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.
