Bot starter template based on grammY bot framework and prisma ORM.
Uses PostgreSQL for data storage (MySQL, MongoDB, SQL Server, SQLite are also supported by prisma) and Redis for session storage.

• Config loading and validation
• Logger
• Sessions
• Language picker and internationalization
• Graceful shutdown
• Metrics collection (in prometheus format)
• Fast and low overhead fastify server
• Ready-to-use Docker setup

1. Clone this repo or generate new repo using this template via link

   git clone https://github.com/bot-base/telegram-bot-template

2. Create development and production environment variables files

   # development
   cp ./docker/bot.env.example ./docker/bot.dev.env
   cp ./docker/postgres.env.example ./docker/postgres.dev.env
   
   # production
   cp ./docker/bot.env.example ./docker/bot.prod.env
   cp ./docker/postgres.env.example ./docker/postgres.prod.env

3. Edit environment variables in docker/bot.dev.env and docker/bot.prod.env

   BOT_TOKEN — bot token, required to change. Get it from @BotFather.
   BOT_WEBHOOK — bot webhook url, required to change in production. Used for setup a webhook in production mode.
   BOT_ADMIN_USER_ID — administrator user ID. Administrator commands, such as /stats or /setcommands, will only be available to the user with this ID.

   NODE_ENV — environment (default is development, set production to use webhook)
   LOG_LEVEL — log level
   DATABASE_URL — database url
   REDIS_URL — redis url

4. Launch bot

   Development mode:

   # install dependencies
   npm i
   
   # run migrations
   docker-compose run bot npx prisma migrate deploy
   
   # run bot
   docker-compose up

   Production mode:

   # run migrations
   docker-compose -f docker-compose.yml -f docker-compose.prod.yml run bot npx prisma migrate deploy
   
   # run bot
   docker-compose -f docker-compose.yml -f docker-compose.prod.yml up
