python-app-boilerplate-25-d 1.0.1

Simple Python Boilerplate

python-app-boilerplate

Python application boilerplate. This boilerplate may be used for scripts, CLIs, or GUI or non GUI services.

Requirements

• Git 2.47.0+
• Python 3.12.6+
• uv 0.6.3+
• Docker 27.4.0+ [optional]

Problems

• No synchronization between uv-dynamic-versioning project version and docker image built. Current approach uses fallback version

[tool.uv-dynamic-versioning]
fallback-version = "0.0.0" 

• No tool for enforcing creation of pre-release branches to have a */* format like feat/some-feature. Current approach is giving coding guidelines

How to use

Development

1. Clone the repository in the pwd of your project.

git clone [e-mail]:25-d/python-app-boilerplate .

2. Install the project

uv sync --dev

3. Install pre-commit hooks

pre-commit install --hook-type pre-commit --hook-type commit-msg

4. Run the project

uv run app

5. Change instances of python_app_boilerplate_25_d to your project name in the following files and folders:

• pyproject.toml: project name and app script.
• README.md: Project structure, deployment.
• src/python_app_boilerplate_25_d: Folder name.
• *.py: Top path comment.
• docs/reference/api.md: Reference to python_app_boilerplate.

6. Commits should follow the conventional commits guideline for semantic-release to auto generate tags and versions that follow semantic-versioning in the CI/CD pipeline. Commitizen can be used to generate conventional commits

uv run cz commit

Profiling

1. Clone the repository in the pwd of your project.

git clone [e-mail]:25-d/python-app-boilerplate .

2. Install the project

uv sync --dev

3. Check the profiling/profiler.py script and replace the function under the comment to profile.

# Place function to profile here

4. Run the profiling script from the root of the project.

uv run profiling/profiler.py

5. Check the reports on profiling/reports.

Documentation

1. Clone the repository in the pwd of your project.

git clone [e-mail]:25-d/python-app-boilerplate .

2. Install the project docs dependencies

uv sync --group docs

3. Build the documentation

uv run mkdocs build

4. Serve the documentation locally or use built documentation in the site/ folder to deploy it on a web server.

uv run mkdocs serve

Committing, Formatting, Linting, Type Checking, and Testing

Before committing changes, make sure to run the commit check, formatter, linter, type checker, and tests.

• Pre-commit hooks will run the commit check, formatter, linter, and type checker before committing changes. To run the pre-commit hooks manually, use the following command:

pre-commit run --all-files

• (Optional) Run the commit check for conventional commits to test validate commit

uv run cz check --message commit

• (Optional) Run the linter and formatter

uv run ruff format
uv run ruff check --fix

• (Optional) Run the type checker

uv run mypy .

• (Optional) Run the tests and coverage

uv run pytest --cov

Deployment

• Scripts may not need a deployment or packaging
• CLIs, GUIs/non-GUI services could be deployed from a docker image or built, packaged and published to PyPI or Github Release
• GUIs application may need an specific command in Windows. reference

[project.gui-scripts]
app-gui = "python_app_boilerplate_25_d.main:main_gui"

Automatic release

1. Clone the repository

git clone [e-mail]:25-d/python-app-boilerplate .

2. Set up the PyPI and TestPyPi tokens in Github secrets used by .github/workflows/release.yml as environmental variables

3. Push to the main for releases, and to a */* format like branch for pre-releases

4. Once commited, the .github/workflows/release.yml workflow runs. semantic-release generates a git tag based on the .releaserc.json, and it pushes to github release. Finally, the running workflow publishes to PyPI or TestPyPi with the updated dynamic version from semantic-release using uv build and uv publish

release type	prerelease	release
Release type	*/*	main
Versioning	v1.0.0-rc.1	v1.0.0
Git Tag	v1.0.0-rc.1	v1.0.0
Git Releases	pre-release	release
Index Publishing	testPyPi	pyPi

Manual TestPyPi/PyPi

1. Clone the repository

git clone [e-mail]:25-d/python-app-boilerplate .

2. Build the project

uv build

3. Publish to an index using the --token flag with a token generated from PyPi or TestPyPi. Use --index testpypi flag to publish to TestPyPi as specified in the pyproject.toml, by default it publishes to PyPi.

uv publish

Docker

1. Clone the repository

git clone [e-mail]:25-d/python-app-boilerplate .

2. Build the Docker image from the root of the project

docker build . --file docker/app.Dockerfile --tag python-app

3. Run the Docker container

docker run python-app

Docker Compose

1. Clone the repository

git clone [e-mail]:25-d/python-app-boilerplate .

2. Build the Docker image from the root of the project. Pass the --build flag to rebuild the image if there are changes in the Dockerfile or the application code.

docker-compose --file docker/docker-compose.yml up --detach
