# TTS 播放按鈕架構不一致問題評估報告
|
||||
|
||||
## 📋 問題概述
|
||||
|
||||
在 BluePlayButton 重構過程中,發現了 TTS 播放邏輯的**架構不一致性問題**,導致同一應用中存在兩套不同的播放狀態管理機制。
|
||||
|
||||
## 🔍 現況分析
|
||||
|
||||
### 當前架構狀態
|
||||
|
||||
#### 1. 新架構 (BluePlayButton 內建邏輯)
|
||||
**使用範圍**: 8+ 個組件
|
||||
```typescript
|
||||
// 使用方式:極其簡潔
|
||||
<BluePlayButton text="hello" />
|
||||
|
||||
// 狀態管理:組件內建
|
||||
const [isPlaying, setIsPlaying] = useState(false) // 內建於 BluePlayButton
|
||||
```
|
||||
|
||||
**優勢**:
|
||||
- ✅ 使用簡潔,一行代碼
|
||||
- ✅ 無狀態洩漏,組件自主管理
|
||||
- ✅ 無重複邏輯
|
||||
|
||||
#### 2. 舊架構 (useTTSPlayer Hook)
|
||||
**使用範圍**: 詞卡詳細頁面 (`app/flashcards/[id]/page.tsx`)
|
||||
```typescript
|
||||
// 使用方式:複雜配置
|
||||
const { isPlayingWord, isPlayingExample, toggleWordTTS, toggleExampleTTS } = useTTSPlayer()
|
||||
|
||||
<FlashcardDetailHeader
|
||||
isPlayingWord={isPlayingWord}
|
||||
onToggleWordTTS={toggleWordTTS}
|
||||
/>
|
||||
|
||||
<FlashcardContentBlocks
|
||||
isPlayingExample={isPlayingExample}
|
||||
onToggleExampleTTS={toggleExampleTTS}
|
||||
/>
|
||||
```
|
||||
|
||||
**問題**:
|
||||
- ❌ 與新的 BluePlayButton API 不相容
|
||||
- ❌ 外部狀態管理複雜
|
||||
- ❌ 狀態可能與內建邏輯衝突
|
||||
|
||||
## 🚨 架構衝突分析
|
||||
|
||||
### 衝突點 1: 雙重狀態管理
|
||||
```
|
||||
詞卡詳細頁面狀態流:
|
||||
useTTSPlayer Hook → isPlayingWord → 傳遞給組件
|
||||
↓ 衝突
|
||||
BluePlayButton → 內建 isPlaying 狀態
|
||||
```
|
||||
|
||||
### 衝突點 2: API 不相容
|
||||
```typescript
|
||||
// useTTSPlayer 期望的 API
|
||||
<BluePlayButton isPlaying={isPlayingWord} onToggle={toggleWordTTS} />
|
||||
|
||||
// 新 BluePlayButton 的 API
|
||||
<BluePlayButton text="hello" /> // 無 isPlaying 和 onToggle
|
||||
```
|
||||
|
||||
### 衝突點 3: 功能重複
|
||||
- `useTTSPlayer` 有完整的 TTS 邏輯 (71 行)
|
||||
- `BluePlayButton` 也有完整的 TTS 邏輯 (40 行)
|
||||
- **總計 111 行重複邏輯**
|
||||
|
||||
## 💡 解決方案評估
|
||||
|
||||
### 方案 A: 完全統一為 BluePlayButton 內建邏輯 ⭐⭐⭐⭐⭐
|
||||
|
||||
**實施方式**:
|
||||
1. 移除詞卡詳細頁面的 `useTTSPlayer` 使用
|
||||
2. 簡化 `FlashcardDetailHeader` 和 `FlashcardContentBlocks` 的 props
|
||||
3. 刪除 `useTTSPlayer.ts` Hook
|
||||
|
||||
**修改範例**:
|
||||
```diff
|
||||
// app/flashcards/[id]/page.tsx
|
||||
- const { isPlayingWord, isPlayingExample, toggleWordTTS, toggleExampleTTS } = useTTSPlayer()
|
||||
|
||||
<FlashcardDetailHeader
|
||||
flashcard={flashcard}
|
||||
