Dependency injection

modern-di — powerful DI framework with scopes.
modern-di-fastapi — modern-di integration for FastAPI.
modern-di-litestar — modern-di integration for LiteStar.
modern-di-faststream — modern-di integration for FastStream.
modern-di-typer — modern-di integration for Typer.
modern-di-pytest — modern-di integration for pytest.
that-depends — predecessor DI framework, still actively maintained.

Microservices, HTTP & messaging

lite-bootstrap — lightweight package for bootstrapping new microservices.
httpware — HTTP client framework with sync/async clients, middleware chain, and built-in resilience (retry, bulkhead).
faststream-redis-timers — FastStream broker integration for Redis-backed distributed timer scheduling.
faststream-concurrent-aiokafka — concurrent message processing middleware for FastStream with aiokafka.
faststream-outbox — FastStream broker integration for the transactional outbox pattern with Postgres.

Utilities

db-retry — retry helpers for database operations.
eof-fixer — automatically fix newlines at the end of files.
semvertag — auto-tag your GitHub/GitLab repo with semantic version tags from CI.
