python-neva
The core of the Neva framework — a Laravel-inspired toolkit for Python that
brings Laravel's philosophy, terminology, and conventions to the Python
ecosystem: service providers, facades, bind/make dependency injection (on
dishka), Hash/Crypt/Config/Log/Event
facades, a transaction-aware event system, and Result/Option error handling.
python-neva is the framework-agnostic core. Web- and protocol-specific
concerns live in separate integration packages (the plugins below) so the core
never depends on a particular HTTP or messaging framework.
Plugins & ecosystem
Neva is split into one repository per package. The core is published as
python-neva; each plugin is an
independent repo, independently versioned and published.
| Package | Repo / directory | Role | Status |
|---|---|---|---|
python-neva |
neva/ |
Core, framework-agnostic. DI, service providers, facades, Result/Option, events, security, observability, SQLAlchemy database layer. | published (PyPI) |
neva-fastapi |
neva-fastapi/ |
FastAPI integration — App extends FastAPI and wires dishka into routes. Pulled in via the python-neva[fastapi] extra. |
published (PyPI) |
neva-asgi |
neva-asgi/ |
ASGI middleware — correlation IDs and per-request profiling. Pure ASGI, so both the HTTP and messaging integrations can consume it. Pulled in via the python-neva[asgi] extra. |
published (PyPI) |
neva-faststream |
neva-faststream/ |
FastStream (messaging) integration. | scaffolded, early placeholder |
neva-auth |
neva-auth/ |
Authentication & identity toolkit — token-issuance engine, OAuth2 grants, guards, pluggable formats/backends. | core complete, OAuth-server slice in progress |
neva-example |
neva-example/ |
Reference application consuming python-neva[fastapi]. Not published; demonstration + integration test bed. |
unpublished |
When working across packages locally, each repo can be cloned as a sibling directory; integration packages depend on
python-nevafrom PyPI (or an editable local path during development).
Develop
uv sync # install/refresh deps from uv.lock
poe lint # ruff check
poe fmt # ruff format
poe tc # type-check (pyrefly)
poe test # pytest
poe test-cov # tests with coverage

asyncio_mode = "auto" is set, so async tests need no @pytest.mark.asyncio.
Contributing
Commits follow Conventional Commits
with gitmoji prefixes, enforced by
cz_gitmoji. Commitizen is
provided as a dev dependency — no separate install needed. Run the guided
wizard:
cz commit
or format manually as :gitmoji: type(scope): subject.
Releases are cut per-repo with commitizen, from the repo root:
cz bump # bump version in pyproject, write CHANGELOG, tag v<version>
git push --follow-tags origin main
uv build && uv publish # build + publish the wheel/sdist
cz bump derives the bump level (major/minor/patch) from the commits since the
last tag, updates CHANGELOG.md, and runs scripts/retag-with-changelog.sh to
rewrite the new tag with the rendered changelog as its annotation.
Feature ideas
- Feature-parity FastStream integration (now scaffolded as
neva-faststream) - Finish cleaning up the core package (moving any remaining ASGI-dependent code into the appropriate integration packages)
- Improved router registration (auto-discovery OR provider-based? both?)
- Improved security tooling (performance improvements, better defaults, etc.)
- Better OpenTelemetry integration
- Improved factory module (based on Polyfactory)
- Queue/Jobs system
- CLI integration