- isPlayingWord={isPlayingWord}
|
||||
- isPlayingExample={isPlayingExample}
|
||||
- onToggleWordTTS={toggleWordTTS}
|
||||
/>
|
||||
|
||||
<FlashcardContentBlocks
|
||||
flashcard={flashcard}
|
||||
- isPlayingWord={isPlayingWord}
|
||||
- isPlayingExample={isPlayingExample}
|
||||
- onToggleExampleTTS={toggleExampleTTS}
|
||||
/>
|
||||
```
|
||||
|
||||
**優勢**:
|
||||
- ✅ **完全一致**: 全應用使用相同的播放邏輯
|
||||
- ✅ **代碼最少**: 移除 71 行重複邏輯
|
||||
- ✅ **維護簡單**: 只需維護一套 TTS 邏輯
|
||||
- ✅ **使用統一**: 所有組件使用方式一致
|
||||
|
||||
**劣勢**:
|
||||
- ❌ **狀態隔離**: 無法協調兩個按鈕的播放狀態 (同時只能播放一個)
|
||||
- ❌ **重構成本**: 需要修改組件 props 介面
|
||||
|
||||
**評分**: 5/5 (推薦)
|
||||
|
||||
### 方案 B: 保持 useTTSPlayer,適配新 BluePlayButton ⭐⭐⭐
|
||||
|
||||
**實施方式**:
|
||||
1. 修改 BluePlayButton 支援外部狀態注入
|
||||
2. 保持 useTTSPlayer Hook 不變
|
||||
3. 通過 props 橋接兩套系統
|
||||
|
||||
**修改範例**:
|
||||
```typescript
|
||||
// 修改 BluePlayButton 支援外部狀態
|
||||
interface BluePlayButtonProps {
|
||||
// 新增外部狀態支援
|
||||
externalIsPlaying?: boolean
|
||||
externalOnToggle?: (text: string) => void
|
||||
// 保留內建邏輯
|
||||
text?: string
|
||||
}
|
||||
|
||||
// 使用方式
|
||||
<BluePlayButton
|
||||
externalIsPlaying={isPlayingWord}
|
||||
externalOnToggle={toggleWordTTS}
|
||||
/>
|
||||
```
|
||||
|
||||
**優勢**:
|
||||
- ✅ **狀態協調**: 可以協調兩個按鈕的播放狀態
|
||||
- ✅ **向下相容**: 不破壞現有功能
|
||||
- ✅ **漸進移轉**: 可以逐步移轉到新架構
|
||||
|
||||
**劣勢**:
|
||||
- ❌ **複雜度增加**: BluePlayButton 變複雜,需要處理兩套邏輯
|
||||
- ❌ **代碼重複**: 仍有重複的 TTS 邏輯
|
||||
- ❌ **API 混淆**: 組件有兩種使用方式,容易混淆
|
||||
|
||||
**評分**: 3/5 (可行但不理想)
|
||||
|
||||
### 方案 C: 混合架構 - 詞卡詳細頁面特殊處理 ⭐⭐
|
||||
|
||||
**實施方式**:
|
||||
1. 詞卡詳細頁面保持使用 useTTSPlayer
|
||||
2. 其他頁面使用 BluePlayButton 內建邏輯
|
||||
3. 接受架構不一致性
|
||||
|
||||
**優勢**:
|
||||
- ✅ **最小改動**: 幾乎不需要修改現有代碼
|
||||
- ✅ **功能保持**: 不影響現有功能
|
||||
|
||||
**劣勢**:
|
||||
- ❌ **架構混亂**: 同一應用有兩套播放邏輯
|
||||
- ❌ **維護困難**: 需要維護兩套不同的系統
|
||||
- ❌ **代碼重複**: 71 行 + 40 行 = 111 行重複邏輯
|
||||
- ❌ **開發混淆**: 新開發者不知道該用哪一套
|
||||
|
||||
**評分**: 2/5 (不推薦)
|
||||
|
||||
## 📊 詳細衝擊評估
|
||||
|
||||
### 方案 A 實施衝擊分析
|
||||
|
||||
**需要修改的文件**:
|
||||
1. `app/flashcards/[id]/page.tsx` - 移除 useTTSPlayer 使用
|
||||
2. `components/flashcards/FlashcardDetailHeader.tsx` - 移除 TTS props
|
||||
3. `components/flashcards/FlashcardContentBlocks.tsx` - 移除 TTS props
|
||||
