Project Architecture

The repository is split by runtime responsibility:

backend/              Python application code
  bot/                Telegram bot, aiohttp APIs, webhooks, services
  config/             Pydantic settings and tariff/theme config loaders
  db/                 SQLAlchemy models, DAL, migrations
  main_backend.py     aiohttp backend entrypoint
  main_worker.py      background worker entrypoint
  main_migrate.py     one-shot migration entrypoint
  requirements.txt    Python runtime dependencies

frontend/             Svelte/Vite Mini App and admin UI
  src/                Svelte source code
  scripts/            frontend build helpers
  package.json        Node scripts and dependencies

deploy/
  docker/             Dockerfile, nginx and caddy runtime config
  compose/            legacy/alternate compose examples

data/                 runtime data mounted in containers
locales/              bot and Web App translations
tests/                Python test suite

The default docker-compose.yml stays in the repository root so docker compose up remains the simple production path. It builds three application images from deploy/docker/Dockerfile:

• backend: aiohttp APIs and webhooks only.
• worker: tariff traffic worker, panel sync, webhook queue consumers.
• frontend: static Svelte assets served by nginx.

The migrate service is a one-shot container based on the backend image. It is part of the default Compose dependency graph: Postgres and Redis become healthy, migrate applies Base.metadata.create_all and pending schema_migrations, then backend and worker start only after migrate exits successfully. This keeps migrations automatic for docker compose up without running them inside every backend replica.

Python imports intentionally remain bot.*, config.*, and db.*. Runtime containers set PYTHONPATH=/app/backend; local tests use the same layout through pytest.ini.

Common commands:

docker compose up -d --build
docker compose run --rm migrate
docker compose logs -f backend worker frontend
npm run build:webapp
pytest -q
