Telebot is a comprehensive Go framework for building Telegram bots that provides a clean abstraction over the Telegram Bot API. It features a robust middleware system, flexible context handling for update processing, and innovative patterns like the Sendable interface that enables transparent file handling. The framework supports both long polling and webhook approaches for receiving updates, and includes comprehensive support for Telegram features including payments, inline queries, callbacks, and business accounts. The architecture emphasizes separation of concerns with distinct components for bot core functionality, message types, media handling, and update routing. Notable design patterns include the Context interface that encapsulates update data and action capabilities, the Sendable interface that allows types to define their own sending behavior, and a dual API pattern for options that combines convenience flags with comprehensive options structs.
The LLM identified 3 files worth highlighting for reuse:
Defines the Sendable interface that allows types to implement their own sending behavior. This enables transparent file handling where media types know how to send themselves, eliminating boilerplate code for media transmission. The pattern is demonstrated through implementations for Photo, Audio, Video, and other media types that handle file uploads, thumbnail processing, and self-updating after sending.
Provides a Context interface that wraps Telegram updates and provides convenient access to sender, chat, message data, and action methods (Send, Reply, Edit, etc.). This abstraction decouples handler logic from raw update parsing while offering convenient access to relevant data and bot methods. The nativeContext implementation includes thread-safe storage for middleware data sharing.
Implements a dual API pattern for message options that accepts both functional flags (like tele.NoPreview, tele.Silent) and a comprehensive SendOptions struct. This provides convenience for simple cases while maintaining full API coverage for complex scenarios. The extractOptions method cleanly converts variadic options into a structured format.
