Based on your goals, here’s a phased plan to gradually build up the functionality while ensuring that each step is solid before moving on. This way, we can ensure the basic connectivity is established first, and then add more complexity as we go.

Phased Approach

Phase 1: Establish the Basic Connection • Objective: Ensure your Worker can receive and respond to Telegram webhooks. • Tasks: • Set up a basic Hono app that listens for POST requests from Telegram. • Verify that your Worker is reachable at your cloudflare worker domain and that it correctly responds to test messages. • Confirm that your Telegram webhook is correctly configured (using your secret) and that messages are being received. • Outcome: A basic echo or “Hello, World!” bot that proves connectivity between Telegram and your Worker.

Phase 2: Integrate with the Teqtank API (Sandbox) • Objective: Establish connectivity with the Teqtank sandbox API. • Tasks: • Create a module (e.g., src/teqtank/api.ts) with functions to call key Teqtank endpoints. • Implement functions such as: • getAdminToken() – to obtain the global admin token. • authenticateRep(username, password) – to test rep authentication. • Log responses and errors to ensure that your API calls work as expected. • Outcome: Verified API connectivity with Teqtank. You should be able to retrieve tokens and simulate a rep authentication request.

Phase 3: Implement the Login Flow • Objective: Allow users to log in via your Telegram bot using their Teqtank credentials. • Tasks: • Create a command handler (e.g., in src/commands/auth.ts) to parse the /auth command. • Use the Teqtank API integration to authenticate the user with provided credentials. • Return a success or failure response back to Telegram. • Outcome: A working /auth command that calls the Teqtank API and notifies the user of the result.

Phase 4: Add KV-based Session Management • Objective: Manage user sessions securely with Cloudflare KV. • Tasks: • Create helper functions in a module like src/kv/session.ts to save, retrieve, and delete session data. • Upon successful login (from Phase 3), store the user session (e.g., Telegram chat ID and any user info from Teqtank) in KV with an appropriate TTL. • Implement middleware in your Hono app to check for an active session on subsequent commands. • Outcome: Users remain logged in across messages, and you have a centralized place to manage session state.

Phase 5: Implement the Logout Flow & Clean-Up • Objective: Allow users to log out securely and clear sensitive information. • Tasks: • Create a logout handler (e.g., in src/commands/logout.ts) that deletes the user’s session from KV. • Implement logic to remove or “disappear” sensitive messages (e.g., using the Telegram Bot API’s deleteMessage method) upon logout. • Outcome: A complete login/logout flow where sessions are managed in KV, and sensitive data is cleared when the user logs out.

Phase 6: Extend Functionality (Orders, Commissions, etc.) • Objective: Build additional features on top of the secure authentication and session management. • Tasks: • Develop endpoints/commands for handling orders, commission tracking, rank information, etc. • Reuse your established modules (authentication, KV, Teqtank API) to ensure consistency. • Optionally, add scheduled tasks (via src/schedule.ts) for token refresh or maintenance. • Outcome: A robust Telegram bot that not only manages authentication but also offers full business functionality.

Proposed Folder Structure

A well-organized project structure can help keep the code modular and maintainable. Here’s a proposed structure:

/ (project root) ├── package.json ├── wrangler.json // Your Cloudflare Worker configuration (secrets via wrangler, etc.) ├── tsconfig.json // TypeScript configuration ├── worker-configuration.d.ts // Auto-generated by Wrangler (for binding types) ├── README.md // Project documentation └── src ├── index.ts // Entry point: sets up the Hono app and routes ├── app.ts // (Optional) Hono app configuration and common middleware ├── commands // Handlers for Telegram commands │ ├── auth.ts // /auth command handler (login flow) │ ├── logout.ts // /logout command handler │ └── handleMessage.ts // Dispatcher for incoming messages (routing commands) ├── middleware // Middleware functions for the Hono app │ ├── telegramValidation.ts // Verify Telegram webhook secret and IP (if needed) │ └── rateLimiter.ts // Basic rate-limiting middleware ├── teqtank // Teqtank API integration │ └── api.ts // Functions to call Teqtank endpoints (getAdminToken, authenticateRep, etc.) ├── kv // KV helper functions │ └── session.ts // Functions to save, get, and delete session data └── schedule.ts // Scheduled tasks (CRON triggers for token refresh, cleanup, etc.)

Key Points in This Structure • Modularity: Each major feature (commands, middleware, API integration, session management) is isolated in its own directory. • Scalability: As you add more commands (e.g., order management, commission tracking), you can simply add new files under commands/ without cluttering the main app file. • Maintenance: With this separation, debugging and extending functionality (or even replacing one module with another) becomes much easier.

This phased approach and folder structure should help you build your project in manageable steps. Once you complete a phase, it’s a good point to commit your changes to GitHub so you can always roll back if needed.
