+## Project Overview
+
+MediaLore is a **self-hosted media library browser** for images and videos. It provides a web UI for browsing, searching, tagging, and viewing media with thumbnail previews and doom-scroll/TikTok-style consumption.
+
+**Monorepo** with two independent apps:
+- `backend/` — Python FastAPI server
+- `frontend/` — React SPA (TypeScript, Vite)

+## Environment Variables
+
+| Variable         | Default                             | Purpose                      |
+|------------------|-------------------------------------|------------------------------|
+| `DATABASE_URL`   | `sqlite+aiosqlite:////data/medialore.db` | SQLite connection string     |
+| `MEDIA_ROOT`     | `/media`                            | Root path for media libraries |
+| `THUMBNAIL_DIR`  | `/data/thumbnails`                  | Cached thumbnail storage     |
+
+Pydantic Settings reads from `.env` at startup (via `model_config = {"env_file": ".env"}`). For Docker, these are set in `docker-compose.yml`.
+
+## Database
+
+SQLite with **WAL mode** and a 10-second busy timeout (see `app/database.py:14-18`). Tables are auto-created at startup via `Base.metadata.create_all` in the FastAPI lifespan.
+
+### Schema
+
+- **libraries**: `id`, `name`, `path` (unique)
+- **media_items**: `id`, `library_id` (FK), `rel_path`, `filename`, `file_hash` (SHA-256), `media_type` ("image" or "video"), `size_bytes`, `missing`, `created_at`, `updated_at` — unique on `(library_id, rel_path)`
+- **tags**: `id`, `name`, `category` — unique on `(name, category)`
+- **media_item_tags**: `media_item_id` (FK), `tag_id` (FK), composite PK
+
+**Migrations**: Use Alembic. The initial migration is at `backend/alembic/versions/0001_initial_schema.py`.
+
+## API Conventions
+
+All endpoints are prefixed with `/api`. All responses are JSON except `/api/media/:id/file` (binary stream) and `/api/media/:id/thumbnail` (JPEG).
+
+### Async Database Access
+
+Routers use FastAPI's `Depends` injection with the `get_db` async generator from `database.py`:
+
+```python
+from app.database import get_db
+
+@router.get("/...")
+async def endpoint(db: AsyncSession = Depends(get_db)):
+    ...
+```
+
+### Frontend API Client
+
+All API calls go through the typed `api` object in `frontend/src/api/client.ts`. Use `useQuery` / `useMutation` from TanStack Query. Never call `fetch` directly from components.
+
+```ts
+import { api } from "../api/client";
+import { useQuery } from "@tanstack/react-query";
+
+const { data } = useQuery({
+  queryKey: ["libraries", id, "browse", path],
+  queryFn: () => api.libraries.browse(id, path),
+});
+```
+
+## Code Patterns & Conventions
+
+### Backend (Python)
+- **No linter configured** — follow the existing style (4-space indent, snake_case)
+- Models use SQLAlchemy 2.0-style `mapped_column` (not `Column()`)
+- Schemas use Pydantic `BaseModel`
+- Service modules handle business logic; routers handle HTTP concerns
+- Background scanning runs via `asyncio.create_task`; watchers run in separate threads via `watchdog.Observer`
+- Logging: use `logging.getLogger(__name__)` — the `app` namespace has a StreamHandler configured in `main.py`
+
+### Frontend (TypeScript/React)
+- **ESLint flat config** with strict TypeScript-ESLint rules
+- Inline `style={{ ... }}` objects for CSS (no CSS modules, no Tailwind)
+- TypeScript interfaces for all API types live in `client.ts`
+- Components use `useState`/`useEffect`/`useQuery` hooks, not class components
+- Theme state persisted in `localStorage` key `"theme"`, applied as `data-theme` attribute
+- Responsive via `window.matchMedia("(max-width: 767px)")` listener
+- File/thumbnail URLs constructed with `api.media.fileUrl(id)` and `api.media.thumbnailUrl(id)` (not fetched)
+
+### TypeScript Configuration
+- `tsconfig.app.json`: strict mode, `noUnusedLocals`, `noUnusedParameters`, `erasableSyntaxOnly`
+- `tsconfig.node.json`: for `vite.config.ts` only
+- Build command: `tsc -b && vite build` (type-check via project references)
+
+## Testing
+
+**There are no test files in this project.** No test framework is configured. When adding tests:
+- Frontend: consider Vitest (pairs with Vite) + React Testing Library
+- Backend: consider pytest + pytest-asyncio + httpx (for FastAPI TestClient)
+- No existing test commands in CI, so add them and consider a GitHub Action or similar
+
+## Docker / Deployment
+
+- `docker compose up -d` starts both services
+- Backend runs on port 8000 (internal), frontend Nginx on port 80 (mapped to 8085 on host)
+- Nginx proxies `/api/` to `http://backend:8000`
+- Media paths from the host are volume-mounted into the container at `/media`
+- Persistent data (DB, thumbnails) stored in Docker volume `medialore-data`
+
+## Important Notes
+
+- **No auth/authentication** — CORS allows all origins, no login system
+- Thumbnails are generated on first request and cached to disk (`THUMBNAIL_DIR`)
+- The scanner computes SHA-256 hashes to detect moved/renamed files and avoid re-processing
+- File watcher uses watchdog with per-library `PollingObserver` (necessary for Docker volumes)
+- `media_items.missing` flag is set when a scanned file no longer exists on disk
+- The frontend `build` command runs `tsc -b` first, which checks types across project references — type errors will block the build

