Automatically Validate Commit Message Convention before Commit

To automatically validate commit messages, a git hook can be used in the commit-msg stage. The hook can be created either manually or using the pre-commit framework.

Setup with the pre-commit framework

  • Create .pre-commit-config.yaml file in the root directory of your repository with following content. 
    repos:
- repo: https://github.com/qoomon/git-conventional-commits
  rev: <RELEASE_TAG>
  hooks:
    - id: conventional-commits
  • Install the pre-commit framework pip install pre-commit
  • Install the commit-msg hook pre-commit install -t commit-msg

Setup manually

  • Setup Commit Message Hook to
    • Navigate to your repository directory cd <repository-path>
    • Create git hook directory mkdir .git-hooks
    • Set update hooksPath git config core.hooksPath .git-hooks
    • Create commit message hook script and make it executable
      • touch .git-hooks/commit-msg && chmod +x .git-hooks/commit-msg
      • Open .git-hooks/commit-msg with your favorite editor and paste following script 
        #!/bin/sh

# fix for windows systems
PATH="/c/Program Files/nodejs:$HOME/AppData/Roaming/npm/:$PATH"

npx git-conventional-commits commit-msg-hook "$1"
    • Add and commit .git-hooks/commit-msg to repository

Important

Whenever you clone your repository with git hooks you need to enable git hooks once again
git config core.hooksPath .git-hooks

Release Workflow with git-conventional-commits

  • Determine version by npx git-conventional-commits version
  • Update version in project files
    • Commit version bump git commit -am'build(release): bump project version to <version>'
  • Generate change log by npx git-conventional-commits changelog --release <version> --file 'CHANGELOG.md'
    • Commit change log git commit -am'docs(release): create <version> change log entry'
  • Tag commit with version git tag -a -m'build(release): <version>' '<version-prefix><version>'
  • Push all changes git push
  • Build and upload artifacts

Integration with existing repository

If you have an large existing repo with no release tags e.g. v1.0.0, or if you want the first changelog to be tidy, you need to create a release tag first.

  • Create release tag for specific commitgit tag -a -m'build(release): 0.0.0' 'v0.0.0'
  • Push tag git push origin v0.0.0 This way npx git-conventional-commits will only considre commits based on the commit the release tag is pointing at.
