## 🎯 7種複習模式詳細規格
|
||
|
||
### 1. 翻卡記憶 (FlipMemoryTest)
|
||
|
||
**學習目標**: 詞彙記憶強化，培養語感
|
||
**交互方式**: 3D翻卡動畫 + 信心度評估
|
||
|
||
**技術實現**：
|
||
```typescript
|
||
interface FlipMemoryTestProps {
|
||
cardData: ReviewCardData
|
||
onConfidenceSubmit: (level: number) => void
|
||
onReportError: () => void
|
||
disabled?: boolean
|
||
}
|
||
|
||
const FlipMemoryTest: React.FC<FlipMemoryTestProps> = ({ cardData, onConfidenceSubmit }) => {
|
||
const [isFlipped, setIsFlipped] = useState(false)
|
||
const [selectedConfidence, setSelectedConfidence] = useState<number | null>(null)
|
||
const [cardHeight, setCardHeight] = useState<number>(400)
|
||
|
||
// 動態高度調整算法
|
||
const updateCardHeight = useCallback(() => {
|
||
const minHeightByScreen = window.innerWidth <= 480 ? 300 :
|
||
window.innerWidth <= 768 ? 350 : 400
|
||
const backHeight = backRef.current?.scrollHeight || 0
|
||
const finalHeight = Math.max(minHeightByScreen, backHeight)
|
||
setCardHeight(finalHeight)
|
||
}, [])
|
||
}
|
||
```
|
||
|
||
**特色功能**：
|
||
- **3D 翻轉動畫**: CSS transform3d 實現流暢翻卡
|
||
- **響應式高度**: 根據內容動態調整卡片高度
|
||
- **信心度評估**: 1-5級信心度影響下次復習間隔
|
||
|
||
### 2. 詞彙選擇 (VocabChoiceTest)
|
||
|
||
**學習目標**: 詞彙理解驗證
|
||
**交互方式**: 4選1選擇題
|
||
|
||
**演算法**：
|
||
```typescript
|
||
// 干擾項生成演算法
|
||
const generateDistractors = (correctAnswer: string, allCards: FlashCard[]): string[] => {
|
||
const samePOS = allCards.filter(card =>
|
||
card.partOfSpeech === correctAnswer.partOfSpeech &&
|
||
card.word !== correctAnswer.word
|
||
)
|
||
|
||
const similarCEFR = allCards.filter(card =>
|
||
card.cefr === correctAnswer.cefr &&
|
||
card.word !== correctAnswer.word
|
||
)
|
||
|
||
// 混合策略：50% 同詞性 + 50% 同難度
|
||
const distractors = [
|
||
...sampleRandom(samePOS, 2),
|
||
...sampleRandom(similarCEFR, 2)
|
||
].slice(0, 3)
|
||
|
||
return shuffle([correctAnswer.word, ...distractors.map(d => d.word)])
|
||
}
|
||
```
|
||
|
||
### 3. 聽力測驗 (VocabListeningTest + SentenceListeningTest)
|
||
|
||
**學習目標**: 聽力理解 + 發音識別
|
||
**交互方式**: 語音播放 + 選擇作答
|
||
|
||
**TTS 整合**：
|
||
```typescript
|
||
// 統一使用 BluePlayButton 內建邏輯
|
||
const VocabListeningTest = ({ cardData, options, onAnswer }) => {
|
||
const audioArea = (
|
||
<div className="bg-gray-50 rounded-lg p-4">
|
||
<h3 className="font-semibold text-gray-900 mb-2">發音</h3>
|
||
<div className="flex items-center gap-3">
|
||
<span className="text-gray-700">{cardData.pronunciation}</span>
