From e920787d0be2dc5c5ef0f115f8e89fc85e997a64 Mon Sep 17 00:00:00 2001 From: 0xYYBB | ZYY | Bobo <128128010+the-dev-z@users.noreply.github.com> Date: Wed, 12 Nov 2025 17:56:36 +0800 Subject: [PATCH] fix(web): add auth guards to prevent unauthorized API calls (#934) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add `user && token` guard to all authenticated SWR calls to prevent requests with `Authorization: Bearer null` when users refresh the page before AuthContext finishes loading the token from localStorage. ## Problem When users refresh the page: 1. React components mount immediately 2. SWR hooks fire API requests 3. AuthContext is still loading token from localStorage 4. Requests sent with `Authorization: Bearer null` 5. Backend returns 401 errors This causes: - Unnecessary 401 errors in backend logs - Error messages in browser console - Poor user experience on page refresh ## Solution Add auth check to SWR key conditions using pattern: ```typescript user && token && condition ? key : null ``` When `user` or `token` is null, SWR key becomes `null`, preventing the request. Once AuthContext loads, SWR automatically revalidates and fetches data. ## Changes **TraderDashboard.tsx** (5 auth guards added): - status: `user && token && selectedTraderId ? 'status-...' : null` - account: `user && token && selectedTraderId ? 'account-...' : null` - positions: `user && token && selectedTraderId ? 'positions-...' : null` - decisions: `user && token && selectedTraderId ? 'decisions/...' : null` - stats: `user && token && selectedTraderId ? 'statistics-...' : null` **EquityChart.tsx** (2 auth guards added + useAuth import): - Import `useAuth` from '../contexts/AuthContext' - Add `const { user, token } = useAuth()` - history: `user && token && traderId ? 'equity-history-...' : null` - account: `user && token && traderId ? 'account-...' : null` **apiGuard.test.ts** (new file, 370 lines): - Comprehensive unit tests covering all auth guard scenarios - Tests for null user, null token, valid auth states - Tests for all 7 SWR calls (5 in TraderDashboard + 2 in EquityChart) ## Testing - ✅ TypeScript compilation passed - ✅ Vite build passed (2.81s) - ✅ All modifications are additive (no logic changes) - ✅ SWR auto-revalidation ensures data loads after auth completes ## Benefits 1. **No more 401 errors on refresh**: Auth guards prevent premature requests 2. **Cleaner logs**: Backend no longer receives invalid Bearer null requests 3. **Better UX**: No error flashes in console on page load 4. **Consistent pattern**: All authenticated endpoints use same guard logic ## Context This PR supersedes closed PR #881, which had conflicts due to PR #872 (frontend refactor with React Router). This implementation is based on the latest upstream/dev with the new architecture.
