Modern Python

Open-source templates and libraries for building production-ready Python applications — web services, microservices, and the dependency injection that wires them together.

Project templates

• fastapi-sqlalchemy-template — dockerized web application with DI on FastAPI, SQLAlchemy 2, PostgreSQL;
• litestar-sqlalchemy-template — dockerized web application on Litestar, SQLAlchemy 2, PostgreSQL.

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 PostgreSQL / SQLAlchemy 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.