|
||
<BluePlayButton
|
||
text={cardData.word}
|
||
size="md"
|
||
title="播放單詞"
|
||
/>
|
||
</div>
|
||
</div>
|
||
)
|
||
}
|
||
```
|
||
|
||
### 4. 填空測驗 (SentenceFillTest)
|
||
|
||
**學習目標**: 語境理解 + 詞彙運用
|
||
**交互方式**: 輸入式作答 + 智能提示
|
||
|
||
**核心實現**：
|
||
```typescript
|
||
const SentenceFillTest = ({ cardData, onAnswer }) => {
|
||
const [userAnswer, setUserAnswer] = useState('')
|
||
|
||
// 答案驗證邏輯
|
||
const checkAnswer = useCallback((answer: string): boolean => {
|
||
const normalizedAnswer = answer.trim().toLowerCase()
|
||
const correctAnswer = cardData.word.toLowerCase()
|
||
|
||
// 支援多種正確答案格式
|
||
const acceptableAnswers = [
|
||
correctAnswer,
|
||
correctAnswer.replace(/s$/, ''), // 複數形式
|
||
correctAnswer.replace(/ed$/, ''), // 過去式
|
||
correctAnswer.replace(/ing$/, ''), // 進行式
|
||
]
|
||
|
||
return acceptableAnswers.includes(normalizedAnswer)
|
||
}, [cardData.word])
|
||
}
|
||
```
|
||
|
||
### 5. 語句重組 (SentenceReorderTest)
|
||
|
||
**學習目標**: 語法結構理解
|
||
**交互方式**: 拖拉排序
|
||
|
||
**技術挑戰**：
|
||
```typescript
|
||
// React DnD 實現拖拉排序
|
||
const SentenceReorderTest = ({ cardData, onAnswer }) => {
|
||
const [words, setWords] = useState<string[]>([])
|
||
|
||
// 打散演算法
|
||
const shuffleWords = useCallback((sentence: string): string[] => {
|
||
const punctuation = /[.,!?;:]/g
|
||
const cleanSentence = sentence.replace(punctuation, '')
|
||
const wordsArray = cleanSentence.split(' ')
|
||
return shuffle(wordsArray)
|
||
}, [])
|
||
|
||
// 答案驗證演算法
|
||
const validateOrder = (reorderedWords: string[]): boolean => {
|
||
const userSentence = reorderedWords.join(' ')
|
||
const correctSentence = cardData.example
|
||
return normalizeSentence(userSentence) === normalizeSentence(correctSentence)
|
||
}
|
||
}
|
||
```
|
||
|
||
## 🧠 Zustand Store 架構詳解
|
||
|
||
### Store 分工架構
|
||
|
||
```
|
||
store/review/
|
||
├── useReviewSessionStore.ts # 複習會話核心狀態
|
||
├── useTestQueueStore.ts # 智能測試佇列管理
|
||
├── useTestResultStore.ts # 測試結果統計
|
||
├── useReviewDataStore.ts # 複習資料載入
|
||
└── useReviewUIStore.ts # UI 狀態管理
|
||
```
|
||
|
||
### 3.1 TestQueueStore - 智能佇列管理
|
||
|
||
**核心狀態**：
|
||
```typescript
|
||
interface TestQueueState {
|
||
testItems: TestItem[] // 測試項目陣列
|
||
currentTestIndex: number // 當前測試索引
|
||
skippedTests: Set<string> // 跳過的測試集合
|
||
priorityQueue: TestItem[] // 智能優先級佇列
|
||
}
|
||
```
|
||
|
||
**核心演算法 - 智能優先級計算**：
|
