Migrating a plugin from Poetry to uv

This guide will help you migrate your Singer plugin from Poetry to uv.

Prerequisites

• uv

Steps

1. Use the migrate-to-uv tool to migrate your project from Poetry to uv. Run the following command in your project directory:

uvx migrate-to-uv

2. Update the build-system section in your pyproject.toml file to use hatchling:

[build-system]
build-backend = "hatchling.build"
requires = ["hatchling>=1,<2"]

3. Update your CI/CD to use uv commands instead of poetry commands. For example, replace poetry install with uv sync. You may also want to use the official setup-uv GitHub Action to install uv in your CI/CD workflow.

Example
