like Discord, Slack, and Nextcloud using dependency injection and configuration-based selection. + +## Architecture Overview + +The chatbot provider system uses a flexible architecture with: + +- **Base Provider Interface**: Common contract for all chatbot providers (`ChatbotProvider.js`) +- **Provider Implementations**: Platform-specific implementations (Discord, Slack, Nextcloud) +- **Provider Factory**: Dependency injection container for managing providers (`ProviderFactory.js`) +- **Generic Controller**: Unified webhook handling logic (`chatbotController.js`) +- **Route Integration**: Clean API endpoints for each provider + +## Available Providers + +### Discord Provider +**Status**: βœ… Implemented +**Endpoint**: `POST /api/webhooks/chatbot/discord` + +Features: +- Ed25519 signature verification +- Slash command support +- Interactive component handling +- Message splitting for 2000 character limit +- Follow-up message support + +### Slack Provider +**Status**: 🚧 Placeholder (ready for implementation) +**Endpoint**: `POST /api/webhooks/chatbot/slack` + +Planned features: +- HMAC-SHA256 signature verification +- Slash command support +- Interactive component handling +- Thread support + +### Nextcloud Provider +**Status**: 🚧 Placeholder (ready for implementation) +**Endpoint**: `POST /api/webhooks/chatbot/nextcloud` + +Planned features: +- Basic authentication +- Talk app integration +- File sharing capabilities + +## Configuration + +### Environment Variables + +#### Discord +```bash +DISCORD_BOT_TOKEN=your_discord_bot_token +DISCORD_PUBLIC_KEY=your_discord_public_key +DISCORD_APPLICATION_ID=your_discord_application_id +DISCORD_AUTHORIZED_USERS=user1,user2,admin +DISCORD_BOT_MENTION=claude +``` + +#### Slack (Future) +```bash +SLACK_BOT_TOKEN=xoxb-your_slack_bot_token +SLACK_SIGNING_SECRET=your_slack_signing_secret +SLACK_AUTHORIZED_USERS=user1,user2,admin +SLACK_BOT_MENTION=@claude +``` + +#### Nextcloud (Future) +```bash +NEXTCLOUD_SERVER_URL=https://your-nextcloud.example.com +NEXTCLOUD_USERNAME=claude_bot +NEXTCLOUD_PASSWORD=your_nextcloud_password +NEXTCLOUD_AUTHORIZED_USERS=user1,user2,admin +NEXTCLOUD_BOT_MENTION=@claude +``` + +## API Endpoints + +### Webhook Endpoints + +- `POST /api/webhooks/chatbot/discord` - Discord webhook handler +- `POST /api/webhooks/chatbot/slack` - Slack webhook handler +- `POST /api/webhooks/chatbot/nextcloud` - Nextcloud webhook handler + +### Management Endpoints + +- `GET /api/webhooks/chatbot/stats` - Provider statistics and status + +## Usage Examples + +### Discord Setup + +1. **Create Discord Application** + - Go to https://discord.com/developers/applications + - Create a new application + - Copy Application ID, Bot Token, and Public Key + +2. **Configure Webhook** + - Set webhook URL to `https://your-domain.com/api/webhooks/chatbot/discord` + - Configure slash commands in Discord Developer Portal + +3. **Environment Setup** + ```bash + DISCORD_BOT_TOKEN=your_bot_token + DISCORD_PUBLIC_KEY=your_public_key + DISCORD_APPLICATION_ID=your_app_id + DISCORD_AUTHORIZED_USERS=user1,user2 + ``` + +4. **Test the Bot** + - Use slash commands: `/claude help me with this code` + - Bot responds directly in Discord channel + +### Adding a New Provider + +To add a new chatbot provider: + +1. **Create Provider Class** + ```javascript + // src/providers/NewProvider.js + const ChatbotProvider = require('./ChatbotProvider'); + + class NewProvider extends ChatbotProvider { + async initialize() { + // Provider-specific initialization + } + + verifyWebhookSignature(req) { + // Platform-specific signature verification + } + + parseWebhookPayload(payload) { + // Parse platform-specific payload + } + + // Implement all required methods... + } + + module.exports = NewProvider; + ``` + +2. **Register Provider** + ```javascript + // src/providers/ProviderFactory.js + const NewProvider = require('./NewProvider'); + + // In constructor: + this.registerProvider('newprovider', NewProvider); + ``` + +3. **Add Route Handler** + ```javascript + // src/controllers/chatbotController.js + async function handleNewProviderWebhook(req, res) { + return await handleChatbotWebhook(req, res, 'newprovider'); + } + ``` + +4. **Add Environment Config** + ```javascript + // In ProviderFactory.js getEnvironmentConfig(): + case 'newprovider': + config.apiKey = process.env.NEWPROVIDER_API_KEY; + config.secret = process.env.NEWPROVIDER_SECRET; + // Add other config... + break; + ``` + +## Security Features + +### Webhook Verification +Each provider implements platform-specific signature verification: +- **Discord**: Ed25519 signature verification +- **Slack**: HMAC-SHA256 signature verification +- **GitHub**: HMAC-SHA256 signature verification (existing) + +### User Authorization +- Configurable authorized user lists per provider +- Provider-specific user ID validation +- Graceful handling of unauthorized access attempts + +### Container Security +- Isolated execution environment for Claude commands +- Resource limits and capability restrictions +- Secure credential management + +## Provider Factory + +The `ProviderFactory` manages provider instances using dependency injection: + +```javascript +const providerFactory = require('./providers/ProviderFactory'); + +// Create provider from environment +const discord = await providerFactory.createFromEnvironment('discord'); + +// Get existing provider +const provider = providerFactory.getProvider('discord'); + +// Get statistics +const stats = providerFactory.getStats(); +``` + +## Error Handling + +The system provides comprehensive error handling: + +- **Provider Initialization Errors**: Graceful fallback and logging +- **Webhook Verification Failures**: Clear error responses +- **Command Processing Errors**: User-friendly error messages with reference IDs +- **Network/API Errors**: Automatic retry logic where appropriate + +## Monitoring and Debugging + +### Logging +All providers use structured logging with: +- Provider name identification +- Request/response tracking +- Error correlation IDs +- Performance metrics + +### Statistics Endpoint +The `/api/webhooks/chatbot/stats` endpoint provides: +- Provider registration status +- Initialization health +- Basic configuration info (non-sensitive) + +### Health Checks +Providers can be health-checked individually or collectively to ensure proper operation. + +## Future Enhancements + +- **Message Threading**: Support for threaded conversations +- **Rich Media**: File attachments and embeds +- **Interactive Components**: Buttons, dropdowns, forms +- **Multi-provider Commands**: Cross-platform functionality +- **Provider Plugins**: Dynamic provider loading +- **Advanced Authorization**: Role-based access control \ No newline at end of file diff --git a/package.json b/package.json index 57fd5cb..a7469fe 100644 --- a/package.json +++ b/package.json @@ -8,6 +8,7 @@