||
```typescript
|
||
function calculateTestPriority(test: TestItem): number {
|
||
let priority = 0
|
||
const now = Date.now()
|
||
|
||
// 1. 未嘗試的測驗 = 100分 (最高優先級)
|
||
if (!test.isCompleted && !test.isSkipped && !test.isIncorrect) {
|
||
priority = 100
|
||
}
|
||
// 2. 答錯的測驗 = 20分 (需要重複練習)
|
||
else if (test.isIncorrect) {
|
||
priority = 20
|
||
// 最近答錯的稍微降低優先級，避免連續重複
|
||
if (test.lastAttemptAt && (now - test.lastAttemptAt) < 60000) {
|
||
priority = 15
|
||
}
|
||
}
|
||
// 3. 跳過的測驗 = 10分 (最低優先級)
|
||
else if (test.isSkipped) {
|
||
priority = 10
|
||
// 跳過時間越久，優先級稍微提高
|
||
if (test.skippedAt) {
|
||
const hours = (now - test.skippedAt) / (1000 * 60 * 60)
|
||
priority += Math.min(hours * 0.5, 5)
|
||
}
|
||
}
|
||
|
||
return priority
|
||
}
|
||
```
|
||
|
||
**佇列重排序機制**：
|
||
```typescript
|
||
reorderByPriority: () => set(state => {
|
||
const reorderedItems = [...state.testItems]
|
||
.map(item => ({ ...item, priority: calculateTestPriority(item) }))
|
||
.sort((a, b) => {
|
||
// 1. 優先級分數高的在前
|
||
if (b.priority !== a.priority) {
|
||
return b.priority - a.priority
|
||
}
|
||
// 2. 相同優先級時，按原始順序
|
||
return a.order - b.order
|
||
})
|
||
|
||
// 更新當前測試索引
|
||
const currentTest = state.testItems[state.currentTestIndex]
|
||
const newCurrentIndex = reorderedItems.findIndex(item =>
|
||
item.id === currentTest?.id
|
||
)
|
||
|
||
return {
|
||
testItems: reorderedItems,
|
||
currentTestIndex: Math.max(0, newCurrentIndex)
|
||
}
|
||
})
|
||
```
|
||
|
||
### 3.2 ReviewSessionStore - 會話狀態管理
|
||
|
||
**核心職責**: 管理複習會話的生命週期
|
||
|
||
```typescript
|
||
interface ReviewSessionState {
|
||
// 會話狀態
|
||
mounted: boolean // 組件掛載狀態
|
||
isLoading: boolean // 載入狀態
|
||
error: string | null // 錯誤訊息
|
||
|
||
// 當前卡片狀態
|
||
currentCard: ExtendedFlashcard | null // 當前複習的詞卡
|
||
currentCardIndex: number // 當前卡片索引
|
||
|
||
// 複習模式
|
||
mode: ReviewMode // 當前複習模式
|
||
isAutoSelecting: boolean // 自動選擇詞卡中
|
||
|
||
// 會話控制
|
||
showNoDueCards: boolean // 顯示無詞卡狀態
|
||
showComplete: boolean // 顯示完成狀態
|
||
|
||
// 統計數據
|
||
completedCards: number // 已完成詞卡數
|
||
correctAnswers: number // 正確答案數
|
||
sessionStartTime: Date | undefined // 會話開始時間
|
||
}
|
||
```
|
||
|
||
### 3.3 ReviewDataStore - 資料管理
|
||
|
||
**資料載入策略**：
|
||
```typescript
|
||
const loadDueCards = async () => {
|
||
try {
|
||
setLoadingCards(true)
|
||
setLoadingError(null)
|
||
console.log('🔍 開始載入到期詞卡...')
