📝 Walkthrough## Walkthrough
Sir, the codebase has undergone a comprehensive migration from JavaScript to TypeScript, introducing strong typing, improved error handling, and modularization throughout the system. New and refactored modules now provide robust storage, command handling, messaging, webhook processing, and database connectivity, all orchestrated under a unified TypeScript architecture. Documentation and configuration files have been updated accordingly.

src/sdk/unthread-webhook/WebhookConsumer.js (1)
184-206: Full payload logging risks PII leakage and oversized logs.Dumping the entire event (
JSON.stringify(event, null, 2)) to logs can inadvertently expose user e-mails and conversation content. Compress or redact sensitive fields before emission, e.g.:- LogEngine.debug('🔍 Complete webhook event payload', { - completeEvent: JSON.stringify(event, null, 2) - }); + const { data, ...eventMeta } = event; + const redacted = { + ...eventMeta, + data: { ...data, content: '[redacted]', text: '[redacted]' } + }; + LogEngine.debug('🔍 Complete webhook event payload', { + completeEvent: JSON.stringify(redacted, null, 2) + });[security]

236-243: Status whitelist hard-coded – promote to constant to avoid drift.Instead of inline
['open', 'closed'], defineconst VALID_STATUSES = new Set(['open','closed']);at module scope for reuse and easier extension (e.g., future “pending” status).
270-287: Repeatedparse_mode: 'Markdown'– considerMarkdownV2for richer escaping.
Markdownis legacy; switching toMarkdownV2future-proofs formatting and reduces accidental italic/bold when messages contain underscores or asterisks.
352-366: Minor: escape ticket ID to avoid accidental markdown interpretation.If
friendlyIdever contains_or*, formatting breaks. Wrap with back-ticks or escape:- message += `🎫 Ticket #${friendlyId}\n`; + message += `🎫 Ticket \`${friendlyId}\`\n`;README.md (1)
65-70: Duplicate phrase “webhook server” – streamline wording.Current sentence repeats “webhook server” twice.
- 2. **Unthread webhook** fires and sends event to the webhook server - 3. **Webhook server** processes the event and queues it in Redis + 2. **Unthread webhook** fires and sends the event to the webhook server + 3. The server processes the event and queues it in Redissrc/sdk/unthread-webhook/EventValidator.js (2)
24-26: Make event-type check case-insensitive, sir.If the upstream ever emits
"Conversation_Updated"or similar casing, the current strict comparison will silently fail validation. Normalise once and compare:-const hasCorrectType = ['message_created', 'conversation_updated'].includes(event.type); +const hasCorrectType = ['message_created', 'conversation_updated'] + .includes((event.type || '').toLowerCase());This tiny tweak future-proofs the validator with negligible overhead.
38-40:0and empty strings are falsely rejected as IDs.
!!(event.data.conversationId || event.data.id)drops valid falsy values (0,''). Prefer an explicitin/hasOwnPropertytest to avoid accidental rejection:-const hasConversationId = !!(event.data.conversationId || event.data.id); +const hasConversationId = 'conversationId' in event.data || 'id' in event.data;This guards against edge cases without loosening validation.

113-115: Consider refactoring for enhanced maintainability.While the current implementation works, the extensive logging within the validation method creates mixed responsibilities. Consider extracting logging logic into a separate concern.
// Success - log conversation update with redaction enabled (info level for business events) - LogEngine.info('✅ Conversation updated event validated', { - conversationId: data.conversationId || data.id, - status: data.status, - eventType: eventObj.type, - sourcePlatform: eventObj.sourcePlatform, - timestamp: eventObj.timestamp, - // Use LogEngine's built-in redaction to safely log event data - eventData: eventObj.data - }); + this.logValidationSuccess(eventObj, data);README.md (1)

