# <img src="web/static/favicon.svg" width="32" alt="Bookhoard logo"> Bookhoard

A modern self-hosted media library system built with Go, PostgreSQL, HTMX, and Tailwind CSS featuring **universal cross-device sync**, beautiful dark themes, and comprehensive media management.

## ✨ Why Bookhoard?

**🔄 Universal Sync**: Your reading position, bookmarks, highlights, and notes sync automatically between KOReader and the web - with native Kobo sync and mobile apps coming later.

**📱 Multi-Library**: Organize your ebooks, comics, and manga with per-library folders and smart collections.

**🎨 Beautiful UI**: 11 gorgeous dark themes with responsive design that works on any device.

**🔒 Secure**: JWT authentication, bcrypt password hashing, rate limiting, and no passwords on devices.

## 🚀 Quick Start

### Prerequisites

- **Podman** (recommended) or Docker
- **5 minutes** of your time

### Installation

```bash
# 1. Clone the repository
git clone https://git.linuxhg.com/Bookhoard/bookhoard.git
cd bookhoard

# 2. Set up environment
cp .env.example .env
# Generate secure passwords (no special characters):
#   JWT_SECRET: openssl rand -hex 32
#   DBPASS: openssl rand -hex 16
# Edit .env with your generated values

# 3. Pull images and start the server
docker compose pull
docker compose up -d
# Optionally pin a specific version: set IMAGE_TAG in .env (defaults to "latest")

# 4. Open your browser
open http://localhost:8765
```

The first user to register automatically becomes an admin.

- **Format Conversion**: On-the-fly EPUB→KEPUB conversion (for upcoming native Kobo support)

### Media Management

- **Calibre Integration**: Automatic metadata import from Calibre `metadata.opf` sidecar files
- **Smart Search**: Partial matching with fuzzy search fallback for typos
- **Advanced Filtering**: Filter by author, series, genre, language, year, cover images
- **Dynamic Sorting**: By title, author, date added, published date, page count, series
- **Rich Metadata**: Title, author, series, publisher, ISBN, language, edition, tags
- **5-Star Ratings**: Half-star precision (1-10 scale)
- **Notes & Highlights**: Color-coded annotations with linked notes
- **Usage Analytics**: Reading statistics, device usage, popular books

### Smart Collections

- **Auto-Assign Rules**: Automatically add books based on genre, author, series, tags, language, publisher, year
- **Device Shelf Mappings**: Map collections to device shelves (used by native Kobo sync, coming soon)
- **Test Before Creating**: Preview which books match your rules

### Library Organization

- **Multi-Library Support**: Ebooks, Comics, and Manga with type-specific file formats
- **Multiple Folders**: Add multiple scanning folders per library
- **Visibility Control**: Admins control which libraries each user can see
- **Background Scanning**: Auto-scan with per-user frequency settings

### Security

- **JWT Authentication**: Short-lived access tokens (1 hour) with refresh tokens (7 days)
- **Strong Passwords**: Complexity requirements enforced (8+ chars, uppercase, lowercase, number, special)
- **Account Lockout**: 5 failed attempts = 15-minute lockout
- **Rate Limiting**: 10 requests/minute on auth endpoints
- **Input Validation**: Comprehensive validation on all inputs
- **No Passwords on Devices**: Web-based device approval with QR codes

## 💾 Network Storage (NAS / NFS / SMB)

Libraries on network mounts are supported for everyday use — serving,
reading, progress, and annotation sync all work over the mount — with a
few behaviors worth knowing:

- **Outage hysteresis.** When the mount drops, files miss one scan
  (marked missing, hidden) then a second (archived, still recoverable).
  When the mount returns — by path or by identical content elsewhere —
  everything is restored automatically: annotations, progress, and
  covers included.
- **Retention purge.** Archived items older than `ARCHIVE_RETENTION_DAYS`
  (default **90**, `0` = never auto-purge) are deleted for good by
  library scans, annotations included. A NAS offline longer than the
  retention window loses those books' metadata on return.
- **Deleting while the storage is down is refused.** Deleting a book
  cascades its annotations, so deletes are rejected with a clear error
  while the item's library storage is unreachable. Archive the item
  instead, or retry when the mount is back.
- **Watch mode does not fire on network mounts** (inotify doesn't work
  over NFS/SMB). The periodic scan is the change detector.
- **Latency** — folder reachability checks are cached ~30s; large
  libraries on slow mounts will still feel slower than local disk.