+# MediaLore
+
+A self-hosted media library browser for images and videos. Organize your local media collections with tagged browsing, a file-system explorer, and a full-screen "doom scroll" viewer — all via a clean, responsive web UI.
+
+## Features
+
+- **Media Libraries** — Add local directories as named libraries; files are indexed by relative path within each library
+- **File Browser** — Navigate your library's directory structure with a thumbnail grid, breadcrumbs, and lazy-loaded previews
+- **Tagging System** — Organize media with named tags grouped into categories; create tags inline while viewing items
+- **Search** — Filter by filename (fuzzy match), tag, and/or library
+- **Doom Scroll** — Full-screen, swipe/scroll-driven media viewer for an immersive, social-media-like experience
+- **Live File Watching** — Automatically detects new, moved, and deleted files via `watchdog` (no manual rescans needed)
+- **Auto-Generated Thumbnails** — JPEG thumbnails for images (via Pillow) and videos (via ffmpeg)
+- **Dark / Light Theme** — Toggle with persistence via `localStorage`
+- **Responsive** — Mobile-friendly with a collapsible sidebar and touch gestures

+
+**Backend** — Python 3.12+, FastAPI, SQLAlchemy (async), aiosqlite, Alembic for migrations, `watchdog` for file-system events, Pillow for image thumbnails, ffmpeg for video thumbnails.
+
+**Frontend** — React 19, TypeScript, Vite 8, React Router 7, TanStack Query, Nginx (static serving + API proxy).
+
+## Quick Start (Docker Compose)
+
+### Prerequisites
+
+- Docker & Docker Compose
+- ffmpeg (bundled in the backend container)
+- Your media files accessible on the host (e.g. mounted from a NAS)
+
+### 1. Clone & configure
+
+```bash
+git clone <repo-url>
+cd MediaLore-Web-App
+cp .env.example .env
+```
+
+Edit `.env` to point `MEDIA_ROOT` to your host media directory:
+
+```env
+MEDIA_ROOT=/mnt/nas
+```
+
+> **Note:** Inside the container, `$MEDIA_ROOT` maps to `/media`. Library paths you add in the UI must be subdirectories of this mount.
+
+### 2. Start the stack
+
+```bash
+docker compose up --build -d
+```
+
+The frontend is available at `http://localhost:8085`.
+
+### 3. Add a library
+
+1. Open **Settings** → **Libraries**
+2. Enter a name and a path (e.g. `/media/Images/Photos`)
+3. Click **Add Library** — scanning begins in the background
+
+The scanner walks the directory tree, computes SHA-256 hashes, detects moved files by hash, and starts a file watcher for live updates.
+
+## Docker Compose Configuration
+
+```yaml
+services:
+  backend:
+    build: ./backend
+    volumes:
+      - medialore-data:/data          # DB + thumbnails
+      - /data/smb/adult/Images:/media/Images
+      - /data/smb/adult/Video Clips:/media/Video Clips
+    environment:
+      - DATABASE_URL=sqlite+aiosqlite:////data/medialore.db
+      - THUMBNAIL_DIR=/data/thumbnails
+
+  frontend:
+    build: ./frontend
+    ports:
+      - "8085:80"
+```
+
+Adjust the volume mounts to match your media layout. The `medialore-data` named volume persists the SQLite database and generated thumbnails across restarts.
+