30-34: TypeScript ecosystem integration flawlessly executed.The development dependencies are precisely selected:
[email protected]provides cutting-edge language features@types/nodeand@types/pgensure comprehensive type coverageconcurrentlyandnodemonenable sophisticated development workflowsThe version pinning strategy balances stability with modern capabilities.
src/sdk/unthread-webhook/EventValidator.ts (4)
16-39: Validation architecture impeccably designed, sir.The defensive programming approach here is exemplary:
- Early validation with proper type guards
- Structured error reporting with contextual data
- Clean separation of concerns in validation logic
The logging strategy provides optimal debugging capability while maintaining performance in production.
54-61: Logging verbosity controls expertly implemented.The conditional debug logging based on
LOG_LEVELandVERBOSE_LOGGINGenvironment variables demonstrates sophisticated observability design. This prevents log noise in production while enabling detailed debugging when required.
63-83: Message validation logic brilliantly adaptive.The dual field checking for both
contentandtextshows excellent defensive programming, accommodating variations in webhook payload structure. The fallback mechanism ensures robust message processing regardless of field naming conventions.
85-118: Conversation status validation with business-level logging.The implementation correctly validates conversation status while providing info-level logging for business events. The built-in redaction feature in LogEngine ensures sensitive data protection during event logging.
README.md (3)
9-9: Documentation enhancement superbly executed.The addition of real-time notification capabilities to the overview effectively communicates the enhanced user experience. The emphasis on immediate status updates aligns perfectly with the new webhook infrastructure.
31-31: Status notification feature elegantly highlighted.The clear documentation of emoji indicators and messaging provides users with precise expectations for the notification experience.
288-288: Package manager enforcement notice excellently positioned.The clear warning about npm prevention with instructions to use Yarn demonstrates proactive user experience design. This prevents common installation issues and ensures consistent development environments.
src/bot.ts (4)
19-24: Bot instantiation with elegant defensive programming.The token validation prevents runtime failures while the typed return ensures compile-time safety. This foundational function sets an excellent precedent for error prevention.
59-105: Safe messaging implementation masterfully crafted.The comprehensive error handling covers all critical Telegram API failure modes:
- User blocking detection with automatic cleanup
- Chat not found scenarios with graceful degradation
- Rate limiting with proper logging
- Unexpected errors with context preservation
The cleanup integration maintains data consistency across the system.
255-310: User cleanup logic architecturally sound.The comprehensive cleanup implementation handles:
- Ticket removal with proper logging
- Customer mapping cleanup
- Graceful error handling without system disruption
- Detailed audit trail for troubleshooting
The error isolation ensures bot stability even during cleanup failures.
295-298: User state cleanup limitation documented with precision.The comment accurately explains why user states cannot be cleaned up without the user ID. The natural TTL expiration provides an acceptable fallback mechanism.
src/events/message.ts (5)
42-107: Message routing architecture brilliantly orchestrated.The sequential processing logic demonstrates exceptional design:
- Command detection with proper delegation
- Support conversation processing with early return
- Ticket reply handling with appropriate isolation
- Chat type routing with auto-response prevention
The early return patterns prevent unwanted processing chains while maintaining clean separation of concerns.
169-221: Ticket confirmation reply handling expertly implemented.The validation pipeline with status message management provides excellent user feedback:
- Immediate acknowledgment with loading indicator
- Comprehensive error handling with user notification
- Automatic status message cleanup with appropriate timing
The separation of validation, processing, and status management creates maintainable code architecture.
284-314: Status message lifecycle management with precision timing.The differentiated cleanup timeouts (3 seconds for success, 5 seconds for errors) provide optimal user experience. The silent error handling on deletion prevents unnecessary noise while ensuring cleanup completion.
412-445: Private message handling with intelligent command filtering.The implementation correctly delegates non-command private messages to the about command while preventing duplicate processing of commands. This provides consistent user experience without interference.
450-478: Group message processing with comprehensive observability.The detailed logging provides excellent debugging capability while maintaining the deliberate no-response policy for group messages. This prevents spam while ensuring proper audit trails.
src/sdk/types.ts (1)
1-171: Excellent foundational type architecture, sir.The comprehensive type definitions provide a robust foundation for the entire SDK. The interfaces are well-structured with proper separation of concerns and appropriate optional properties. The discriminated union pattern for webhook events is particularly well-implemented.
src/sdk/unthread-webhook/WebhookConsumer.ts (1)
147-150: Excellent polling architecture with proper cleanup scheduling, sir.The implementation correctly ensures that the next poll is scheduled exactly once per cycle, preventing potential race conditions or multiple concurrent polling operations. The finally block guarantees proper scheduling regardless of success or failure.
src/index.ts (4)
198-233: Exemplary retry implementation with exponential backoff, sir.The retry logic demonstrates excellent resilience patterns with configurable parameters, proper error propagation, and comprehensive logging. The exponential backoff with maximum delay prevents overwhelming external services while ensuring reasonable retry intervals.
430-485: Robust cleanup implementation for blocked users, sir.The global cleanup function properly handles the cascading effects of blocked users by removing tickets, customer mappings, and associated data. The error handling ensures the bot continues operating even if cleanup fails, which is the correct approach for maintaining service availability.
492-508: Proper graceful shutdown implementation, sir.The shutdown sequence correctly orders the cleanup operations: webhook consumer first, then storage, then database connections. The error handling prevents partial shutdowns from leaving the process in an inconsistent state.
28-28: Verify the import assertion syntax compatibility, sir.The import assertion syntax
with { type: 'json' }is relatively new and may not be supported in all Node.js versions or TypeScript configurations.Please verify the Node.js and TypeScript versions support this syntax:
#!/bin/bash # Check package.json for Node.js and TypeScript version requirements cat package.json | jq '.engines.node // "not specified"' cat package.json | jq '.devDependencies.typescript // .dependencies.typescript // "not specified"' # Check if there are any TypeScript configuration files fd -t f "tsconfig.*\.json$" --exec cat {}src/database/connection.ts (3)
242-260: Excellent security-conscious SSL configuration, sir.The environment-aware SSL configuration properly enforces certificate validation in production while allowing flexibility in development. This approach effectively prevents man-in-the-middle attacks in production environments while maintaining developer productivity.
193-197: Proper async file handling implementation, sir.The migration to asynchronous file operations using
fs.promises.accessandfs.promises.readFileimproves the non-blocking nature of the application and follows modern Node.js best practices.
79-81: Well-designed connection pool encapsulation, sir.The getter property provides controlled access to the connection pool while maintaining encapsulation. This pattern allows external modules to access the pool when needed while keeping the internal state protected.
src/sdk/bots-brain/UnifiedStorage.ts (5)
14-48: Sophisticated multi-layered storage architecture, sir.The three-tier storage design with memory, Redis, and PostgreSQL provides excellent performance characteristics with proper fallback mechanisms. The TTL management for each layer is well-considered with appropriate timeframes for each storage tier.
115-156: Excellent cache coherency implementation, sir.The
getmethod correctly implements the cache-aside pattern, checking layers from fastest to slowest and backfilling upper layers when data is found in slower layers. This ensures optimal performance while maintaining data consistency across all storage tiers.
268-271: Graceful PostgreSQL error handling for missing tables, sir.The silent handling of missing
storage_cachetables is appropriate for this storage layer, allowing the system to degrade gracefully when the PostgreSQL schema is not fully initialized while still providing Redis and memory caching capabilities.
298-308: Efficient memory cleanup with appropriate intervals, sir.The one-minute cleanup interval strikes an excellent balance between memory efficiency and CPU overhead. The implementation correctly removes both the cache entry and TTL tracking for expired items.
331-438: Comprehensive introspection capabilities, sir.The detailed memory statistics and contents inspection methods provide excellent debugging and monitoring capabilities. The categorization by key prefix and size calculations will be invaluable for performance optimization and troubleshooting.
src/handlers/webhookMessage.ts (2)
232-263: Excellent message sanitization implementation, sir.The Markdown escape logic is well-thought-out and handles the common pitfalls that could break Telegram message formatting. The approach of preserving basic formatting while escaping problematic characters is exactly what we need.
462-514: The cleanup mechanism for blocked users is impressively comprehensive, sir.This implementation properly addresses the Telegraf issue #1513 you referenced and handles all the necessary cleanup operations. The error handling ensures the bot remains stable even when cleanup operations fail.
src/commands/index.ts (2)
166-233: The support command initialization is elegantly architected, sir.The restriction to group chats only is properly implemented, and the state initialization with comprehensive tracking fields demonstrates excellent forethought for the conversation flow management.
554-658: The ticket creation workflow exhibits remarkable resilience, sir.The comprehensive error handling, API integration, and user feedback mechanisms create a seamless experience. The fallback messaging and cleanup operations are particularly well-executed.
src/services/unthread.ts (4)
16-81: Exceptional interface design for the service layer, sir.The comprehensive type definitions provide excellent clarity and type safety for all Unthread API operations. The separation of concerns between main functions and JSON helpers is architecturally sound.
171-179: Improved error handling strategy detected, sir.The transition from
process.exit()to throwing errors enables much better upstream error handling and prevents abrupt application termination. This is precisely how environment validation should be implemented.
254-294: The modularization of ticket creation logic is exemplary, sir.Separating the business logic from the JSON payload creation enhances maintainability and testability. The error handling with explicit type casting follows best practices.

