Using uv in pre-commit

An official pre-commit hook is provided at astral-sh/uv-pre-commit.

To use uv with pre-commit, add one of the following examples to the repos list in the .pre-commit-config.yaml.

To make sure your uv.lock file is up to date even if your pyproject.toml file was changed:

.pre-commit-config.yaml

repos:
  - repo: https://github.com/astral-sh/uv-pre-commit
    # uv version.
    rev: 0.7.9
    hooks:
      - id: uv-lock

To keep a requirements.txt file in sync with your uv.lock file:

.pre-commit-config.yaml

repos:
  - repo: https://github.com/astral-sh/uv-pre-commit
    # uv version.
    rev: 0.7.9
    hooks:
      - id: uv-export

To compile requirements files:

.pre-commit-config.yaml

repos:
  - repo: https://github.com/astral-sh/uv-pre-commit
    # uv version.
    rev: 0.7.9
    hooks:
      # Compile requirements
      - id: pip-compile
        args: [requirements.in, -o, requirements.txt]

To compile alternative requirements files, modify args and files:

.pre-commit-config.yaml

repos:
  - repo: https://github.com/astral-sh/uv-pre-commit
    # uv version.
    rev: 0.7.9
    hooks:
      # Compile requirements
      - id: pip-compile
        args: [requirements-dev.in, -o, requirements-dev.txt]
        files: ^requirements-dev\.(in|txt)$

To run the hook over multiple files at the same time, add additional entries:

.pre-commit-config.yaml

repos:
  - repo: https://github.com/astral-sh/uv-pre-commit
    # uv version.
    rev: 0.7.9
    hooks:
      # Compile requirements
      - id: pip-compile
        name: pip-compile requirements.in
        args: [requirements.in, -o, requirements.txt]
      - id: pip-compile
        name: pip-compile requirements-dev.in
        args: [requirements-dev.in, -o, requirements-dev.txt]
        files: ^requirements-dev\.(in|txt)$
