About This Project

Project Overview

AWS Lambda Artifact Builder is a Python library that solves the deployment challenges every Python team faces when building Lambda applications. After years of working with Lambda in production environments, I recognized that teams repeatedly solve the same problems independently: platform compatibility issues, dependency management complexity, and enterprise deployment workflows.

This project provides battle-tested solutions through a Command Pattern architecture that handles both Lambda Layer creation and deployment package building across pip, Poetry, and UV dependency managers.

Why This Project Exists

The Core Problem: Modern Python tools (Poetry, UV, pip) don’t naturally align with Lambda’s deployment requirements. Teams spend weeks building custom solutions for:

  • Platform compatibility (Windows/macOS → Linux)

  • Dependency separation (layers vs application code)

  • Private repository integration

  • Build reproducibility across environments

  • Enterprise workflows (cross-account sharing, cleanup)

The Solution: Instead of every team solving these problems from scratch, this library provides proven patterns that work reliably in production.

Key Features

  • Multi-Tool Support: Seamless integration with pip, Poetry, and UV

  • Cross-Platform Builds: Container-based builds ensuring Linux compatibility

  • Private Repositories: Built-in AWS CodeArtifact and private PyPI support

  • Command Pattern Architecture: Granular control with builder.run() simplicity

  • Enterprise Ready: Change detection, automated cleanup, cross-account sharing
