+# Chat Service for realms.india
+
+A scalable, real-time chat service built with Drogon C++ framework and Redis for the realms.india streaming platform.
+
+## Features
+
+- **Real-time WebSocket Communication** - Instant message delivery
+- **Guest Chat Support** - Anonymous users with configurable naming patterns
+- **Redis-Based Storage** - Fast, in-memory message storage with configurable retention
+- **Moderation Tools** - Ban, mute, timeout, and message deletion
+- **Slow Mode** - Per-realm rate limiting
+- **Links Filtering** - Configurable link permission per realm
+- **Global/Local Channels** - Multi-channel support
+- **User Color Preservation** - Registered users maintain their platform colors
+- **Auto-cleanup** - Periodic message cleanup based on retention settings
+
+## Architecture
+
+### Components
+
+1. **Chat Service (Port 8081)** - Drogon-based C++ backend
+   - WebSocket server for real-time communication
+   - REST API for settings and moderation
+   - Redis integration for message storage
+
+2. **Redis Database 1** - Message and moderation data
+   - Messages (sorted sets per realm)
+   - Ban/mute lists
+   - Chat settings
+   - Slow mode tracking
+
+3. **PostgreSQL** - Persistent settings
+   - Realm chat configurations
+   - Chat moderators
+   - Global chat settings
+
+### Data Flow
+
+```
+Frontend (SvelteKit)
+    ↓ WebSocket
+OpenResty (Proxy)
+    ↓ /chat/*
+Chat Service (Drogon)
+    ↓
+Redis (Messages) + PostgreSQL (Settings)
+```
+
+## API Endpoints
+
+### WebSocket
+
+**Connect:** `ws://host/chat/stream/{realmId}?token=<jwt>`
+
+**Client → Server Messages:**
+```json
+{
+  "type": "message",
+  "content": "Hello world!",
+  "userColor": "#FF5733"
+}
+
+{
+  "type": "join",
+  "realmId": "realm-uuid"
+}
+
+{
+  "type": "mod_action",
+  "action": "ban|mute|timeout|delete",
+  "targetUserId": "user-uuid",
+  "messageId": "message-uuid",
+  "duration": 300,
+  "reason": "Spam"
+}
+```
+
+**Server → Client Messages:**
+```json
+{
+  "type": "welcome",
+  "username": "guest1234",
+  "userId": "guest:guest1234",
+  "isGuest": true,
+  "isModerator": false,

+  "type": "message_deleted",
+  "messageId": "uuid"
+}
+
+{
+  "type": "error",
+  "error": "You are muted"
+}
+```
+

+- `PUT /api/chat/settings/:realmId` - Update realm settings (moderator only)
+
+#### Moderation

+    "max_messages_per_realm": 1000,
+    "guest_prefix": "guest",
+    "guest_id_pattern": "{prefix}{number}",
+    "cleanup_interval_seconds": 300
+  }
+}
+```
+
+### Guest ID Patterns
+
+Customize guest usernames with placeholders:
+- `{prefix}` - Guest prefix (configurable)
+- `{number}` - Auto-incrementing number
+- `{random}` - Random 4-digit hex
+
+Examples:
+- `{prefix}{number}` → guest1, guest2, guest3...
+- `anon{random}` → anon4a7f, anonb2c9...
+- `friend_{number}` → friend_1, friend_2...
+
+## Realm Settings
+
+Customize chat behavior per realm (stored in PostgreSQL `realms` table):
+
+- `chat_retention_hours` (default: 24) - How long to keep messages
+- `chat_slow_mode_seconds` (default: 0) - Minimum seconds between messages
+- `chat_links_allowed` (default: true) - Allow URLs in messages
+- `chat_subscribers_only` (default: false) - Restrict chat to subscribers
+
+## Moderation
+
+### Moderators
+
+- Realm creators are auto-moderators
+- Admins are moderators everywhere
+- Additional moderators stored in `chat_moderators` table
+
+### Actions
+
+1. **Ban** - Permanent, prevents all messages
+2. **Mute** - Temporary silence (duration in seconds)
+3. **Timeout** - Short-term mute (typically 60s)
+4. **Delete Message** - Remove specific message
+
+## Redis Schema
+
+```
+# Messages (sorted set, score = timestamp)
+chat:messages:{realmId} → [{message JSON}, ...]
+
+# Global settings
+chat:settings:global → {guestPrefix, guestIdPattern, defaultRetentionHours}
+
+# Realm settings
+chat:settings:realm:{realmId} → {retentionHours, slowModeSeconds, ...}
+
+# Bans (set)
+chat:banned:{realmId} → {userId1, userId2, ...}
+
+# Mutes (string with TTL)
+chat:muted:{realmId}:{userId} → "1"
+
+# Slow mode tracking (string with TTL)
+chat:slowmode:{realmId}:{userId} → "1"
+
+# Active users (sorted set, score = last seen)
+chat:active:{realmId} → {userId: timestamp}
+
+# Guest counter
+chat:guest:counter → integer
+```
+
+## Building
+
+### Prerequisites
+- CMake 3.15+
+- C++20 compiler (GCC 10+ or Clang 12+)
+- Conan package manager
+- Docker (for containerized build)
+
+### Local Build
+
+```bash
+cd chat-service
+
+# Install dependencies
+conan install . --output-folder=build --build=missing -s compiler.cppstd=20
+
+# Build
+cd build
+cmake .. -DCMAKE_TOOLCHAIN_FILE=conan_toolchain.cmake -DCMAKE_BUILD_TYPE=Release
+cmake --build . -j$(nproc)
+
+# Run
+./bin/chat_service
+```
+
+### Docker Build
+
+```bash
+cd chat-service
+docker build -t chat-service .
+docker run -p 8081:8081 \
+  -e JWT_SECRET=your-secret \
+  -e REDIS_HOST=redis \
+  chat-service
+```
+
+## Deployment
+
+The chat service is automatically included in the main docker-compose.yml:
+
+```bash
+docker-compose up -d chat-service
+```
+
+## Frontend Integration
+
+### Basic Chat Panel
+
+```svelte
+<script>
+  import ChatPanel from '$lib/components/chat/ChatPanel.svelte';
+  export let realmId;
+  export let userColor = '#FFFFFF';
+</script>
+
+<ChatPanel {realmId} {userColor} />
+```
+
+### Pseudo-Terminal (~ key activation)
+
+```svelte
+<script>
+  import ChatTerminal from '$lib/components/chat/ChatTerminal.svelte';
+</script>
+
+<ChatTerminal defaultRealmId="realm-uuid" />
+```
+
+Add to your root layout to make it globally available.
+
+## Security
+
+- **JWT Authentication** - Required for registered users
+- **Rate Limiting** - 20 messages/second per IP at proxy level
+- **Content Validation** - Length limits, XSS prevention
+- **Moderator Checks** - Permission validation for all mod actions
+- **CORS** - Restricted to localhost origins in development
+
+## Performance
+
+- **WebSocket** - Persistent connections, minimal overhead
+- **Redis** - Sub-millisecond message retrieval
+- **Auto-cleanup** - Configurable retention to manage memory
+- **Message Cap** - Max 1000 messages per realm (configurable)
+
+## Monitoring
+
+Check service health:
+```bash
+curl http://localhost:8081/api/chat/admin/settings
+```
+
+View logs:
+```bash
+docker logs realms-chat-service
+```
+
+## Future Enhancements
+
+- [ ] Emoji support
+- [ ] Message reactions
+- [ ] Thread/reply support
+- [ ] User mentions (@username)
+- [ ] Rich media embeds
+- [ ] Chat commands (/me, /shrug, etc.)
+- [ ] Message search
+- [ ] Whispers/DMs
+- [ ] Channel creation (beyond realms)
+- [ ] Chatbot integration hooks

