#🚀 QUICK START: Test the Fixed Search

#30-Second Verification

1. Open app in browser
2. Press F12 (DevTools)
3. Click "Network" tab
4. Go to S3 Browser
5. Click "Recursive" button
6. Type "test" in search
7. Wait 300ms...
8. ✅ See "POST /api/storage/search" in Network tab?
   → YES = Fixed! ✨
   → NO = Check steps above

#What You'll See

#Network Tab Shows

POST /api/storage/search
Status: 200 OK
Request: {"config": {...}, "query": "test"}
Response: {"results": [{...file1...}, {...file2...}]}

#File List Shows

Results for "test":
✓ test-file.pdf (2.1 MB)
✓ test-document.txt (5 KB)
✓ testing-guide.md (15 KB)
(from entire bucket, not just current folder)

#Console Shows

"Search found 3 results for "test""

#What Changed

#Before (Broken)

• ❌ Search only worked locally
• ❌ No network calls
• ❌ Stale closure bug

#After (Fixed)

• ✅ API calls working
• ✅ Server-side search
• ✅ Proper debouncing (300ms)
• ✅ Fresh state values

#How It Works

You type → UI updates instantly (searchQuery state)
      ↓
300ms timer runs (debouncing)
      ↓
Timer expires → API call sent (debouncedSearchQuery)
      ↓
If scope = "all": fetch "/api/storage/search"
      ↓
Results from server appear in file list ✨

#The Fix in Code

Replaced this broken code:

const handleSearchChange = (query: string) => {
  setTimeout(() => {
    if (searchScope === "all") {  // ❌ STALE!
      performRecursiveSearch(query);
    }
  }, 300);
};

With these proper React hooks:

// Debounce effect
useEffect(() => {
  // 300ms timeout to debounce
  setDebouncedSearchQuery(searchQuery);
}, [searchQuery]);  // ← Runs on every keystroke

// Search effect
useEffect(() => {
  // API call with FRESH searchScope
  if (searchScope === "all") {  // ✅ FRESH!
    fetch("/api/storage/search", {query: debouncedSearchQuery});
  }
}, [debouncedSearchQuery, searchScope, config]);  // ← Fresh values!

#Files Modified

Only 1 file changed:

• apps/flash-tools/src/app/s3-browser/page.tsx

Changes:

• Line 26: Added useEffect import
• Line 148: Added debouncedSearchQuery state
• Lines 151-210: Added 2 useEffect hooks
• Line 1072: Changed input handler

#Why This Works

React's useEffect dependency array ensures you get fresh values of state variables. No more stale closures!

// This guarantees fresh searchScope value:
}, [debouncedSearchQuery, searchScope, config]);
    ↑ searchScope is in array ↑

#Testing Checklist

• Open DevTools (F12)
• Go to Network tab
• Click "Recursive" button
• Type "test"
• Wait 300ms
• See POST /api/storage/search request
• See results in file list
• Console shows result count

✅ All checks pass? → FIXED! 🎉

#Common Questions

Q: Why 300ms debounce? A: Standard for search inputs. Prevents API overload while staying responsive.

Q: Can I change debounce delay? A: Yes! Line 163: }, 300); → Change 300 to your desired milliseconds.