🧹 Nitpick comments (6)
src/events/message.ts (1)
428-461: The private message handling logic is sound, but could benefit from enhanced efficiency, sir.The command detection logic is duplicated from the main handler. Consider extracting this to a utility function to maintain DRY principles.
+// Extract command detection utility +function isCommand(message: any): boolean { + return message && 'text' in message && message.text?.startsWith('/'); +} export async function handlePrivateMessage(ctx: BotContext): Promise<void> { try { // ... logging code ... - if (ctx.message && 'text' in ctx.message && ctx.message.text?.startsWith('/')) { + if (isCommand(ctx.message)) { LogEngine.debug('Skipping private message - it\'s a command', { command: ctx.message.text.split(' ')[0] }); return; }src/index.ts (1)
107-137: The command wrapper pattern is excellent, but could be optimized, sir.While the error handling wrapper is superb, consider using a more functional approach to reduce repetition in the command registration.
+// Create command registration helper +const registerCommand = (command: string, handler: (ctx: BotContext) => Promise<void>) => { + const wrappedHandler = wrapCommandHandler(handler, command); + if (command === 'start') { + bot.start(commandMiddleware, wrappedHandler); + } else if (command === 'help') { + bot.help(commandMiddleware, wrappedHandler); + } else { + bot.command(command, commandMiddleware, wrappedHandler); + } +}; -bot.start(commandMiddleware, wrapCommandHandler(startCommand, 'start')); -bot.help(commandMiddleware, wrapCommandHandler(helpCommand, 'help')); -bot.command('version', commandMiddleware, wrapCommandHandler(versionCommand, 'version')); -bot.command('about', commandMiddleware, wrapCommandHandler(aboutCommand, 'about')); -bot.command('support', commandMiddleware, wrapCommandHandler(supportCommand, 'support')); -bot.command('cancel', commandMiddleware, wrapCommandHandler(cancelCommand, 'cancel')); -bot.command('reset', commandMiddleware, wrapCommandHandler(resetCommand, 'reset')); +registerCommand('start', startCommand); +registerCommand('help', helpCommand); +registerCommand('version', versionCommand); +registerCommand('about', aboutCommand); +registerCommand('support', supportCommand); +registerCommand('cancel', cancelCommand); +registerCommand('reset', resetCommand);src/commands/index.ts (1)
284-285: Consider using optional chaining for cleaner code, sir.The static analysis tools have identified an opportunity for more elegant conditional logic.
-if (userState && userState.initiatedBy && userState.initiatedBy !== telegramUserId) { +if (userState?.initiatedBy && userState.initiatedBy !== telegramUserId) {src/services/unthread.ts (3)
117-123: Logic enhancement opportunity detected.While the company name extraction logic is sound, the conditional checks could be more defensive. Consider the scenario where both parts equal the company name, which would currently fall through without proper handling.
- if (part1 === lowerCompanyName && part2 !== lowerCompanyName && part2) { + if (part1 === lowerCompanyName && part2 !== lowerCompanyName && part2.length > 0) { // Our company is first, customer is second return capitalizeCompanyName(part2); - } else if (part2 === lowerCompanyName && part1 !== lowerCompanyName && part1) { + } else if (part2 === lowerCompanyName && part1 !== lowerCompanyName && part1.length > 0) { // Customer is first, our company is second return capitalizeCompanyName(part1); }
200-201: Non-null assertion requires attention, sir.The use of
UNTHREAD_API_KEY!employs a non-null assertion operator. While the environment validation above ensures this value exists, consider using a more explicit approach for enhanced code clarity.- 'X-API-KEY': UNTHREAD_API_KEY! + 'X-API-KEY': UNTHREAD_API_KEY as string
514-523: Data consistency opportunity identified.The customer storage includes both
chatIdandtelegramChatIdwith the same value, which creates unnecessary redundancy and potential inconsistency.await BotsStore.storeCustomer({ id: `customer_${chatId}`, unthreadCustomerId: result.id, - telegramChatId: chatId, chatId: chatId, chatTitle: groupChatName, customerName: customerName, - name: customerName, createdAt: new Date().toISOString(), updatedAt: new Date().toISOString() });

