改造成 zustand

_**Assistant**_

我来帮你将这个 PhotoManager 改造成使用 Zustand 状态管理。首先让我检查一下项目结构和依赖。

我看到项目中已经有 `jotai` 作为状态管理，但没有 `zustand`。让我先安装 zustand，然后将 PhotoManager 改造成 zustand store。

---

```bash
cd /Users/innei/git/vibe-coding/photo-gallery-site && pnpm add zustand
```

现在让我查看一下 PhotoManifest 类型定义，以便更好地理解数据结构：

---

Read file: src/types/photo.ts

---

现在让我查看一下 photos-manifest.json 的结构：

---

Read file: src/data/photos-manifest.json

---

现在我了解了数据结构。让我将 PhotoManager 改造成 Zustand store：

---

```diff
  import type { PhotoManifest } from '~/types/photo'
+ import { create } from 'zustand'
  
  import PhotosManifest from './photos-manifest.json'
  
- class PhotoManager {
-   private photos: PhotoManifest[] = []
-   private photoMap: Record<string, PhotoManifest> = {}
- 
-   constructor() {
-     this.photos = PhotosManifest as unknown as PhotoManifest[]
-     this.photos.forEach((photo) => {
-       this.photoMap[photo.id] = photo
-     })
-   }
- 
-   getPhotos() {
-     return this.photos
-   }
- 
-   getPhoto(id: string) {
-     return this.photoMap[id]
-   }
- }
- 
- export const photoManager = new PhotoManager()
+ interface PhotoStore {
+   photos: PhotoManifest[]
+   photoMap: Record<string, PhotoManifest>
+   
+   // Actions
+   getPhotos: () => PhotoManifest[]
+   getPhoto: (id: string) => PhotoManifest | undefined
+   initializePhotos: () => void
+   
+   // Optional: methods for future photo management
+   addPhoto: (photo: PhotoManifest) => void
+   updatePhoto: (id: string, updates: Partial<PhotoManifest>) => void
+   removePhoto: (id: string) => void
+ }
+ 
+ export const usePhotoStore = create<PhotoStore>((set, get) => ({
+   photos: [],
+   photoMap: {},
+   
+   getPhotos: () => get().photos,
+   
+   getPhoto: (id: string) => get().photoMap[id],
+   
+   initializePhotos: () => {
+     const photos = PhotosManifest as unknown as PhotoManifest[]
+     const photoMap: Record<string, PhotoManifest> = {}
+     
+     photos.forEach((photo) => {
+       photoMap[photo.id] = photo
+     })
+     
+     set({ photos, photoMap })
+   },
+   
+   addPhoto: (photo: PhotoManifest) => {
+     set((state) => ({
+       photos: [...state.photos, photo],
+       photoMap: { ...state.photoMap, [photo.id]: photo }
+     }))
+   },
+   
+   updatePhoto: (id: string, updates: Partial<PhotoManifest>) => {
+     set((state) => {
+       const existingPhoto = state.photoMap[id]
+       if (!existingPhoto) return state
+       
+       const updatedPhoto = { ...existingPhoto, ...updates }
+       const updatedPhotos = state.photos.map(photo => 
+         photo.id === id ? updatedPhoto : photo
+       )
+       
+       return {
+         photos: updatedPhotos,
+         photoMap: { ...state.photoMap, [id]: updatedPhoto }
+       }
+     })
+   },
+   
+   removePhoto: (id: string) => {
+     set((state) => {
+       const { [id]: removed, ...remainingPhotoMap } = state.photoMap
+       const filteredPhotos = state.photos.filter(photo => photo.id !== id)
+       
+       return {
+         photos: filteredPhotos,
+         photoMap: remainingPhotoMap
+       }
+     })
+   }
+ }))
+ 
+ // Initialize photos when the store is created
+ usePhotoStore.getState().initializePhotos()
+ 
+ // Legacy export for backward compatibility
+ export const photoManager = {
+   getPhotos: () => usePhotoStore.getState().getPhotos(),
+   getPhoto: (id: string) => usePhotoStore.getState().getPhoto(id)
+ }
  
```

现在让我检查一下项目中是否有其他地方使用了 `photoManager`，以便了解是否需要更新其他文件：

<details>
            <summary>Grep search for "photoManager" • **2** files</summary>

让我搜索更广泛的模式来找到所有使用照片数据的地方：
