Dynamic Command Handlers
TBL supports dynamic command handlers for every Telegram update type. Any update (other than messages) can be handled automatically by creating a command following this pattern: /handle_{update_type}.
How It Works
When a specific update type occurs, TBL automatically runs the corresponding /handle_{type} command if it exists.
/*Command: /handle_chat_member*/
Bot.sendMessage("A chat member update occurred!")Supported Update Types
This feature works for all update types listed in the Telegram Bot API, including:
- my_chat_member
- chat_member
- chat_join_request
- business_message
- edited_business_message
- poll
- poll_answer
- message_reaction
- message_reaction_count
- chat_boost
- removed_chat_boost
Fallback Behavior
If a /handle_{update_type} command is not defined, the update will fall back to /channel_update (for channel-related updates) or * as a universal fallback.
/inline_query
Handles inline mode queries (when users type @yourbot query in Telegram).
/* Command: /inline_query */
Bot.sendMessage("You searched: " + request.query)/channel_update
Handles channel posts automatically.
/* Command: /channel_update */
Bot.sendMessage("New channel post received!")Example: Welcome Message on User Join
/* Command: /handle_chat_member */
if (request.new_chat_member && request.new_chat_member.user) {
Bot.sendMessage("👋 Welcome " + request.new_chat_member.user.first_name + " to the group!")
}Example: Poll Response Handler
/* Command: /handle_poll_answer */
Bot.sendMessage("User " + user.first_name + " answered a poll with option: " + request.option_ids)Best Practices
- Create handlers only for updates your bot needs
- Use the * command as a universal fallback for unhandled updates
- Keep handler commands focused on specific update types
- Test handlers thoroughly with different update scenarios
