| 94 | + |
| 95 | +--- |
| 96 | + |
| 97 | +## 4. Route List Created |
| 98 | + |
| 99 | +| Route | Label | WPF Source View | |
| 100 | +|-------|-------|----------------| |
| 101 | +| `/` | Dashboard | DashboardView | |
| 102 | +| `/install` | Install | InstallView | |
| 103 | +| `/library` | Library | LibraryView | |
| 104 | +| `/browse` | Browse | BrowseView | |
| 105 | +| `/backups` | Backups | BackupsView | |
| 106 | +| `/config` | Config | ConfigView | |
| 107 | +| `/diagnostics` | Diagnostics | DiagnosticsView | |
| 108 | +| `/history` | History | HistoryView | |
| 109 | +| `/profiles` | Profiles | ProfilesView | |
| 110 | +| `/settings` | Settings | SettingsView | |
| 111 | +| `/logs` | Log Viewer | LogViewerView | |
| 112 | +| `/safe-mode` | Safe Mode | SafeModeView | |

| 114 | +| `/oiv` | OIV Creator | OivView | |
| 115 | +| `/cleanup` | Cleanup | CleanupView | |
| 116 | +| `/patrol-readiness` | Patrol Readiness | PatrolReadinessDashboardView | |
| 117 | +| `/setup` | Setup Wizard | SetupWizardView | |
| 118 | + |
| 119 | +--- |
| 120 | + |
| 121 | +## 5. Stub Screens Created |
| 122 | + |
| 123 | +All 17 stub pages render identically via `StubPage`: |
| 124 | +- Screen label (heading) |
| 125 | +- Route path (`/route`) |
| 126 | +- WPF source view name |
| 127 | +- "Not migrated yet" badge |
| 128 | + |
| 129 | +`/setup` is excluded from the sidebar nav (wizard flow, not a regular nav item). |
| 130 | + |
| 131 | +--- |
| 132 | + |
| 133 | +## 6. Scripts Added to package.json |
| 134 | + |
| 135 | +| Script | Command | |
| 136 | +|--------|---------| |
| 137 | +| `dev` | `vite` | |
| 138 | +| `build` | `tsc -b && vite build` | |
| 139 | +| `typecheck` | `tsc -b` | |
| 140 | +| `lint` | `eslint .` | |
| 141 | +| `preview` | `vite preview` | |
| 142 | + |
| 143 | +--- |
| 144 | + |
| 145 | +## 7. Commands Run and Results |
| 146 | + |
| 147 | +| Command | Result | |
| 148 | +|---------|--------| |
| 149 | +| `npm install` (in `frontend/`) | Pass — 214 packages, 0 vulnerabilities | |
| 150 | +| `npm run typecheck` | Pass — 0 TypeScript errors | |
| 151 | +| `npm run lint` | Pass — 0 lint errors | |
| 152 | +| `npm run build` | Pass — dist/ produced (315 kB JS, 6.6 kB CSS) | |
| 153 | +| `dotnet build LSPDFRManager.sln` | Pass — 0 errors, 11 pre-existing warnings | |
| 154 | +| `dotnet test` | Pass — 914/914 | |
| 155 | + |
| 156 | +--- |
| 157 | + |
| 158 | +## 8. Deviations from Migration Plan |
| 159 | + |
| 160 | +| Item | Plan | Actual | Reason | |
| 161 | +|------|------|--------|--------| |
| 162 | +| Tailwind setup | `tailwindcss` CSS plugin | `@tailwindcss/vite` Vite plugin | Tailwind v4 uses Vite plugin instead of PostCSS; compatible and simpler | |
| 163 | +| `ApiError` constructor | Parameter properties | Explicit field + assignment | TypeScript `erasableSyntaxOnly: true` disallows constructor parameter properties | |
| 164 | +| `/setup` in nav | Not specified | Excluded from sidebar | Setup wizard is a first-launch flow, not a regular navigation destination | |
| 165 | + |
| 166 | +--- |
| 167 | + |
| 168 | +## 9. Remaining Frontend Setup Work |
| 169 | + |
| 170 | +- [ ] Vite proxy config for LocalApi (needed in Milestone 4) |
| 171 | +- [ ] Per-feature API client modules in `lib/api/` (one per feature area, Milestones 5–13) |
| 172 | +- [ ] TypeScript DTO types in `src/types/` matching C# DTOs (Milestones 5+) |
| 173 | +- [ ] React DevTools / TanStack Query DevTools (optional, add in dev mode) |
| 174 | +- [ ] 404 / not-found route |
| 175 | +- [ ] Error boundary at app level |
| 176 | +- [ ] `frontend/.gitignore` already present from Vite scaffold (covers `dist/`, `node_modules/`) |
| 177 | + |
| 178 | +--- |
| 179 | + |
| 180 | +## 10. How This Prepares the App for the React UI Migration |
| 181 | + |
| 182 | +- **All 17 routes** are registered and navigable immediately; any stub can be replaced with a real screen without changing routing or layout. |
| 183 | +- **`routeConfig.ts`** provides a typed map from route path → WPF source → migration status; future milestones update `status` field from `'stub'` to `'in-progress'` or `'complete'`. |
| 184 | +- **`queryClient.ts`** is wired at the app root; any page can call `useQuery` or `useMutation` without additional setup. |
| 185 | +- **`lib/api/client.ts`** provides typed `get/post/put/delete` helpers; feature API modules plug in by calling these helpers with `/api/v1/...` paths once LocalApi is live. |
| 186 | +- **Tailwind v4** is configured via Vite plugin; no `tailwind.config.js` needed; CSS custom properties define the navy/blue color scheme matching the WPF dark theme. |
| 187 | +- **`dist/`** is ready to be embedded in `LSPDFRManager.LocalApi/wwwroot/` and served as static files in Milestone 4. |