+# Forgejo Server Setup
+
+Git server with CI/CD for realms.india infrastructure.
+
+## Prerequisites
+
+- Droplet with Docker and Docker Compose installed (via Terraform cloud-init)
+- Volume mounted at `/mnt/forgejo`
+- DNS A record pointing to droplet IP
+
+## Initial Setup
+
+### 1. Copy configuration files
+
+```bash
+# SSH to Forgejo server via jump host
+ssh realms-forgejo
+
+# Copy files to /opt/forgejo
+cd /opt/forgejo
+# (upload docker-compose.yml, Caddyfile, .env.example)
+```
+
+### 2. Generate secrets and configure environment
+
+```bash
+cd /opt/forgejo
+cp .env.example .env
+
+# Generate secure values
+echo "FORGEJO_SECRET_KEY=$(openssl rand -hex 32)"
+echo "FORGEJO_INTERNAL_TOKEN=$(openssl rand -hex 32)"
+echo "FORGEJO_JWT_SECRET=$(openssl rand -hex 32)"
+echo "POSTGRES_PASSWORD=$(openssl rand -base64 24)"
+
+# Edit .env with generated values
+vim .env
+```
+
+### 3. Start Forgejo (without runner)
+
+```bash
+docker compose up -d forgejo-db forgejo caddy
+docker compose logs -f forgejo
+```
+
+### 4. Initial Forgejo Configuration
+
+1. Visit `https://bit.realms.pub`
+2. Create admin account (first user becomes admin)
+3. Configure settings as needed
+
+### 5. Register the Actions Runner
+
+```bash
+# Get runner token from Forgejo
+# Site Administration > Actions > Runners > Create new Runner
+
+# Register the runner
+docker compose run --rm forgejo-runner \
+  forgejo-runner register \
+  --instance https://bit.realms.pub \
+  --token YOUR_RUNNER_TOKEN \
+  --name realms-runner \
+  --labels ubuntu-latest,docker \
+  --no-interactive
+
+# Start the runner
+docker compose up -d forgejo-runner
+```
+
+### 6. Verify Setup
+
+```bash
+# Check all services
+docker compose ps
+
+# Check logs
+docker compose logs -f
+
+# Test Git SSH
+ssh -T git@bit.realms.pub -p 2222
+```
+
+## Maintenance
+
+### View logs
+```bash
+docker compose logs -f [service]
+```
+
+### Restart services
+```bash
+docker compose restart [service]
+```
+
+### Backup
+```bash
+# Stop services
+docker compose down
+
+# Backup volumes
+tar -czvf forgejo-backup-$(date +%Y%m%d).tar.gz /mnt/forgejo
+
+# Restart
+docker compose up -d
+```
+
+### Update Forgejo
+
+```bash
+# Pull new image
+docker compose pull forgejo
+
+# Recreate container
+docker compose up -d forgejo
+```
+
+## Troubleshooting
+
+### Runner won't start
+- Ensure runner is registered first
+- Check `/mnt/forgejo/runner-data/.runner` exists
+- Check logs: `docker compose logs forgejo-runner`
+
+### SSL certificate issues
+- Ensure DNS is properly configured
+- Check Caddy logs: `docker compose logs caddy`
+- Caddy auto-obtains certs, may take a minute on first start
+
+### Database connection issues
+- Check PostgreSQL is healthy: `docker compose ps`
+- Check logs: `docker compose logs forgejo-db`
+
+### Git SSH not working
+- Verify port 2222 is open in firewall
+- Test: `ssh -T git@bit.realms.pub -p 2222 -v`