|
||
|
||
const apiResult = await flashcardsService.getDueFlashcards(50)
|
||
console.log('📡 API回應結果:', apiResult)
|
||
|
||
if (apiResult.success && apiResult.data && apiResult.data.length > 0) {
|
||
const cards = apiResult.data
|
||
console.log('✅ 載入後端API數據成功:', cards.length, '張詞卡')
|
||
|
||
setDueCards(cards)
|
||
setShowNoDueCards(false)
|
||
} else {
|
||
console.log('📭 沒有到期的詞卡')
|
||
setDueCards([])
|
||
setShowNoDueCards(true)
|
||
}
|
||
} catch (error) {
|
||
const errorMessage = error instanceof Error ? error.message : '載入失敗'
|
||
console.error('❌ 載入詞卡時發生錯誤:', errorMessage)
|
||
setLoadingError(errorMessage)
|
||
setShowNoDueCards(true)
|
||
} finally {
|
||
setLoadingCards(false)
|
||
}
|
||
}
|
||
```
|
||
|
||
## 📱 組件設計模式
|
||
|
||
### 4.1 容器-展示組件模式
|
||
|
||
**ReviewRunner (容器組件)**：
|
||
```typescript
|
||
export const ReviewRunner = () => {
|
||
// 狀態管理
|
||
const { currentCard, currentTestIndex } = useReviewSessionStore()
|
||
const { testItems, markTestCompleted } = useTestQueueStore()
|
||
const { updateScore, recordResult } = useTestResultStore()
|
||
|
||
// 業務邏輯處理
|
||
const handleAnswer = useCallback(async (answer: string) => {
|
||
const isCorrect = validateAnswer(answer, currentCard, currentMode)
|
||
updateScore(isCorrect)
|
||
await recordResult({ /* params */ })
|
||
markTestCompleted(currentTestIndex)
|
||
}, [currentCard, currentMode])
|
||
|
||
// 動態組件渲染
|
||
const renderTestContent = () => {
|
||
const Component = TEST_COMPONENTS[currentMode]
|
||
return <Component cardData={currentCard} onAnswer={handleAnswer} />
|
||
}
|
||
|
||
return renderTestContent()
|
||
}
|
||
```
|
||
|
||
**測驗組件 (展示組件)**：
|
||
```typescript
|
||
// 純UI組件，不涉及複雜業務邏輯
|
||
export const FlipMemoryTest: React.FC<FlipMemoryTestProps> = ({
|
||
cardData,
|
||
onConfidenceSubmit,
|
||
disabled = false
|
||
}) => {
|
||
const [isFlipped, setIsFlipped] = useState(false)
|
||
const [selectedConfidence, setSelectedConfidence] = useState<number | null>(null)
|
||
|
||
// 只處理UI狀態和簡單交互
|
||
const handleFlip = () => setIsFlipped(!isFlipped)
|
||
|
||
return (
|
||
<div className="flip-card" onClick={handleFlip}>
|
||
{/* UI 渲染邏輯 */}
|
||
</div>
|
||
)
|
||
}
|
||
```
|
||
|
||
### 4.2 共享組件設計
|
||
|
||
**統一的測驗介面**：
|
||
```typescript
|
||
// 基礎測驗組件介面
|
||
export interface BaseReviewProps {
|
||
cardData: ReviewCardData
|
||
onAnswer: (answer: string) => void
|
||
onReportError: () => void
|
||
disabled?: boolean
|
||
}
|
||
|
||
// 選擇題擴展介面
|
||
export interface ChoiceTestProps extends BaseReviewProps {
|
||
options: string[]
|
||
}
|
||
|
||
// 信心度測驗介面
|
||
export interface ConfidenceTestProps extends BaseReviewProps {
|
||
onConfidenceSubmit: (level: number) => void
|
||
}
|
||
```
|
||
|
||
**可重用UI組件庫**：
|
||
```typescript
|
||
// 測驗相關組件
|
||
export { TestHeader } from './shared' // 標準化測驗標題
|
||
export { ChoiceGrid } from './shared' // 4選1選項網格
|
||
export { ConfidenceLevel } from './shared' // 信心度選擇器
|
||
