## Features
- **Drag, click, or Ctrl+V paste** to upload; admins can use custom `folder` paths
- **Server-side WebP** (sharp), Referer hotlink protection, configurable public base URL
- **Multi-user** — username/password login; optional registration; users see only their images
- **Upload preferences** (card flip UI): client-side compression, auto-copy links, per-user auto-delete
- **Gallery** — browse, search, batch delete; admin sees uploader badges
- **Stats** — upload/delete metrics, folder breakdown; admin sees registered user count
- **API** — global token (admin) + per-user tokens; in-app cURL snippets
- **Twikoo** — `POST /api/index.php` (`image` + `token`)
- **Zero-config Docker** — first-run web wizard, no secrets required upfront
## Quick Start
### Docker (recommended)
```bash
git clone https://github.com/O96u/PicHost.git
cd PicHost
docker compose up -d
```
Default port: **6892**. Complete the setup wizard in the browser. Image: `muxui/pichost:latest` (fallback: `ghcr.io/o96u/pichost:latest`).
### Local development
```bash
npm install
cp .env.example .env # optional
npm run dev
```
Open `http://localhost:3000/setup` to create the admin account. Data defaults to `./data`.
### Legacy migration
If you only had `ADMIN_SECRET` and no user table, log in with the secret once and follow the migration wizard.
## Tech Stack
| Layer | Technology |
|-------|------------|
| Frontend | Nuxt 4, Vue 3, Nuxt UI 4, Tailwind CSS 4 |
| Backend | Nitro (Node.js), SQLite |
| Images | sharp (WebP transcoding & compression) |
| Auth | Session cookie, scrypt password hashing, API tokens |
| Storage | Local disk (`DATA_DIR`) |
| Deploy | Docker (amd64 / arm64), docker compose |
| Tests | Vitest |
## Environment variables
| Variable | Description |
|----------|-------------|
| `API_UPLOAD_TOKEN` | Global upload token (`Auth-Token` header); can be generated in the API page |
| `ALLOWED_REFERER_HOSTS` | Hotlink allowlist (comma-separated hostnames) |
| `IMAGE_BASE_URL` | Public base URL for image links |
| `WEBP_QUALITY` | Server WebP quality 1–100, default 80 |
| `AUTO_DELETE_DAYS` | Global auto-delete days (0 = off); admin + orphan images only |
| `DATA_DIR` | Data directory, default `/data` (container) or `./data` (local) |
| `ADMIN_SECRET` | Legacy v1.0 migration only |
| `DEV_BYPASS_ACCESS` | Dev only — bypass auth (never in production) |
Environment variables override database settings. See [`.env.example`](.env.example).
## Users & permissions
| Scenario | Auth | Ownership / visibility |
|----------|------|------------------------|
| Web upload | Session | Current user |
| API upload + **user token** | `Auth-Token` | Token owner |
| API upload + **global token** | `Auth-Token` | Admin (`userId` null) |
| Twikoo `/api/index.php` | form `token` | Same as global token |
| Gallery list / search / delete | Session or token | Users: own only; admin: all |
| Direct link `GET /images/...` | None (Referer rules) | Public if URL is known |
Regular users are limited to the `images/` folder; custom `folder` requires admin or global token.
## Storage layout
```
/data
├── pichost.db # SQLite: users, sessions, settings, logs
├── images/ # Default upload folder
├── blog/ # Example custom folder
└── twikoo/ # Twikoo comment images
```
Pattern: `folder/YYYY/MM/randomId.webp` + `.meta.json`. Back up the entire `/data` directory.
## API overview
| Method | Path | Description |
|--------|------|-------------|
| POST | `/api/images/upload` | Upload image |
| GET | `/api/images` | Paginated list |
| DELETE | `/api/images` | Delete one (`key`) |
| POST | `/api/index.php` | Twikoo / EasyImage 2.0 |
Upload example:
```bash
curl -X POST "https://pic.example.com/api/images/upload" \
-H "Auth-Token: YOUR_TOKEN" \
-F "folder=blog" \
-F "image=@./demo.png"
```
Full docs and copyable cURL snippets are on the **API** page after deployment.
## Twikoo
| Setting | Value |
|---------|-------|
| `IMAGE_CDN` | `easyimage` |
| `IMAGE_CDN_URL` | `https://your-domain/api/index.php` |
| `IMAGE_CDN_TOKEN` | Same as `API_UPLOAD_TOKEN` |
## Reverse proxy
- Proxy to port **6892**; HTTPS recommended
- Nginx: `client_max_body_size` ≥ 12m
- Set `IMAGE_BASE_URL` for public access
## Development
```bash
npm run dev # Dev server
npm run build # Production build
npm run start # Run .output
npm run lint # ESLint
npm run typecheck # Type check
npm test # Unit tests
```
## Roadmap
| Version | Plan |
|---------|------|
| **v1.0.0** | Local storage, multi-user, API, Twikoo (current) |
| **v1.1.0** | S3, Cloudflare R2, and more object storage backends |
