# Resource Page
The `ResourcePage` component is the primary generic shell for any CRUD list page. It composes layout, table, dialog, and state management into a single, reusable component.
---
## Files
| File | Description |
|---|---|
| `shared/data-view/resource-page/resource-page.tsx` | The React component |
| `shared/data-view/resource-page/use-resource-page.ts` | The state/logic hook |
| `shared/data-view/resource-page/index.ts` | Public exports |
---
## `<ResourcePage>` Component
### Props
```ts
type ResourcePageProps<TClient extends ResourcePageClient> = {
// Required
title: string // Used for the "Add" button label and dialog title
routeKey: string // React Query cache key (e.g. CUSTOMER_ROUTES.INDEX)
getClient: (api: ApiInstance) => TClient // Selects the domain client from the API
columns: // Column definitions or a factory receiving helpers
| ColumnDef<ResourceItem<TClient>>[]
| ((helpers: ResourcePageColumnHelpers<TClient>) => ColumnDef<ResourceItem<TClient>>[])
renderForm: (props: ResourceFormProps<TClient>) => React.ReactNode
// Optional
pageTitle?: string // Heading text (defaults to undefined)
queryOptions?: Omit<UseQueryOptions<...>, "queryKey" | "queryFn">
}
```
### `ResourcePageColumnHelpers`
Passed to the `columns` callback, providing three pre-wired helpers:
| Helper | Type | Description |
|---|---|---|
| `actionsColumn(options?)` | `ColumnDef` | Pre-built Edit + Delete dropdown column |
| `openEdit(row)` | `(row: TItem) => void` | Opens dialog with row pre-filled |
| `deleteItem(id)` | `(id: string) => Promise<unknown>` | Deletes with toast + confirmation |
The `actionsColumn` factory (`createActionsColumn`) can be further customized:
```ts
actionsColumn({
onEdit: (row) => customOpen(row),
onDelete: async (row) => {
// completely override delete behavior
},
})
```
### `ResourceFormProps`
Passed to the `renderForm` callback:
| Prop | Type | Description |
|---|---|---|
| `resourceId` | `string \| null` | `null` on create; the item's `id` string on edit |
| `initialData` | `TItem \| null` | The full row object on edit (from the table's in-memory state) |
| `onSuccess` | `() => void` | Call this after a successful mutation to refresh the list |
---
## `useResourcePage` Hook
Encapsulates all state and logic. Returned by `ResourcePage` internally but also exported for use in custom page layouts.
```ts
const page = useResourcePage<MyClient>({ routeKey, getClient, queryOptions })
```
### Returns
| Key | Type | Description |
|---|---|---|
| `data` | `CrudListResponse<TClient>` | Raw API response |
| `isLoading` | `boolean` | True while initial fetch is in progress |
| `pagination` | `DataViewPaginationState` | `{ page, pageSize, pageCount, total }` |
| `sorting` | `DataViewSorting` | Current sort state |
| `handleChange` | `(event: DataViewChangeEvent) => void` | Handles pagination and sort events |
| `invalidateQuery` | `() => void` | Busts the React Query cache for the current query key |
| `selectedItem` | `TItem \| null` | The row being edited (populated by `openEdit`) |
| `openEdit(row)` | fn | Sets `selectedItem` and opens dialog |
| `openCreate()` | fn | Clears `selectedItem` and opens dialog |
| `openDialog(id?)` | fn | Low-level dialog open (sets `?dialog=true&resourceId=id` in URL) |
| `closeDialog()` | fn | Closes dialog (removes URL params) |
| `isDialogOpen` | `boolean` | Current dialog open state |
| `dialogResourceId` | `string \| null` | Current resource ID from URL |
| `deleteItem(id)` | `(id: string) => Promise<unknown>` | Mutation that destroys a resource |
| `actionsColumn(options?)` | fn | Generates the actions `ColumnDef` |
| `client` | `TClient` | The domain API client |
| `api` | `ApiInstance` | Full authenticated API object |
---
## `FormDialog` — URL-Driven Dialog
`FormDialog` and its companion hook `useFormDialog` manage dialog open/close state **via URL query parameters**:
| URL param | Value | Meaning |
|---|---|---|
| `dialog` | `true` / absent | Dialog open/closed |
| `resourceId` | string / absent | ID of the item being edited |
This means sharing or refreshing the URL with `?dialog=true&resourceId=5` will reopen the dialog on the same item (as long as `initialData` is in memory—see [Enhancement Plan](./enhancement-plan.md)).
### `useFormDialog`
```ts
const { isOpen, resourceId, open, close } = useFormDialog()
open("5") // opens dialog in edit mode
open() // opens dialog in create mode
close() // closes dialog, clears resourceId
```
---
## `ConfirmDialog` — Imperative Async Confirm
`ConfirmDialog` is a **singleton store-driven dialog** mounted once in the root layout. It exposes an imperative `confirm()` function:
```ts
import { confirm } from "@/shared/components/confirm-dialog"
const ok = await confirm({
title: "Delete this item?",
description: "This action cannot be undone.",
confirmLabel: "Delete",
variant: "destructive", // shows destructive styling + trash icon
})
if (ok) { /* proceed */ }
```
> **Important:** `<ConfirmDialog />` must be rendered once in the root layout. If it is not mounted, `confirm()` will open a dialog that is never displayed.
---
## `createActionsColumn`
A standalone factory for generating the standard Edit + Delete column:
```ts
import { createActionsColumn } from "@/shared/data-view/table-view"
createActionsColumn<MyItem>({
onEdit: (row) => openEdit(row),
onDelete: async (row) => {
const confirmed = await confirm({ ... })
if (confirmed) await deleteItem(String(row.id))
},
})
```

## Component Tree
```
<ResourcePage>
└─ <DashboardPage header={...} title={pageTitle}>
├─ <DashboardHeader>
│ └─ <FormDialog title={title}> ← "Add Customer" button + Dialog shell
│ └─ renderForm(resourceId) ← Feature-specific form
└─ <Card>
└─ <CardContent>
└─ <DataTable columns data pagination sorting onChange isLoading>
├─ <DataViewProvider> ← Shares state via context
├─ TanStack Table (manual pagination + sorting)
├─ Skeleton rows while loading
└─ <DataViewPagination> ← Page controls + rows-per-page
```