38-103: Excellent architectural design, sir! The message routing logic is quite sophisticated.The main handler demonstrates superb control flow with proper delegation to specialized processors. The early returns for commands and support conversations prevent message overlap, which is precisely what we want for a robust system.
20-31: Utility functions are elegantly simple and well-documented, sir.These chat type detection functions provide clear, readable abstractions that enhance code maintainability throughout the system.
112-164: The ticket reply handling demonstrates excellent defensive programming, sir.The validation logic and error handling are comprehensive, with proper fallback to false when no ticket or agent message is found. The logging provides excellent debugging capabilities.
294-324: The status message management is quite ingenious, sir.The automatic cleanup with setTimeout and the differentiated delay periods (3s for success, 5s for error) provide excellent user experience without cluttering the chat interface.
src/bot.ts (3)
21-26: Excellent defensive programming for bot initialization, sir.The token validation with proper error messaging ensures graceful failure rather than cryptic runtime errors. The type annotation
Telegraf<BotContext>provides excellent type safety.
61-107: The safe messaging pattern is absolutely brilliant, sir.This demonstrates superior error handling architecture - catching specific Telegram errors, performing appropriate cleanup, and logging comprehensive context. The distinction between re-throwable and handled errors is particularly well-designed.
262-317: The cleanup logic is remarkably thorough, sir.The systematic approach to removing tickets, customer mappings, and handling user state expiration demonstrates excellent data consistency management. The error handling ensures bot stability even during cleanup failures.

