Poetry's dependency groups (1.2.0+) let you split runtime, test, lint, and optional dependencies into named sets and install only what each CI stage or environment needs — smaller images, faster pipelines.
Learn how to declare dependency groups in pyproject.toml, install only runtime deps for production, and verify a lean environment.
Poetry 1.2+ dependency groups keep dev tooling out of published wheels, while extras remain the only way to let downstream users select optional features via pip. Use both: groups for test/lint/docs, extras for public feature flags like [redis] or [async].
Poetry’s lock file records exact versions and hashes, uses a backtracking resolver to handle conflicts, and gates optional dependencies so reproducible builds are achievable across platforms—if you verify on each target OS.
Learn how to eliminate long-lived secrets in PyPI deployments using Trusted Publishing. This guide covers the OIDC architecture, trust boundaries, and configuration for token-less uploads.
Learn when to use Source Distributions (sdist) versus Wheels (.whl) for PyPI packages to balance installation speed and cross-platform compatibility.
Learn how to choose between Source Distributions (sdist) and Binary Wheels for PyPI. This guide compares installation speed, compatibility, and the manylinux standard to help you implement a hybrid publishing strategy.
Decide where each non-core dependency lives in a Poetry project: groups for internal tooling, extras for user-facing optional features, markers for platform conditions — with a concrete pyproject.toml layout, install commands per environment, and validation steps.
Since mid 2022 it is now possible to get rid of setup.py , setup.cfg in favor of pyproject.toml . Editable installs work with recent versions of setuptools and pip and even the official packaging tutorial switched away from setup.py to pyproject.toml . However, documentation regarding requirements.txt seems to be have been also removed, and I wonder where to