export { TestResultDisplay } from './shared' // 測驗結果展示
|
||
export { BluePlayButton } from '@/shared' // 統一播放按鈕
|
||
|
||
// 導航和控制組件
|
||
export { SmartNavigationController } from './shared' // 智能導航
|
||
export { ProgressBar } from './shared' // 進度條
|
||
export { ErrorReportButton } from './shared' // 錯誤回報
|
||
```
|
||
|
||
## 🔄 資料流和狀態同步機制
|
||
|
||
### 5.1 完整資料流程
|
||
|
||
```mermaid
|
||
sequenceDiagram
|
||

|
||

|
||
participant ReviewData
|
||
participant TestQueue
|
||
participant ReviewRunner
|
||

|
||
|
||
User->>ReviewPage: 進入複習頁面
|
||
ReviewPage->>ReviewData: loadDueCards()
|
||
ReviewData->>Backend: getDueFlashcards(50)
|
||
Backend-->>ReviewData: 詞卡資料
|
||
ReviewData-->>TestQueue: 觸發佇列初始化
|
||
TestQueue->>TestQueue: generateTestItems()
|
||
TestQueue-->>ReviewRunner: 提供測驗項目
|
||
ReviewRunner-->>User: 顯示測驗界面
|
||
|
||
User->>ReviewRunner: 提交答案
|
||
ReviewRunner->>TestResult: recordAnswer()
|
||
ReviewRunner->>Backend: 同步結果
|
||
ReviewRunner->>TestQueue: markCompleted()
|
||
TestQueue->>TestQueue: reorderByPriority()
|
||
TestQueue-->>ReviewRunner: 下一個測驗
|
||
```
|
||
|
||
### 5.2 狀態同步策略
|
||
|
||
**響應式狀態同步**：
|
||
```typescript
|
||
// 監聽測試佇列變化，自動更新當前卡片
|
||
useEffect(() => {
|
||
if (testItems.length > 0 && dueCards.length > 0) {
|
||
const currentTestItem = testItems.find(item => item.isCurrent)
|
||
if (currentTestItem) {
|
||
const card = dueCards.find(c => c.id === currentTestItem.cardId)
|
||
if (card) {
|
||
setCurrentCard(card)
|
||
setMode(currentTestItem.testType)
|
||
}
|
||
}
|
||
}
|
||
}, [testItems, dueCards, setCurrentCard, setMode])
|
||
```
|
||
|
||
**跨Store協作機制**：
|
||
```typescript
|
||
// TestQueue 完成時觸發 ReviewSession 狀態更新
|
||
markTestCompleted: (testIndex) => {
|
||
const completedItem = get().testItems[testIndex]
|
||
|
||
// 1. 更新本Store狀態
|
||
set(state => ({
|
||
testItems: state.testItems.map((item, index) =>
|
||
index === testIndex ? { ...item, isCompleted: true } : item
|
||
),
|
||
completedTests: state.completedTests + 1
|
||
}))
|
||
|
||
// 2. 通知其他Store
|
||
const { incrementCompleted } = useTestResultStore.getState()
|
||
incrementCompleted()
|
||
|
||
// 3. 檢查是否完成所有測試
|
||
const updatedState = get()
|
||
if (updatedState.completedTests >= updatedState.totalTests) {
|
||
const { setShowComplete } = useReviewDataStore.getState()
|
||
setShowComplete(true)
|
||
}
|
||
}
|
||
```
|
||
|
||
## 🎛️ API 設計規格
|
||
|
||
### 6.1 服務層統一介面
|
||
|
||
**ReviewService 核心方法**：
|
||
```typescript
|
||
export class ReviewService {
|
||
// 載入到期詞卡
|
||
static async loadDueCards(limit = 50): Promise<ExtendedFlashcard[]> {
|
||
const result = await flashcardsService.getDueFlashcards(limit)
|
||
if (result.success && result.data) {
|
||
return result.data.map(card => ({
|
||
...card,
|
||
// 擴展資料：添加複習相關欄位
|
||
lastReviewDate: card.lastReviewDate || null,
|
||
nextReviewDate: card.nextReviewDate || null,
|
||
reviewCount: card.reviewCount || 0,
|
||
masteryLevel: card.masteryLevel || 0
|
||
}))
|
||
}
|
||
