ViewSender — UI Management

ViewSender is responsible for delivering the UI to the user and synchronizing messages. It creates an SPA (Single Page Application) feel within Telegram.

🏗 How it Works

The service manages two persistent bot messages: 1. Menu — The navigation block at the top. 2. Content — The main information block.

Instead of sending new messages for every click, ViewSender edits existing ones, storing their IDs in a database (coordinates).

🔒 Group Isolation

ViewSender automatically detects the chat type: * Private Chats: Coordinates are bound to the user_id. * Groups & Topics: Coordinates are bound to the chat_id or thread_id. This prevents interface conflicts when different users interact with the bot in the same group.

🔋 Storages

Two storage modes are supported for message IDs: 1. Redis (Production): Persists the interface even after bot restarts. Uses high-performance Redis Hashes. 2. In-Memory (Dev): Stores data in RAM. Ideal for development without a Redis instance.

🧹 Garbage Collection

Together with the GarbageStateRegistry, ViewSender can automatically delete old messages and keyboards during transitions between logical blocks, keeping the chat history clean.
