💡 Codex Review
https://github.com/andrerfneves/lightning-decoder/blob/f2117059216b1c86572f2a705761321c881f7c57/src/components/qr-scanner.tsx#L111-L113
When the QR dialog is opened, this component only renders static placeholder text and never mounts the @yudiel/react-qr-scanner Scanner or invokes the onScan/onError props. In the QR-code flow this means users can open the modal but no camera starts and scanned invoices are never decoded, whereas the previous implementation mounted Scanner and called the decode path.

UI Improvements: - iOS-style left/right layout in invoice details (key left, value right) - Color-coded badges for invoice types (BOLT11=blue, LNURL=purple, BOLT12=green, Lightning Address=orange) - Smart value truncation with tooltips for long strings (>50 chars) - Accordion components for arrays and nested objects - Amount formatting with BTC conversion tooltips - Relative timestamps with full date tooltips (e.g., '5m ago') - Separator lines between fields for better visual hierarchy URL Handling: - Added ?q= query parameter support (e.g., /?q=lnbc1...) - Maintained backwards compatibility with / path (e.g., /lnbc1...) - Query parameter takes precedence over path when both present Components Added: - Accordion (Radix UI) for collapsible sections - Tooltip (Radix UI) for hover information - Separator (Radix UI) for visual dividers All improvements maintain full backwards compatibility while providing a more polished, iOS-inspired user experience.
- Replaced placeholder text with actual @yudiel/react-qr-scanner Scanner component - Added handleScan callback that extracts rawValue and calls onScan prop - Added handleError callback that logs errors and calls onError prop - Scanner only mounts when dialog is open (open state) to avoid unnecessary camera access - Fixed QR scanner flow so users can actually scan and decode invoices Resolves Codex review feedback on PR #117

@chatgpt-codex-connector Fixed! ✅ The QR scanner was indeed a placeholder that rendered static text instead of the actual Scanner component. Here is what was changed: Root cause: Fix:
The QR scanner now works end-to-end: users can open the dialog, the camera starts, scan a QR code, and the decoded value flows to the app for decoding. Build passes successfully. Commit: |

Review Response
QR Scanner Fix (P1)
Status: ✅ Fixed in commit 0f5d09d
The QR scanner component was a placeholder that rendered static text instead of the actual Scanner from @yudiel/react-qr-scanner. The fix:
- Replaced placeholder div with actual
Scannercomponent - Implemented proper
handleScancallback that extractsresult[0].rawValueand callsonScan() - Implemented
handleErrorcallback for error handling - Scanner only mounts when dialog is open to avoid unnecessary camera access
- Added proper container styles for the aspect-ratio camera preview
The QR scanner now works end-to-end: open dialog → camera starts → scan QR → decoded value flows to the app for decoding.
Build: ✅ Passing
Tests: ✅ All 33 tests pass
- parseInvoice() was returning where handleLNURL() returns a fetch promise - This caused the invoice details card to render a Promise object instead of the actual LNURL metadata for bech32 LNURL inputs - Now properly awaits the handleLNURL promise before returning data - Lightning Address/BOLT11/BOLT12 were unaffected (already handled correctly) Resolves Codex review feedback about non-Lightning-Address LNURL rendering

@chatgpt-codex-connector Fixed! ✅
Root cause: parseInvoice() returned data: handleLNURL(requestCode) where handleLNURL() returns a fetch promise (.then(r => r.json())). The invoice details card was rendering the Promise object instead of the resolved LNURL metadata for bech32 LNURL inputs.
Fix: src/utils/invoices.js line 72
- Replaced
data: handleLNURL(requestCode)withconst lnurlData = await handleLNURL(requestCode) - Now properly awaits the promise before returning the resolved data
Lightning Address/BOLT11/BOLT12 were unaffected (already handled correctly via await).
Build: ✅ Passing
Tests: ✅ All 33 tests pass
Commit: 4484a17 - "fix: await LNURL fetch results before rendering"

New Feature: - Payment Hash Verifier page accessible via Tools > Payment Hash Verifier dropdown - Two-step verification flow: 1. Enter BOLT11/BOLT12 invoice → decode → extract payment hash 2. Enter preimage → compute SHA-256 → compare to payment hash - Visual match/no-match result with color-coded feedback (green/red) - Side-by-side comparison of invoice payment hash vs computed SHA-256 - Copy payment hash to clipboard functionality - Clear All button to reset the form - Back to Decoder button for easy navigation UI Changes: - Added Tools dropdown menu in header (Wrench icon) - Added Payment Hash Verifier option with Shield icon - Added view-based routing in App.tsx (home / payment-hash-verifier) - URL updates to /verify-payment-hash when on verifier page Technical: - Uses Web Crypto API for SHA-256 hashing - Extracts payment hash from both BOLT11 (payment_hash) and BOLT12 (paymentHash) - Handles hex strings and Buffer objects for payment hash extraction - Supports both BOLT11 tags array and top-level payment hash fields Resolves #92
- handleLNURL() now has proper error handling for fetch failures - Catches HTTP error responses (non-2xx status codes) and reports status code - Catches network errors (NetworkError, Failed to fetch) and reports CORS/offline - Catches JSON parse errors and reports invalid response - Shows meaningful error messages instead of generic 'Load error' - Defensive check for r.ok === false to avoid false positives in mocked environments Users now see helpful messages like: - 'Network error: Could not reach LNURL service. It may be offline or blocked by CORS.' - 'LNURL service returned 404 Not Found' - 'Invalid response: LNURL service returned non-JSON data.' Resolves #95
