Frontend — Status

What it is

React 18 + TypeScript + Vite SPA. In dev it runs on port 5173 and proxies /api/* to backend:8000. In prod it is served by nginx on port 80.

All API calls go through src/api/client.ts (single Axios instance, JWT injected via request interceptor from localStorage).

Routes

Path	Component	Auth
/login	LoginPage	Public
/	DashboardPage	Required
/apps	AppsPage	Required
/apps/documents	DocumentsPage	Required
/apps/documents/settings/admin	DocumentAdminSettingsPage	Admin only
/apps/ai/settings/admin	AIAdminSettingsPage	Admin only
/admin	AdminPage	Admin only
/profile	ProfilePage	Required

PrivateRoute redirects to /login when no token. AdminRoute redirects to / when not admin.

Current functionality

Auth

• Login form (POST /api/auth/login) stores JWT in localStorage
• Logout clears token and redirects to /login
• GET /api/users/me verifies token on protected routes

Apps page (/apps)

Cards for each installed app:

• Documents — link to /apps/documents; admin gear icon → /apps/documents/settings/admin
• AI Service — infrastructure card; admin gear icon → /apps/ai/settings/admin; no Open button (no user-facing UI)

Documents page (/apps/documents)

Upload: PDF file input, 202 response, error display.

Filter bar:

• Search input (400ms debounce) — matches title, filename, tags, document_type
• Status dropdown (all / pending / processing / done / failed)
• Type dropdown (all / invoice / bill / receipt / order / expense / revenue / unknown)
• Sort selector (upload date / processed date / title / filename / file size / type / status)
• Asc/Desc toggle
• "Clear filters" button (appears when any filter is active)

Pagination: Prev/Next with "X–Y of Z" count. Only shown when total > per_page.

Document row (collapsed):

• Inline title editor (pencil icon, Enter to save, Esc to cancel; shows filename in italic when no title)
• Status badge (colour-coded)
• Document type label
• File size
• View button (opens PDF in new tab via blob URL — auth-gated)
• Download button
• Delete button (confirm dialog)

Document row (expanded):

• Tag editor — read mode shows chips + Edit button; edit mode has removable chips + input (Enter/comma to add) + Save/Cancel
• Extracted data table — all AI-extracted JSON fields (excludes tags, suggested_categories)
• Error message — shown if status=failed
• Categories — assigned chips with remove; dropdown to assign existing; AI-suggested chips with Accept / Create & Assign / Dismiss
• Status polling — auto-refetches every 3s while status is pending/processing; invalidates document list on done/failed

AI Admin Settings (/apps/ai/settings/admin)

• Provider selector (lmstudio / ollama / anthropic)
• Per-provider fields (base URL, model, API key)
• Test Connection button (POST /api/settings/ai/test)
• Save button

Document Admin Settings (/apps/documents/settings/admin)

• Upload Limits section only (max PDF size in MB)
• Save button

Admin page (/admin)

• User list with role and active status
• Inline role/status editing

Profile page (/profile)

• Display and edit personal information

API client (src/api/client.ts)

Key functions:

Function	Description
listDocuments(params)	GET /documents — returns DocumentPage
uploadDocument(file)	POST /documents/upload
deleteDocument(id)	DELETE /documents/{id}
downloadDocument(id, filename)	Blob URL download
viewDocument(id)	Blob URL → window.open, auto-revoke after 60s
getDocumentStatus(id)	Poll endpoint
listCategories()	All categories for user
createCategory(name)	Create category
assignCategory(docId, catId)	Assign
removeCategory(docId, catId)	Remove
updateDocumentTags(id, tags)	PATCH /documents/{id}/tags
updateDocumentTitle(id, title)	PATCH /documents/{id}/title
getAISettings()	GET /settings/ai (masked)
updateAISettings(data)	PATCH /settings/ai
testAIConnection()	POST /settings/ai/test
getDocumentLimits()	GET /settings/documents/limits
updateDocumentLimits(data)	PATCH /settings/documents/limits

---

State management

• TanStack Query — all server state; queryKey: ["documents", params] for cache isolation per filter/page combination
• No global store — local useState for UI-only state (editing mode, filter params, etc.)
• Token — localStorage, read by useAuth hook, injected by Axios interceptor

---

Known limitations / not implemented

• JWT in localStorage — XSS risk; migrate to httpOnly cookie when backend supports it
• No toast / notification system — errors shown inline; success is silent
• No loading skeletons — "Loading…" text only
• No UI component library — raw inline styles throughout; shadcn/ui + Tailwind CSS adoption in progress
• No group/sharing UI — blocked on backend groups system
• No app permission UI — all apps visible to all authenticated users

---

Future work

• UI component library: shadcn/ui + Tailwind CSS confirmed
• Toast notification system (upload success, save feedback, errors)
• Loading skeletons
• POST /queue/jobs integration — show AI processing queue status / progress per document
• Re-process document button (POST /documents/{id}/reprocess — needs backend endpoint first)
• Advanced filter: extracted data fields (vendor, due date, amount) — needs backend support
• Groups + document sharing UI — blocked on backend
• App permissions UI in Admin page
• httpOnly cookie auth (requires backend change)
• Bulk document operations (select multiple, bulk delete / bulk categorise)
