.colDef?.cellRendererParams instead of params.context
• Notes column passes onNotesClick via cellRendererParams when provided

src/components/canary/organisms/item-grid/index.ts

• Removed export of useItemGridEditing types (file deleted)
• Added export of ItemGridHandle
• PendingChanges re-exported from entity-data-grid instead of old hook

src/components/canary/molecules/item-grid/item-grid-columns.tsx

• Changed SelectCellEditor import from ./select-cell-editor to canonical ../../atoms/grid/select/select-cell-editor
• Updated Order Method column cellEditorParams.values → cellEditorParams.options (canonical API)

src/components/canary/molecules/item-grid/item-grid-molecules.stories.tsx

• Updated SelectCellEditor import to canonical atom
• Updated story prop values → options

src/components/canary/organisms/item-grid/item-grid.stories.tsx

• Removed import type { AgGridReact } from 'ag-grid-react'
• Added import type { ItemGridHandle } from item-grid
• Changed gridRef = useRef<AgGridReact<Item>>(null) → useRef<ItemGridHandle>(null)
• Updated gridRef.current?.api?.setColumnsVisible(...) → gridRef.current?.getGridApi()?.setColumnsVisible(...)
• Updated gridRef.current?.api?.deselectAll() → gridRef.current?.getGridApi()?.deselectAll()
• Updated WithSearch play function: '1 item' → '1 of 12 items' (new count label format)

src/components/canary/organisms/item-grid/item-grid.test.tsx

• Updated 3 search-count assertions: '1 item' → '1 of 12 items' to match entity-data-grid count label behavior

Deleted files

src/components/canary/organisms/item-grid/use-item-grid-editing.ts

• Replaced by entity-data-grid/use-row-auto-publish.ts (same row-level auto-publish lifecycle)

src/components/canary/molecules/item-grid/select-cell-editor.tsx

• Canonical version is at atoms/grid/select/select-cell-editor.tsx

Behavioral Differences from Pre-refactor

Behavior	Before	After
Search count (no filter)	“12 items"	"12 items” (same)
Search count (active filter)	“1 item"	"1 of 12 items”
Height when no autoHeight	600px fixed	Fills parent container (flex)
Row selection checkboxes	Only when enableRowSelection: true	Always enabled (DataGrid default)
editingRef type	Ref<ItemGridEditingHandle>	Ref<ItemGridEditingHandle> (unchanged)
gridRef type	`RefObject<AgGridReact	null>`

The count label change (“1 item” → “1 of 12 items”) is a deliberate improvement that shows search context. Tests and the WithSearch story play function were updated to reflect this.
