+# ZephyrFS Web Interface
2
+
3
+A modern web interface and WebDAV server for ZephyrFS distributed storage system.
4
+
5
+## Features
6
+
7
+- **RESTful API** - Complete file management operations
8
+- **JWT Authentication** - Secure token-based authentication
9
+- **WebDAV Server** - Native OS integration for mounting as network drive
10
+- **Real-time Updates** - WebSocket-based status monitoring
11
+- **Zero-Knowledge Security** - Preserves ZephyrFS encryption architecture
12
+- **High Performance** - Sub-2-second response times with streaming support
13
+
14
+## Quick Start
15
+
16
+### Development
17
+
18
+1. **Install dependencies**
19
+   ```bash
20
+   cd server
21
+   npm install
22
+   ```
23
+
24
+2. **Configure environment**
25
+   ```bash
26
+   cp .env.example .env
27
+   # Edit .env with your settings
28
+   ```
29
+
30
+3. **Start development server**
31
+   ```bash
32
+   npm run dev
33
+   ```
34
+
35
+### Production
36
+
37
+1. **Build the application**
38
+   ```bash
39
+   npm run build
40
+   ```
41
+
42
+2. **Start production server**
43
+   ```bash
44
+   npm start
45
+   ```
46
+
47
+### Docker
48
+
49
+```bash
50
+docker-compose up -d
51
+```
52
+
53
+## API Endpoints
54
+
55
+### Authentication
56
+- `POST /api/auth/login` - Login with username/password
57
+- `POST /api/auth/refresh` - Refresh access token
58
+- `POST /api/auth/logout` - Logout and invalidate session
59
+- `GET /api/auth/me` - Get current user info
60
+
61
+### Files
62
+- `GET /api/files` - List files in directory
63
+- `POST /api/files/upload` - Upload file
64
+- `GET /api/files/:id/download` - Download file
65
+- `GET /api/files/:id/info` - Get file metadata
66
+- `DELETE /api/files/:id` - Delete file
67
+
68
+### Status
69
+- `GET /api/health` - Health check
70
+- `GET /api/status/network` - Network status
71
+- `GET /api/status/node` - Node status
72
+- `GET /api/status/ws` - WebSocket status updates
73
+
74
+### WebDAV
75
+- `GET /api/webdav` - WebDAV discovery info
76
+- `ALL /api/webdav/*` - WebDAV protocol endpoints
77
+
78
+## WebDAV Setup
79
+
80
+The WebDAV server allows mounting ZephyrFS as a network drive:
81
+
82
+### Windows
83
+1. Open File Explorer
84
+2. Right-click "This PC" → "Map network drive"
85
+3. Click "Connect to a Web site"
86
+4. Enter: `http://localhost:3000/api/webdav/`
87
+5. Username: `zephyrfs`, Password: `webdav`
88
+
89
+### macOS
90
+1. Open Finder
91
+2. Go → Connect to Server (⌘K)
92
+3. Enter: `http://localhost:3000/api/webdav/`
93
+4. Username: `zephyrfs`, Password: `webdav`
94
+
95
+### Linux
96
+1. Open file manager
97
+2. Other Locations → Connect to Server
98
+3. Enter: `http://localhost:3000/api/webdav/`
99
+4. Username: `zephyrfs`, Password: `webdav`
100
+
101
+## Configuration
102
+
103
+Environment variables (see `.env.example`):
104
+
105
+- `PORT` - Server port (default: 3000)
106
+- `ZEPHYRFS_NODE_URL` - ZephyrFS node URL
107
+- `JWT_SECRET` - JWT signing secret (min 32 chars)
108
+- `CORS_ORIGINS` - Allowed CORS origins
109
+- `WEBDAV_ENABLED` - Enable WebDAV server
110
+- `LOG_LEVEL` - Logging level (debug, info, warn, error)
111
+
112
+## Testing
113
+
114
+```bash
115
+npm test
116
+```
117
+
118
+## Architecture
119
+
120
+The web interface acts as a bridge between web clients and the ZephyrFS node:
121
+
122
+```
123
+Web Client/WebDAV → Fastify API → ZephyrFS Client → ZephyrFS Node
124
+```
125
+
126
+- **Fastify** - High-performance web framework
127
+- **JWT Authentication** - Stateless authentication
128
+- **WebDAV Server** - Standards-compliant DAV implementation
129
+- **ZephyrFS Client** - HTTP client for node communication
130
+- **Zero-Knowledge** - Encryption keys never leave client side
131
+
132
+## Security
133
+
134
+- JWT tokens with configurable expiration
135
+- Rate limiting (100 requests/minute per IP)
136
+- Security headers (HSTS, CSP, etc.)
137
+- CORS protection
138
+- Input validation with Zod schemas
139
+- Secure error handling (no info leakage)
140
+
141
+## Performance
142
+
143
+- Sub-200ms API response times
144
+- Streaming file uploads/downloads
145
+- Efficient chunked transfer
146
+- WebSocket real-time updates
147
+- Connection pooling and timeouts
