The project in the /packages/dashboard dir uses the following stack. Please make sure to use these in any solutions:

- React
- Shadcn UI & tailwind
- TanStack Query for data fetching, i.e. useQuery or useMutation. Not Apollo Client.
- TanStack router for any routing & navigation

## API Interaction

When creating useQuery or useMutation calls, use the following pattern as a guide:

```
import { api } from '@/graphql/api.js';
import { graphql } from '@/graphql/graphql.js';
import { useQuery } from '@tanstack/react-query';

const taxCategoriesDocument = graphql(`
    query TaxCategories($options: TaxCategoryListOptions) {
        taxCategories(options: $options) {
            items {
                id
                name
                isDefault
            }
        }
    }
`);

export function MyComponent() {
    const { data, isLoading, isPending, status } = useQuery({
        queryKey: ['taxCategories'],
        staleTime: 1000 * 60 * 5,
        queryFn: () =>
            api.query(taxCategoriesDocument, {
                options: {
                    take: 100,
                },
            }),
    });
}
```

When performing mutations, use this example as a guide:

```tsx
import { graphql } from '@/graphql/graphql.js';
import { api } from '@/graphql/api.js';
import { useMutation } from '@tanstack/react-query';

const createProductOptionsMutation = graphql(`
    mutation CreateOptionGroups($input: CreateProductOptionGroupInput!) {
        createProductOptionGroup(input: $input) {
            id
            name
            options {
                id
                code
                name
            }
        }
    }
`);

export function MyComponent() {
    // Note that explicit typings or generic params should _not_ be needed since the
    // type info will flow from the use of the `graphql` function, which uses gql.tada.
   const createOptionGroupMutation = useMutation({
        // note that variables are not passed at this point of declaration
        mutationFn: api.mutate(createProductOptionsMutation),
        onSuccess: () => {
            // whatever makes sense, e.g. show toast
        },
        onError: () => {
            // whatever makes sense
        },
    });


   // ... 

   function handleClick() {
        // variables are passed here
        createOptionGroupMutation.mutate({
            input: {
                // etc
            }
        })
   }

   //...

}

```

## Package Layout

The architecture of the dashboard is as follows:

- /src/lib contains shared code that is used across the dashboard.
- /src/app contains the routes and pages of the dashboard app.

In the "app" context, we try as much as possible to use the same patterns across all pages. Most of the app routes
are CRUD list/detail pages.

- A representative list page is [administrators.tsx](mdc:packages/dashboard/src/app/routes/_authenticated/_administrators/administrators.tsx)
- A representative detail page is [administrators_.$id.tsx](mdc:packages/dashboard/src/app/routes/_authenticated/_administrators/administrators_.$id.tsx)

These examples show the common components, hooks and patterns that should be used across the app.

In the "lib" context, we try to re-use components from the /src/lib/components dir, including preferring the Shadcn components
as much as possible from the /src/lib/components/ui dir.

## Forms

We have a special wrapper around the Shadcn react-hook-form components to make typical form controls
more concise:

```
 <FormFieldWrapper
    control={form.control}
    name="facetValueIds"
    label={<Trans>Facet values</Trans>}
    render={({ field }) => (
        <AssignedFacetValues facetValues={entity?.facetValues ?? []} {...field} />
    )}
/>
```

Please prefer this form over the raw Shadcn components where possible.

## Localization

Any labels or user-facing messages should use localization following this example:

```tsx
import { Trans, useLingui } from '@/lib/trans.js';


export function MyComponent() {

    const { i18n } = useLingui();

    const message = i18n.t('This is a localized string')

    return (
        <div>
            <Trans>This is a localized string in the markup</Trans>
        </div>
    )
}
```
