Gym Class Scheduler Bot 🤖💪

This project is a Telegram bot that helps you book your gym classes in advance. You simply send a message to the bot to schedule your class, and the bot takes care of booking it for you automatically 24 hours before it starts. All powered by AWS Lambda and EventBridge (cron jobs). 🏋️‍♂️

How It Works

1. Telegram Bot: You chat with the bot to schedule your gym classes.
2. AWS Lambda (Webhook Handler): This handles incoming messages from Telegram and sets up the schedule as EventBridge rules.
3. AWS EventBridge (Cron Jobs): EventBridge rules are created to trigger the booking exactly 24 hours before your class starts.
4. AWS Lambda (Booking Handler): Once the scheduled time hits, this Lambda function automatically books your class.

Getting Started 🚀

What You Need

• AWS account
• Telegram Bot Token (create one using BotFather)
• AWS CDK

Structure

Two Lambda functions:

• TelegramWebhookHandler: Handles incoming messages and sets up EventBridge rules.
• GymBookingHandler: Books the gym classes 24 hours before the scheduled time.

EventBridge (Cron Jobs): - EventBridge is what schedules the booking. The first Lambda (TelegramWebhookHandler) creates the cron job when you schedule a class, which then triggers the booking Lambda 24 hours before the class.
