@skmtc/gen-shadcn-select

Produce a React searchable-select component sourced from a GET list-response operation.

An operation generator. Useful when a form field references another resource (e.g., "office" on a contact form, sourced from GET /offices). Pairs with gen-shadcn-form's fields[].references enrichment.

What it generates

Per supported operation, a React select component:

export const OfficeSelect = ({ value, onChange }) => {
  const { data } = useGetOffices()
  return (
    <Combobox value={value} onChange={onChange}>
      {data.map(office => <ComboboxItem value={office.id}>{office.name}</ComboboxItem>)}
    </Combobox>
  )
}

Key decisions

Strict isSupported filter. Only GET operations that return a list response. The check imports isListResponse from @skmtc/gen-tanstack-query-supabase-zod:
```
import { isListResponse } from '@skmtc/gen-tanstack-query-supabase-zod'
isSupported: ({ operation }) => operation.method === 'get' && isListResponse(operation)
```
Cross-package utility import — a deliberate clone seam, not a refactoring target.
toPreviewModule and toMappingModule hooks. The entry declares two extra hooks beyond transform — toPreviewModule for IDE preview integration, toMappingModule for the form generator's references dispatch to know which select to reach for.
Combobox-based. The stock produces a searchable combobox, not a plain <select>. The shadcn/ui Combobox component is the target.

What to learn from it

Cross-generator helper sharing. The isListResponse utility is exported by gen-tanstack-query-supabase-zod and imported by this generator. Generator packages can ship reusable helpers, not just Entrys.
toMappingModule for cross-generator addressing. A second generator (gen-shadcn-form) reads the mapping module to discover "for this operationId, which select component should I embed?" The hook makes the lookup deterministic.
GET-list-response as a generator-specific shape. When your generator produces something meaningful only for a narrow operation shape, encode that in isSupported and let everything else fall through.

Common customizations when cloned

Swap Combobox for plain <select> or a different UI lib's equivalent.
Customize how items are labeled (the stock uses a name field if present; you may want to construct labels from multiple fields).
Add server-side filtering for very large lists (the stock loads everything client-side).
Change which transport hook is called (the stock pairs with Supabase; the fetch variant requires a swap).
