🔄 API Conversion Complete

Overview

BotServer has been successfully converted from a Tauri-only desktop application to a full REST API server that supports multiple client types.

✅ What Was Converted to API

Drive Management (src/api/drive.rs)

Converted Tauri Commands → REST Endpoints:

Old Tauri Command New REST Endpoint Method
upload_file() /api/drive/upload POST
download_file() /api/drive/download GET
list_files() /api/drive/list GET
delete_file() /api/drive/delete DELETE
create_folder() /api/drive/folder POST
get_file_metadata() /api/drive/metadata GET

Benefits:

  • Works from any HTTP client (web, mobile, CLI)
  • No desktop app required for file operations
  • Server-side S3/MinIO integration
  • Standard multipart file uploads

Sync Management (src/api/sync.rs)

Converted Tauri Commands → REST Endpoints:

Old Tauri Command New REST Endpoint Method
save_config() /api/sync/config POST
start_sync() /api/sync/start POST
stop_sync() /api/sync/stop POST
get_status() /api/sync/status GET

Benefits:

  • Centralized sync management on server
  • Multiple clients can monitor sync status
  • Server-side rclone orchestration
  • Webhooks for sync events

Note: Desktop Tauri app still has local sync commands for system tray functionality with local rclone processes. These are separate from the server-managed sync.

Channel Management (src/api/channels.rs)

Converted to Webhook-Based Architecture:

All messaging channels now use webhooks instead of Tauri commands:

Channel Webhook Endpoint Implementation
Web /webhook/web WebSocket + HTTP
Voice /webhook/voice LiveKit integration
Microsoft Teams /webhook/teams Teams Bot Framework
Instagram /webhook/instagram Meta Graph API
WhatsApp /webhook/whatsapp WhatsApp Business API

Benefits:

  • Real-time message delivery
  • Platform-agnostic (no desktop required)
  • Scalable to multiple channels
  • Standard OAuth flows

❌ What CANNOT Be Converted to API

Screen Capture (Now Using WebAPI)

Status: ✅ FULLY CONVERTED TO WEB API

Implementation:

  • Uses WebRTC MediaStream API (navigator.mediaDevices.getDisplayMedia)
  • Browser handles screen sharing natively across all platforms
  • No backend or Tauri commands needed

Benefits:

  • Cross-platform: Works on web, desktop, and mobile
  • Privacy: Browser-controlled permissions
  • Performance: Direct GPU acceleration via browser
  • Simplified: No native OS API dependencies

Previous Tauri Implementation: Removed (was in src/ui/capture.rs)

formData.append('path', '/documents/');
formData.append('bot_id', '123');

await fetch('/api/drive/upload', {

  • Works on any device with HTTP client
  • Web, mobile, CLI, server-to-server

2. Scalability

  • Horizontal scaling with load balancers
  • Stateless API design
  • Containerized deployment

3. Security

  • Centralized authentication
  • OAuth 2.0 / OpenID Connect
  • Rate limiting and API keys

4. Developer Experience

  • OpenAPI/Swagger documentation
  • Standard REST conventions
  • Easy integration with any language

5. Maintenance

  • Single codebase for all platforms
  • No desktop app distribution
  • Rolling updates without client changes

🔮 Future Enhancements

API Versioning

/api/v1/drive/upload  (current)
/api/v2/drive/upload  (future)

GraphQL Support

query {
  files(path: "/documents/") {
    name
    size
    modified
  }
}

WebSocket Streams

const ws = new WebSocket('wss://api.example.com/stream');
ws.on('sync-progress', (data) => {
  console.log(`${data.percent}% complete`);
});

📝 Migration Checklist

  • Convert drive operations to REST API
  • Convert sync operations to REST API
  • Convert channels to webhook architecture
  • Migrate screen capture to WebAPI
  • Add OAuth 2.0 authentication
  • Document all API endpoints
  • Create client examples
  • Docker deployment configuration
  • Zero warnings compilation
  • OpenAPI/Swagger spec generation
  • API rate limiting
  • GraphQL endpoint (optional)

🤝 Contributing

The architecture now supports:

  • Web browsers (HTTP API)
  • Mobile apps (HTTP API)
  • Desktop apps (HTTP API + WebAPI for capture, Tauri for sync)
  • Server-to-server (HTTP API)
  • CLI tools (HTTP API)

All new features should be implemented as REST API endpoints first, with optional Tauri commands only for hardware-specific functionality that cannot be achieved through standard web APIs.
