A Project Template of Python with uv

Install

Please first install the latest uv. https://docs.astral.sh/uv/getting-started/installation/

Then run the following command to install runtime libraries.

uv sync --no-dev

Develop

uv sync

This installs the following tools in addition to runtime libraries.

• ruff
• ty
• pytest-cov
• pytest-xdist
• taskipy

The settings of those linter and formatters are written in pyproject.toml

VSCode Settings

Install/activate all extensions listed in .vscode/extensions.json

Creating Console Script

[project.scripts]
app = "app.cli:main"

Define Project Command

[tool.taskipy.tasks]
lint = "ruff check --fix ."
check = "ty check --fix ."
format = "ruff format ."
test = "pytest tests -n auto --cov=app --cov-report=term --cov-report=xml"

Build Docker Image

Please check the Dockerfile for how to use multi-stage build with uv. It also support AWS Lambda with AWS Lambda Web Adapter as well as multi-platform image with cross build approach. Dockerfile.lambda_native is used to build a image that uses AWS Lambda native protocol.

Build AWS Lambda Zip Package

Use one of the following scripts.

bash awslambda/build_package.sh --python-version 3.13 --python-arch aarch64
nu awslambda/build_package.sh --python-version 3.13 --python-arch aarch64
pwsh awslambda/build_package.ps1 -PythonVersion 3.13 -PythonArch aarch64

It requires your managed runtime is correctly configured to support AWS Lambda Web Adapter.

See https://github.com/awslabs/aws-lambda-web-adapter?tab=readme-ov-file#lambda-functions-packaged-as-zip-package-for-aws-managed-runtimes

The scripts internally use lzpb to make sure run.sh and bootstrap have exec permission. You can get the latest lzpb binary here. https://github.com/lucidfrontier45/lzpb/releases