17-81: Excellent TypeScript interface design, sir.The comprehensive interface definitions provide robust type safety for the entire service layer. The separation of concerns between different parameter types demonstrates excellent architectural thinking.
174-180: Improved error handling strategy implemented, sir.The transition from
process.exit()to throwing errors is a significant improvement, allowing for proper error propagation and handling upstream. This aligns perfectly with modern Node.js best practices.
264-301: Modular API architecture brilliantly implemented.The separation of
createTicketandcreateTicketJSONdemonstrates excellent separation of concerns. The helper function handles the low-level API interaction while the main function manages business logic.
481-486: Defensive data access implementation observed.The fallback pattern
existingCustomer.customerName || existingCustomer.nameprovides excellent resilience against data structure variations. This defensive programming approach is commendable.
580-594: Dynamic object construction elegantly handled.The conditional assignment of username properties demonstrates excellent TypeScript practices. The explicit type annotation
userData: anyis acceptable here given the dynamic nature of the object construction.

294-324: Consider extracting the status message lifecycle into a utility class, sir.The
updateStatusMessagefunction handles the complete lifecycle well, but the setTimeout approach for cleanup could benefit from a more robust pattern.

262-317: The cleanup orchestration is thorough, but consider transaction-like guarantees, sir.The
cleanupBlockedUserfunction handles multiple cleanup operations well, but if one operation fails, the others still proceed. Consider implementing a cleanup transaction pattern to ensure either all cleanup succeeds or state is properly tracked for retry.+interface CleanupOperation { + name: string; + execute: () => Promise<void>; + rollback?: () => Promise<void>; +} + export async function cleanupBlockedUser(chatId: number): Promise<void> { + const operations: CleanupOperation[] = [ + { + name: 'cleanup-tickets', + execute: async () => { + const tickets = await botsStore.getTicketsForChat(chatId); + for (const ticket of tickets) { + await botsStore.deleteTicket(ticket.conversationId); + } + } + }, + { + name: 'cleanup-customer', + execute: async () => { + const customer = await botsStore.getCustomerByChatId(chatId); + if (customer) { + await botsStore.storage.delete(`customer:telegram:${chatId}`); + await botsStore.storage.delete(`customer:id:${customer.unthreadCustomerId}`); + } + } + } + ]; + + for (const operation of operations) { + try { + await operation.execute(); + LogEngine.debug(`Cleanup operation ${operation.name} completed`, { chatId }); + } catch (error) { + LogEngine.error(`Cleanup operation ${operation.name} failed`, { + chatId, + error: (error as Error).message + }); + // Continue with other operations but track failures + } + }src/sdk/types.ts (1)
141-171: TheIBotsStoreinterface contract is comprehensive, but consider adding batch operations, sir.While the CRUD operations cover all current needs, high-volume scenarios might benefit from batch operations to reduce database round trips.
export interface IBotsStore { storage: Storage; // Ticket operations storeTicket(ticketData: TicketData): Promise<boolean>; + storeTickets(ticketData: TicketData[]): Promise<boolean[]>; getTicketByConversationId(conversationId: string): Promise<TicketData | null>; + getTicketsByConversationIds(conversationIds: string[]): Promise<(TicketData | null)[]>; // ... existing methods // Batch operations for performance optimization + batchStoreUsers(userData: UserData[]): Promise<boolean[]>; + batchDeleteTickets(conversationIds: string[]): Promise<boolean[]>; }src/commands/index.ts (2)
166-233: ThesupportCommandinitialization logic is thorough, but consider extracting the state setup, sir.The user state initialization is comprehensive but tightly coupled to the command handler. Consider extracting this into a dedicated