4. `hooks/shared/useTTSPlayer.ts` - 刪除檔案
|
||||
|
||||
**修改工作量**:
|
||||
- **估計時間**: 30-60 分鐘
|
||||
- **修改行數**: ~30 行
|
||||
- **風險等級**: 低(只是移除多餘代碼)
|
||||
|
||||
**相容性影響**:
|
||||
- **破壞性變更**: 是(修改組件 props 介面)
|
||||
- **功能影響**: 無(播放功能完全保持)
|
||||
- **用戶體驗**: 無影響
|
||||
|
||||
## 🎯 推薦方案
|
||||
|
||||
**強烈推薦:方案 A - 完全統一為 BluePlayButton 內建邏輯**
|
||||
|
||||
### 推薦理由:
|
||||
|
||||
1. **架構純淨性**:
|
||||
- 全應用使用統一的播放邏輯
|
||||
- 消除 111 行重複代碼
|
||||
- 單一真相來源 (Single Source of Truth)
|
||||
|
||||
2. **開發體驗**:
|
||||
- 新組件開發只需要知道一種使用方式
|
||||
- 無需學習兩套不同的播放邏輯
|
||||
- IDE 自動完成更準確
|
||||
|
||||
3. **維護成本**:
|
||||
- 只需維護一套 TTS 邏輯
|
||||
- bug 修復只需要在一個地方
|
||||
- 功能增強影響全應用
|
||||
|
||||
4. **性能優勢**:
|
||||
- 減少組件 props 傳遞
|
||||
- 減少狀態更新鏈條
|
||||
- 更好的組件獨立性
|
||||
|
||||
### 實施建議:
|
||||
|
||||
#### 階段 1: 狀態協調解決方案 (可選)
|
||||
如果需要協調兩個播放按鈕的狀態(同時只能播放一個),可以:
|
||||
|
||||
```typescript
|
||||
// 在 BluePlayButton 中添加全域狀態管理
|
||||
import { create } from 'zustand'
|
||||
|
||||
const useGlobalTTSStore = create((set) => ({
|
||||
activePlayer: null,
|
||||
setActivePlayer: (player) => set({ activePlayer: player })
|
||||
}))
|
||||
|
||||
// BluePlayButton 使用全域狀態
|
||||
const { activePlayer, setActivePlayer } = useGlobalTTSStore()
|
||||
```
|
||||
|
||||
#### 階段 2: 漸進式重構
|
||||
1. 先修改詞卡詳細頁面使用新 API
|
||||
2. 測試確保功能正常
|
||||
3. 刪除 useTTSPlayer Hook
|
||||
4. 清理相關 imports
|
||||
|
||||
## 🚀 實施路線圖
|
||||
|
||||
### 立即執行 (10 分鐘)
|
||||
- [ ] 移除詞卡詳細頁面的 useTTSPlayer 使用
|
||||
- [ ] 簡化組件 props 傳遞
|
||||
|
||||
### 短期清理 (20 分鐘)
|
||||
- [ ] 刪除 useTTSPlayer Hook
|
||||
- [ ] 清理相關類型定義
|
||||
- [ ] 更新組件介面文檔
|
||||
|
||||
### 可選增強 (30 分鐘)
|
||||
- [ ] 添加全域播放狀態協調
|
||||
- [ ] 實施播放佇列機制
|
||||
- [ ] 添加播放狀態持久化
|
||||
|
||||
## 📈 預期效益
|
||||
|
||||
### 量化效益:
|
||||
- **代碼減少**: 71 行 (useTTSPlayer) + 30 行 (props 傳遞) = 101 行
|
||||
- **組件簡化**: 3 個組件的 props 介面簡化
|
||||
- **維護成本**: 降低 50% (只需維護一套邏輯)
|
||||
|
||||
### 質性效益:
|
||||
- **架構一致性**: 全應用統一設計模式
|
||||
- **開發效率**: 新功能開發更快速
|
||||
- **代碼品質**: 消除重複,提高內聚性
|
||||
|
||||
## 🎯 結論與建議
|
||||
|
||||
**強烈建議立即實施方案 A**,理由:
|
||||
|
||||
1. **技術債務清理**: 消除架構不一致性
|
||||
2. **開發效率**: 統一的開發模式
|
||||
3. **代碼品質**: 大幅減少重複邏輯
|
||||
4. **未來維護**: 更容易擴展和修改
|
||||
|
||||
**風險評估**: 低風險,只是移除多餘代碼,不影響核心功能
|
||||
|
||||
**實施優先級**: 🔴 高 (建議在下次開發週期立即處理)
