- "getDocumentContentUrl returns a plain string (no fetch) for use as iframe src or window.open target"
- "searchQuery watcher enforces 2-char minimum before API call — shorter inputs restore full list without hitting backend"

# Phase 4 Plan 08: Frontend Data Layer Summary
**One-liner:** Wired all Phase 4 backend endpoints to the frontend via 13 new API client functions, a new useFoldersStore (Pinia Composition API), extended useDocumentsStore with folder/search/sort/share state, and two new authenticated routes.
## Tasks Completed
| # | Task | Commit | Files |
|---|------|--------|-------|
| 1 | Add Phase 4 API functions to client.js and create folders store | 5417f26 | frontend/src/api/client.js, frontend/src/stores/folders.js |
| 2 | Extend documents store with folder/search/share actions + add Vue Router routes | 5417f26 | frontend/src/stores/documents.js, frontend/src/router/index.js |
## What Was Built
### API Client Extensions (frontend/src/api/client.js)
**`listDocuments` updated** to accept `folderId`, `q`, `sort`, `order` params — passed via `URLSearchParams` when non-null/non-empty.
**13 new functions added:**
| Group | Functions |
|-------|-----------|
| Folders | `listFolders`, `createFolder`, `getFolder`, `renameFolder`, `deleteFolder`, `moveDocument` |
| Shares | `createShare`, `listShares`, `deleteShare`, `getSharedWithMe` |
| Preferences | `getMyPreferences`, `updateMyPreferences` |
| Proxy URL | `getDocumentContentUrl` |
### Folders Store (frontend/src/stores/folders.js)
New Pinia Composition API store (`useFoldersStore`) following the exact `useTopicsStore` pattern:
- State: `folders`, `currentFolderId`, `breadcrumb`, `loading`, `error`
- Actions: `fetchFolders`, `createFolder`, `renameFolder`, `deleteFolder`, `navigateTo`
- `navigateTo` fetches folder detail for breadcrumb population; handles null (root) cleanly
### Documents Store Extensions (frontend/src/stores/documents.js)
- Added `watch` import from 'vue'
- New state refs: `currentFolderId`, `searchQuery`, `sortField`, `sortOrder`
- `fetchDocuments` extended to accept and pass `folderId`, `q`, `sort`, `order` to `api.listDocuments`
- Debounced `searchQuery` watcher: 300ms delay, 2-char minimum (T-04-08-03 mitigated)
- New share actions: `shareDocument`, `revokeShare`, `listShares`
- Return statement extended with all new state and actions
### Router Routes (frontend/src/router/index.js)
Two new lazy-loaded authenticated routes appended:
- `/folders/:folderId``FolderView.vue` (named `folder`)
- `/shared``SharedView.vue` (named `shared`)
Both use `meta: { requiresAuth: true }` and are guarded by the existing `beforeEach` hook.
## Deviations from Plan
None — plan executed exactly as written.
## Threat Mitigations Applied
| Threat | Mitigation |
|--------|-----------|
| T-04-08-01 — unguarded routes | Both new routes have `meta: { requiresAuth: true }` |
| T-04-08-03 — premature search | `searchQuery` watcher checks `newVal.length < 2` before firing API call |
## Known Stubs
None. This plan creates data layer only — no UI components with rendering stubs.
## Self-Check: PASSED
- `frontend/src/api/client.js` — FOUND, 45 export functions (13 new)
- `frontend/src/stores/folders.js` — FOUND, exports `useFoldersStore`
- `frontend/src/stores/documents.js` — FOUND, contains all new refs and actions
- `frontend/src/router/index.js` — FOUND, contains `/folders/:folderId` and `/shared` routes
- Commit `5417f26` — FOUND in git log