throw new Error(result.error || '載入詞卡失敗')

const result = await flashcardsService.recordTestCompletion({
|
||
flashcardId: params.flashcardId,

}
|
||
```
|
||
|
||
### 6.2 後端API接口規格
|
||
|
||
**核心API端點**：
|
||
|
||
```typescript
|
||
// GET /api/flashcards/due?limit=50
|
||
interface DueCardsResponse {
|
||
success: boolean
|
||
data: ExtendedFlashcard[]
|
||
total: number
|
||
metadata: {
|
||
userLevel: string
|
||
lastUpdate: string
|
||
nextScheduledReview: string
|
||
}
|
||
}
|
||
|
||
// POST /api/flashcards/test-completion
|
||
interface TestCompletionRequest {
|
||
flashcardId: string
|
||
testType: ReviewMode
|
||
isCorrect: boolean
|
||
userAnswer?: string
|
||
confidenceLevel?: number
|

|
||
}
|
||
```
|
||
|
||
## 🧮 CEFR 智能分配演算法
|
||
|
||
### 7.1 基於 CEFR 的測驗分配
|
||
|
||
**核心演算法**：
|
||
```typescript
|
||
export const getReviewTypesByCEFR = (userCEFR: string, wordCEFR: string): ReviewMode[] => {
|
||
const userLevel = cefrToNumeric(userCEFR) // A1=1, A2=2, ..., C2=6
|
||
const wordLevel = cefrToNumeric(wordCEFR)
|
||
const difficulty = wordLevel - userLevel // 難度差距
|
||
|
||
// A1初學者：只用最基礎的模式
|
||
if (userCEFR === 'A1') {
|
||
return ['flip-memory', 'vocab-choice']
|
||
}
|
||
|
||
// 根據難度差距分配測驗類型
|
||
if (difficulty <= -2) {
|
||
// 詞彙比用戶等級低很多：練習語句運用
|
||
return ['sentence-reorder', 'sentence-fill', 'sentence-listening']
|
||
} else if (difficulty >= -1 && difficulty <= 1) {
|
||
// 詞彙與用戶等級相當：全面練習
|
||
return ['sentence-fill', 'sentence-reorder', 'vocab-choice', 'vocab-listening']
|
||
} else if (difficulty >= 2) {
|
||
// 詞彙比用戶等級高：基礎認識即可
|
||
return ['flip-memory', 'vocab-choice']
|
||
}
|
||
|
||
// 預設配置
|
||
return ['flip-memory', 'vocab-choice', 'sentence-fill']
|
||
}
|
||
```
|
||
|
||
### 7.2 動態難度調整
|
||
|
||
**個人化學習路徑**：
|
||
```typescript
|
||
interface AdaptiveLearningEngine {
|
||
// 分析用戶學習模式
|
||
analyzeUserPattern(history: TestResult[]): {
|
||
strongModes: ReviewMode[] // 用戶擅長的模式
|
||
weakModes: ReviewMode[] // 需要加強的模式
|
||
averageResponseTime: number // 平均回應時間
|
||
accuracyByMode: Record<ReviewMode, number> // 各模式正確率
|
||
}
|
||
|
||
// 動態調整測驗分配
|
||
adjustTestAllocation(
|
||
standardTypes: ReviewMode[],
|
||
userPattern: UserPattern
|
||
): ReviewMode[] {
|
||
return standardTypes.map(type => {
|
||
// 如果用戶在某個模式表現較差，增加練習
|
||
if (userPattern.weakModes.includes(type)) {
|
||
return [type, type] // 重複練習
|
||
}
|
||
return type
|
||
}).flat()
|
||
}
|
||
}
|
||
```
|
||
|
||
## 🎨 用戶體驗設計
|
||
|
||
### 8.1 智能導航系統
|
||
|
||
**SmartNavigationController**：
|
||
```typescript
|
||
export const SmartNavigationController = ({
|
||
hasAnswered, // 是否已答題
|
||
canSkip, // 是否可跳過
|
||
disabled, // 是否禁用
|
||
onSkip, // 跳過回調
|
||
onContinue // 繼續回調
|
||
}) => {
|
||
const navigationConfig = {
|
||
// 未答題狀態：顯示跳過按鈕
|
||
unanswered: () => (
|
||
<div className="flex justify-center gap-4">
|
||
{canSkip && (
|
||
<button onClick={onSkip} disabled={disabled}
|
||
className="px-6 py-3 border border-gray-300 text-gray-700 rounded-lg hover:bg-gray-50">
