82-100: 行数計算ロジックの改善提案

現在の実装では固定の文字数(50文字)で行の折り返しを計算していますが、実際のテキストエリアの幅やフォントサイズに応じて動的に計算する方がより正確です。

以下の改善案を検討してください:

-  const calculateRows = (text: string): number => {
+  const calculateRows = (text: string): number => {
+    if (!textareaRef.current) return 1
+    
     const minRows = 1
     const maxRows = 5
     const lines = text.split('\n')
-
-    const baseRows = Math.max(minRows, lines.length)
-
-    // 長い行がある場合、追加の行を考慮(おおよその計算)
-    const extraRows = lines.reduce((acc, line) => {
-      const charsPerLine = 50 // 平均的な1行の文字数(概算)
-      const lineRows = Math.ceil(line.length / charsPerLine)
-      return acc + Math.max(0, lineRows - 1)
-    }, 0)
-
-    return Math.min(maxRows, baseRows + extraRows)
+    
+    // 実際のテキストエリアの幅を使用して計算
+    const textarea = textareaRef.current
+    const style = window.getComputedStyle(textarea)
+    const fontSize = parseFloat(style.fontSize)
+    const width = textarea.clientWidth - parseFloat(style.paddingLeft) - parseFloat(style.paddingRight)
+    const charWidth = fontSize * 0.6 // 概算的な文字幅
+    const charsPerLine = Math.floor(width / charWidth)
+    
+    let totalRows = 0
+    lines.forEach(line => {
+      totalRows += Math.max(1, Math.ceil(line.length / charsPerLine))
+    })
+    
+    return Math.min(maxRows, Math.max(minRows, totalRows))
   }

205-261: フレックスボックスレイアウトへの改善

グリッドレイアウトからフレックスボックスに変更されたことで、より柔軟で保守性の高いレイアウトが実現されています。各要素の配置とサイズ調整が適切に行われています。

アクセシビリティの観点から、以下の改善を検討してください:

 <textarea
   ref={textareaRef}
+  aria-label={t('EnterYourQuestion')}
   placeholder={
     chatProcessing
       ? `${t('AnswerGenerating')}${loadingDots}`
       : continuousMicListeningMode && isMicRecording
         ? t('ListeningContinuously')
         : t('EnterYourQuestion')
   }
   onChange={handleTextChange}
   onPaste={handlePaste}
   onKeyDown={handleKeyPress}
   disabled={chatProcessing || slidePlaying || realtimeAPIMode}
   className="bg-white hover:bg-white-hover focus:bg-white disabled:bg-gray-100 disabled:text-primary-disabled rounded-2xl w-full px-4 text-text-primary text-base font-bold disabled"
   value={userMessage}
   rows={rows}
   style={{
     lineHeight: '1.5',
     padding: '8px 16px',
     resize: 'none',
     whiteSpace: 'pre-wrap',
   }}
+  maxLength={2000}
 ></textarea>

PR Review for Auto-Resizing Message Input Feature

I've completed a comprehensive review of this PR focusing on code quality, potential issues, and best practices.

Review Checklist:

  • Analyze messageInput.tsx auto-resize implementation
  • Review workflow file changes
  • Check CLAUDE.md translation
  • Assess security and performance implications
  • Provide constructive feedback and suggestions

📋 Review Summary

This PR implements auto-resizing functionality for the message input textarea, translates documentation to Japanese, and includes minor workflow cleanup. Overall, the changes are functional but there are several opportunities for improvement.

🔍 Detailed Analysis

1. Code Quality & Best Practices

✅ Strengths:

  • Clean TypeScript implementation with proper type definitions
  • Good separation of concerns with props interface
  • Proper use of React hooks (useState, useEffect, useRef)
  • Consistent code formatting and structure
  • Appropriate use of Zustand stores for state management

⚠️ Areas for Improvement:

  • The auto-resize implementation is manual rather than truly automatic
  • Missing comprehensive input validation
  • No error handling for edge cases
  • Complex event handling logic could be simplified

2. Auto-Resize Implementation Analysis

Current Implementation:

// Lines 76-99: Manual row handling in handleKeyPress
const handleKeyPress = (event: React.KeyboardEvent<HTMLTextAreaElement>) => {
  // ... existing logic for Enter and Backspace
  if (event.key === 'Enter' && event.shiftKey) {
    setRows(rows + 1)  // Manual increment
  } else if (event.key === 'Backspace' && rows > 1 && userMessage.slice(-1) === '\n') {
    setRows(rows - 1)  // Manual decrement
  }
}

⚠️ Issues Identified:

  1. Not truly auto-resizing: Requires user keyboard input (Shift+Enter, Backspace)
  2. Inconsistent behavior: Doesn't handle paste operations or programmatic text changes
  3. No content-based calculation: Doesn't measure actual text content to determine optimal rows
  4. Limited to keyboard events: Won't work with mouse/touch interactions

💡 Recommended Improvements:

// Suggested implementation for true auto-resizing
const calculateRows = useCallback((text: string): number => {
  const minRows = 1;
  const maxRows = 5;
  const lines = text.split('\n');
  
  // Calculate rows based on content length and line breaks
  let totalRows = lines.length;
  
  // Account for text wrapping (simplified calculation)
  const approxCharsPerLine = 50; // Should be dynamic based on element width
  lines.forEach(line => {
    if (line.length > approxCharsPerLine) {
      totalRows += Math.ceil(line.length / approxCharsPerLine) - 1;
    }
  });
  
  return Math.min(maxRows, Math.max(minRows, totalRows));
}, []);

// Auto-resize on text change
useEffect(() => {
  setRows(calculateRows(userMessage));
}, [userMessage, calculateRows]);

3. Potential Bugs & Issues

🐛 Critical Issues:

  1. Focus management bug (lines 58-72): Clears textarea value on every render when not processing, which could cause data loss
  2. Keyboard event handling: Complex logic in handleKeyPress could miss edge cases
  3. Missing cleanup: No cleanup for refs or event listeners

🔧 Security Concerns:

  • No input sanitization or length limits on userMessage
  • No validation on textarea content
  • XSS prevention relies solely on React's built-in escaping

⚠️ Performance Considerations:

  • No debouncing on text changes
  • Re-renders on every character input
  • loadingDots animation could be optimized
  • Missing useCallback for event handlers

4. Accessibility & UX Issues

Missing Accessibility Features:

  • No aria-label or aria-describedby attributes
  • No character count indicator
  • No max length validation
  • Missing keyboard navigation enhancements

UX Improvements Needed:

  • Visual feedback for row changes
  • Better placeholder text management
  • Smoother transitions between states

5. Test Coverage

❌ Major Gap: No tests exist for the MessageInput component

  • Complex component with multiple states and interactions
  • 11 props with various event handlers
  • Multiple conditional rendering paths
  • Integration with multiple stores

📋 Recommended Test Cases:

// Essential test scenarios
describe('MessageInput', () => {
  it('should auto-resize based on content')
  it('should handle keyboard shortcuts correctly')
  it('should disable during processing states')
  it('should focus on non-touch devices')
  it('should handle paste operations')
  it('should validate input length')
  it('should clear on successful send')
})

6. Other File Reviews

✅ CLAUDE.md Translation:

  • Comprehensive Japanese translation
  • Maintains technical accuracy
  • Proper structure and formatting
  • Suggestion: Add note about environment variable management when adding new settings

✅ Workflow Files:

  • Clean formatting improvements
  • No functional changes
  • Good maintenance practice

🎯 Recommendations for Future PRs

  1. Implement True Auto-Resize: Replace manual keyboard handling with content-based calculation
  2. Add Comprehensive Tests: Critical for a component with this complexity
  3. Improve Accessibility: Add proper ARIA labels and keyboard navigation
  4. Add Input Validation: Implement length limits and sanitization
  5. Performance Optimization: Add debouncing and useCallback where appropriate
  6. Error Handling: Add graceful fallbacks for edge cases

🔐 Security Assessment

Low Risk: No critical security vulnerabilities identified, but consider:

  • Adding input length limits
  • Implementing content validation
  • Adding CSP headers for XSS protection

📊 Overall Assessment

✅ Functional: The feature works as intended
⚠️ Incomplete: Auto-resize is manual, not automatic
🔧 Maintainable: Code structure is good but could be improved
📈 Testable: Component structure supports testing but tests are missing

Recommendation: Accept the PR but consider follow-up improvements for true auto-resizing and comprehensive testing.