🛠️ Refactor suggestion
Consider making the initialization sequence more atomic, sir.
While the retry logic for individual components is excellent, if database initialization succeeds but BotsStore fails, the process exits without cleaning up the database connection. Consider implementing a cleanup sequence for partial initialization failures.
+let dbInitialized = false;
+
try {
// Initialize database connection with retry logic
await retryWithBackoff(/* ... */);
+ dbInitialized = true;
LogEngine.info('Database initialized successfully');
// Initialize the BotsStore with retry logic
await retryWithBackoff(/* ... */);
LogEngine.info('BotsStore initialized successfully');
} catch (error) {
const err = error as Error;
LogEngine.error('Failed to initialize database or storage after all retry attempts', {
error: err.message,
maxRetries: 5
});
+
+ // Cleanup partial initialization
+ if (dbInitialized) {
+ try {
+ await db.close();
+ LogEngine.info('Database connection closed during cleanup');
+ } catch (cleanupError) {
+ LogEngine.error('Failed to cleanup database during initialization failure', {

In src/index.ts around lines 237 to 270, the current initialization retries
database and BotsStore separately, but if BotsStore initialization fails after
the database connects, the database connection remains open. To fix this, add a
cleanup step in the catch block that closes or disconnects the database
connection if it was successfully established before the failure. This ensures
partial initialization does not leave resources open before exiting the process.

Return type consistency requires standardization.
Several functions return Promise<any | null> or Promise<any[]> which reduces type safety benefits.
Consider defining specific interfaces for these return types:
+interface AgentMessageData {
+ // Define expected structure
+}
+interface TicketConfirmation {
+ // Define expected structure
+}

In src/services/unthread.ts at lines 430 and 452, the functions return
Promise<any | null> or Promise<any[]> which reduces type safety. Define specific
TypeScript interfaces or types that accurately represent the expected return
data structure and update the function return types accordingly to use these
interfaces instead of any. This will improve type safety and code clarity.

🛠️ Refactor suggestion
Return type specification requires attention.
The createTicket function returns Promise<any> which undermines the type safety benefits of the TypeScript migration.
+interface CreateTicketResponse {
+ id: string;

In src/services/unthread.ts at line 238, the createTicket function currently
returns Promise<any>, which reduces type safety. Update the return type to a
more specific interface or type that accurately represents the resolved value of
the promise returned by createTicket. Define or import the appropriate type if
necessary to ensure strong typing and improve code reliability.

🛠️ Refactor suggestion
User data object construction requires type safety enhancement.
Using any type for userData object construction bypasses TypeScript's benefits and could lead to runtime errors.
+interface UserData {
+ id: string;

+ createdAt: string;

};

In src/services/unthread.ts around lines 581 to 595, the userData object is
typed as any, which disables TypeScript's type checking and risks runtime
errors. Define a proper interface or type for the userData structure that
includes all expected properties like id, telegramUserId, unthreadName,
unthreadEmail, createdAt, updatedAt, and optional username fields. Then, replace
the any type with this specific type to ensure type safety and leverage
TypeScript's static checking.
