SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

uv2nix automates turning uv-based Python project workspaces into deterministic Nix derivations, enabling reproducible builds and deployments.

Core Features & Use Cases

Workspace to derivations: Generate Nix expressions for all projects inside a uv workspace.
Monorepo support: Handle multi-package repos with shared dependencies.
Nix + Python tooling integration: Works with pyproject-nix, Nix flakes, and Python packaging standards.

Quick Start

From the workspace root, run uv2nix to generate default.nix and workspace derivations, then build with nix build.

FAQPage Schema

How do I convert a uv workspace to Nix derivations for reproducible Python builds?▼

To convert a uv workspace to Nix derivations, run uv2nix from the workspace root to generate default.nix and workspace derivations, then build with nix build. This enables reproducible Python builds across environments.

Can I use Nix derivations to manage dependencies in a Python monorepo?▼

Yes, Nix derivations can manage dependencies in a Python monorepo. uv2nix provides monorepo support by handling multi-package repos with shared dependencies and generating Nix expressions for all projects inside the uv workspace.

What tools do I need to generate Nix expressions from uv-based Python projects?▼

To generate Nix expressions from uv-based Python projects, you need uv, uv2nix, and Nix/NixOS tooling, along with pyproject-nix for PyPI-like packaging. These tools work together to enable deterministic Python builds.

Does uv2nix work with pyproject-nix and Python packaging standards?▼

Yes, uv2nix works with pyproject-nix, Nix flakes, and Python packaging standards. This integration enables automatic derivation generation for UV-based Python projects and monorepos across different environments.

Why should I use Nix derivations instead of standard uv environments for Python deployment?▼

You should use Nix derivations instead of standard uv environments to achieve deterministic, reproducible builds and deployments. uv2nix automates turning uv-based Python project workspaces into these Nix derivations for consistent environments.
