refactor(api): genres → src/api modules (Effort 1)

[chiptus]

Mechanical move of the genres feature from src/hooks/queries/genres to src/api/genres, adding queryOptions factories for the query hooks. No behavior change. Part of #52.

Manual verification

• Genre badges and the genre filter render on the Artists tab as before.
• In admin, add a genre and edit an artist's genres — both work.
• pnpm run lint && pnpm test && pnpm run build all pass.

PR Summary by Qodo

refactor(api): move genres queries/mutations to src/api/genres
✨ Enhancement 🧪 Tests 🕐 10-20 Minutes

Description

• Move the genres data-access hooks from hooks/queries into src/api/genres.
• Add shared query-key and queryOptions factories for consistent React Query usage.
• Update UI and tests to import genres hooks from the new module paths.

High-Level Assessment

The following are alternative approaches to this PR:

1. Add a src/api/genres/index.ts barrel

• ➕ Shorter, more stable imports (e.g., '@/api/genres') across the app
• ➕ Easier future reshuffles inside the module without touching call sites
• ➖ Adds an extra file/indirection that some teams prefer to avoid
• ➖ May encourage overly broad imports if not kept curated

2. Keep query keys as const values (no factory)

• ➕ Slightly simpler call sites (no parentheses)
• ➕ Less chance of accidentally creating variant keys (if only one key exists)
• ➖ Doesn’t scale as well when parameterized keys are added later
• ➖ Inconsistent with common TanStack Query key-factory patterns

Recommendation: Current approach is solid for a modular API layer: centralizing Genre types and using a query key factory + queryOptions improves consistency and sets up future parameterized keys. If this pattern will expand, consider adding a small barrel export (index.ts) to reduce repeated deep import paths and make future moves even more mechanical.

Add shared Genre type and genres query key factory

Invalidate genres cache via genresKeys factory

Add genresQuery() queryOptions factory and move keys/types

• Refactors genres fetching to use a dedicated genresQuery() that returns queryOptions, then consumes it from useGenresQuery(). Moves the query key definition into types.ts and tightens the fetch return type to Genre[].

1. Test mocks useGenres hook ✗ Dismissed 📜 Skill insight ▣ Testability

Description

GenreBadge.test.tsx mocks the internal useGenres hook module, which is an internal collaborator
rather than an external system boundary. This makes the test brittle to refactors (e.g., changing
which hook/component provides genres) while keeping behavior the same.

Code

src/components/GenreBadge.test.tsx[R4-6]

+import * as useGenresModule from "@/api/genres/useGenres";

-vi.mock("@/hooks/queries/genres/useGenres");
+vi.mock("@/api/genres/useGenres");

Evidence

PR Compliance ID 730914 forbids mocking internal collaborators. The changed test file directly mocks
the internal @/api/genres/useGenres module via vi.mock(...), which is not an external boundary
(e.g., network/Supabase).

src/components/GenreBadge.test.tsx[4-6]
Skill: tdd

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
The test mocks an internal module (`@/api/genres/useGenres`) instead of mocking only at a system boundary. This violates the testing compliance requirement and makes the test depend on implementation details.

## Issue Context
`GenreBadge` uses `useGenres()` internally. Instead of mocking that hook, prefer testing through the component’s observable behavior by providing the real hook with a `QueryClientProvider` and seeding React Query data (or mocking the Supabase client / network boundary).

## Fix Focus Areas

2. genresKeys.all uses arrow 📘 Rule violation ⚙ Maintainability

Description

genresKeys.all is implemented as an arrow function, but this rule requires named/exported
functions to use function declarations. Keeping arrow functions for named utilities can undermine
consistent refactor style and enforcement.

Code

src/api/genres/types.ts[R6-8]

+export const genresKeys = {
+  all: () => ["genres"] as const,
+};

Evidence

PR Compliance ID 721308 requires named/exported functions to be written as function declarations. In
src/api/genres/types.ts, genresKeys.all is an exported, reusable named function implemented as
an arrow function.

Rule 721308: Use function declarations for components and named functions
src/api/genres/types.ts[6-8]

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
`genresKeys.all` is a named/exported function implemented as an arrow function inside an exported object. The compliance rule requires function declaration syntax (`function Name(...) {}`) for named/exported functions.

## Issue Context
This module is part of the new `src/api/genres` structure; keep query key factories compliant while preserving the existing `genresKeys.all()` call sites.

Triage of Qodo's two findings — both pre-existing/codebase-consistent, no behavior impact; keeping #60 a mechanical move:

1. genresKeys.all arrow function (rule 721308). Every key factory in the codebase uses this exact shape — festivalsKeys.all, editionsKeys.all, setsKeys all do all: () => [...] as const. The CLAUDE.md "use function declarations" rule targets components and standalone named functions, not arrow values inside a key-factory object (a function declaration can't be an object property anyway). Converting only genres would make it inconsistent with every other feature's keys. Declining to keep the pattern uniform — switching key factories to method shorthand would be a codebase-wide change, not this slice.

2. Test mocks internal useGenres (tdd skill insight). Pre-existing — the diff shows this PR only repointed the existing vi.mock(...) path (@/hooks/queries/genres/useGenres → @/api/genres/useGenres); the internal-collaborator mock predates the move. Reworking GenreBadge's test to render through a QueryClientProvider (instead of mocking the hook) is a genuine test-quality improvement, but it's its own change, out of scope for a mechanical move.

No code changes here.

Do we need this hook?

[chiptus]

Collapsed it in 0a8a77f — removed the useGenres() adapter and pointed its two consumers (GenreBadge, FilterSortControls) at useGenresQuery() directly.

useGenresQuery stays: AddArtistDialog and GenresCell consume it directly, and genresQuery() remains as the loader-ready options factory. Typecheck + the 9 GenreBadge tests pass.