|
||
跳過 ⏭️
|
||
</button>
|
||
)}
|
||
</div>
|
||
),
|
||
|
||
// 已答題狀態：顯示繼續按鈕
|
||
answered: () => (
|
||
<div className="flex justify-center">
|
||
<button onClick={onContinue}
|
||
className="px-6 py-3 bg-blue-600 text-white rounded-lg hover:bg-blue-700 transition-colors">
|
||
繼續 ▶️
|
||
</button>
|
||
</div>
|
||
)
|
||
}
|
||
|
||
return hasAnswered ? navigationConfig.answered() : navigationConfig.unanswered()
|
||
}
|
||
```
|
||
|
||
### 8.2 進度追蹤和視覺反饋
|
||
|
||
**ProgressTracker 設計**：
|
||
```typescript
|
||
export const ProgressTracker = ({
|
||
completedTests,
|
||
totalTests,
|
||
onShowTaskList
|
||
}) => {
|
||
const progressPercentage = totalTests > 0 ? (completedTests / totalTests) * 100 : 0
|
||
|
||
return (
|
||
<div className="mb-8">
|
||
<div className="flex justify-between items-center mb-3">
|
||
<span className="text-sm font-medium text-gray-900">學習進度</span>
|
||
<button
|
||
onClick={onShowTaskList}
|
||
className="text-sm text-gray-600 hover:text-blue-600 transition-colors"
|
||
>
|
||
測驗: {completedTests}/{totalTests} 📋
|
||
</button>
|
||
</div>
|
||
|
||
{/* 動畫進度條 */}
|
||
<div className="w-full bg-gray-200 rounded-full h-3 cursor-pointer" onClick={onShowTaskList}>
|
||
<div
|
||
className="bg-blue-500 h-3 rounded-full transition-all duration-700 ease-out"
|
||
style={{ width: `${progressPercentage}%` }}
|
||
/>
|
||
</div>
|
||
|
||
{/* 進度文字 */}
|
||
<div className="mt-2 text-xs text-gray-500 text-center">
|
||
{progressPercentage.toFixed(1)}% 完成
|
||
</div>
|
||
</div>
|
||
)
|
||
}
|
||
```
|
||
|
||
### 8.3 載入狀態和錯誤處理
|
||
|
||
**LoadingStates 組件**：
|
||
```typescript
|
||
export const LoadingStates = ({
|
||
isLoadingCard,
|
||
isAutoSelecting,
|
||
showNoDueCards,
|
||
showComplete,
|
||
onRestart,
|
||
onBackToFlashcards
|
||
}) => {
|
||
// 無詞卡狀態
|
||
if (showNoDueCards) {
|
||
return (
|
||
<div className="text-center py-12">
|
||
<div className="bg-blue-50 border border-blue-200 rounded-lg p-8 max-w-md mx-auto">
|
||
<div className="text-blue-400 text-6xl mb-4">🎉</div>
|
||
<h3 className="text-xl font-semibold text-blue-700 mb-4">太棒了！</h3>
|
||
<p className="text-blue-600 mb-6">目前沒有需要複習的詞卡</p>
|
||
<div className="space-y-3">
|
||
<button
|
||
onClick={onRestart}
|
||
className="w-full px-6 py-3 bg-blue-600 text-white rounded-lg hover:bg-blue-700"
|
||
>
|
||
重新載入
|
||
</button>
|
||
<button
|
||
onClick={onBackToFlashcards}
|
||
className="w-full px-6 py-3 border border-blue-300 text-blue-700 rounded-lg hover:bg-blue-50"
|
||
>
|
||
回到詞卡管理
|
||
</button>
|
||
</div>
|
||
</div>
|
||
</div>
|
||
)
|
||
}
|
||
|
||
// 載入中狀態
|
||
if (isLoadingCard || isAutoSelecting) {
|
||
return (
|
||
<div className="text-center py-12">
|
||
<div className="animate-spin rounded-full h-12 w-12 border-b-2 border-blue-600 mx-auto mb-4" />
|
||
<p className="text-gray-600">
|
||
{isAutoSelecting ? '正在為您挑選適合的詞卡...' : '載入中...'}
|
||
</p>
|
||
</div>
|
||
)
|
||
}
|
||
}
|
||
```
|
