What's inside

• TypeScript as a main language
• Telegraf as a bot framework of choice, because it's the most popular TypeScript bot framework
• Supabase as SaaS backend, because it's fast and free, and it's Postgres underneath
• Quickchart as a SaaS Chart.js provider, because it renders to the picture and is free

Usage