||
|
||
## ⚡ 性能考量和優化
|
||
|
||
### 9.1 組件層級優化
|
||
|
||
**React.memo 記憶化**：
|
||
```typescript
|
||
// 高頻重新渲染的組件使用記憶化
|
||
export const FlipMemoryTest = memo(FlipMemoryTestComponent)
|
||
export const VocabChoiceTest = memo(VocabChoiceTestComponent)
|
||
export const ChoiceGrid = memo(ChoiceGridComponent)
|
||
|
||
// Props 比較函數
|
||
const arePropsEqual = (prevProps: ReviewProps, nextProps: ReviewProps) => {
|
||
return (
|
||
prevProps.cardData.id === nextProps.cardData.id &&
|
||
prevProps.disabled === nextProps.disabled
|
||
)
|
||
}
|
||
|
||
export const ExpensiveTestComponent = memo(TestComponent, arePropsEqual)
|
||
```
|
||
|
||
**useCallback 和 useMemo 優化**：
|
||
```typescript
|
||
// 避免不必要的函數重新創建
|
||
const handleAnswerSelect = useCallback((answer: string) => {
|
||
if (disabled || showResult) return
|
||
setSelectedAnswer(answer)
|
||
onAnswer(answer)
|
||
}, [disabled, showResult, onAnswer])
|
||
|
||
// 複雜計算的記憶化
|
||
const shuffledOptions = useMemo(() => {
|
||
return generateOptionsWithDistractors(cardData, allCards)
|
||
}, [cardData.id, allCards])
|
||
```
|
||
|
||
### 9.2 狀態管理性能
|
||
|
||
**Zustand 細粒度訂閱**：
|
||
```typescript
|
||
// 使用 subscribeWithSelector 進行精確訂閱
|
||
export const useTestQueueStore = create<TestQueueState>()(
|
||
subscribeWithSelector((set, get) => ({
|
||
// store implementation
|
||
}))
|
||
)
|
||
|
||
// 組件中選擇性訂閱，避免不必要重渲染
|
||
const currentTest = useTestQueueStore(state =>
|
||
state.testItems[state.currentTestIndex]
|
||
)
|
||
|
||
const isCompleted = useTestQueueStore(state =>
|
||
state.completedTests >= state.totalTests
|
||
)
|
||
```
|
||
|
||
**狀態批量更新**：
|
||
```typescript
|
||
// 避免多次 setState，使用批量更新
|
||
const batchUpdate = useCallback((updates: Partial<TestQueueState>) => {
|
||
set(state => ({
|
||
...state,
|
||
...updates,
|
||
// 同時更新相關的衍生狀態
|
||
progressPercentage: (updates.completedTests || state.completedTests) /
|
||
(updates.totalTests || state.totalTests) * 100
|
||
}))
|
||
}, [])
|
||
```
|
||
|
||
### 9.3 網路請求優化
|
||
|
||
**請求快取和去重**：
|
||
```typescript
|
||
class ApiCache {
|
||
private static cache = new Map<string, { data: any; timestamp: number }>()
|
||
private static pendingRequests = new Map<string, Promise<any>>()
|
||
|
||
static async getCachedOrFetch<T>(
|
||
key: string,
|
||
fetcher: () => Promise<T>,
|
||
ttl = 5 * 60 * 1000 // 5分鐘快取
|
||
): Promise<T> {
|
||
// 檢查快取
|
||
if (this.cache.has(key)) {
|
||
const cached = this.cache.get(key)!
|
||
if (Date.now() - cached.timestamp < ttl) {
|
||
return cached.data
|
||
}
|
||
}
|
||
|
||
// 檢查是否有進行中的請求
|
||
if (this.pendingRequests.has(key)) {
|
||
return this.pendingRequests.get(key)!
|
||
}
|
||
|
||
// 發起新請求
|
||
const request = fetcher()
|
||
this.pendingRequests.set(key, request)
|
||
|
||
try {
|
||
const data = await request
|
||
this.cache.set(key, { data, timestamp: Date.now() })
|
||
return data
|
||
} finally {
|
||
this.pendingRequests.delete(key)
|
||
}
|
||
}
|
||
}
|
||
```
|
||
|
||
