GitLint
Efficient Git Commit Message Linting and Formatting
GitLint is a tool for enforcing consistent Git commit message conventions. It analyzes commit messages to ensure they follow the Conventional Commits specification and other configurable rules.
Installation
# Install globally
npm install -g @stacksjs/gitlint
# Or using bun
bun install -g @stacksjs/gitlint
We are looking to get it published as gitlint
on npm, but it's not allowing us to do so due to git-lint
. Please npm 🙏🏽
Usage
CLI
# Check a commit message from a file
gitlint path/to/commit-message.txt
# Use with git commit message hook (common use case)
gitlint --edit $1
# Show help
gitlint --help
Git Hooks Integration
GitLint can automatically install Git hooks for your repository:
# Install the commit-msg hook
gitlint hooks --install
# Force overwrite if a hook already exists
gitlint hooks --install --force
# Uninstall the hooks
gitlint hooks --uninstall
Or manually add to your .git/hooks/commit-msg
file:
#!/bin/sh
gitlint --edit "$1"
Or use with husky:
// package.json
{
"husky": {
"hooks": {
"commit-msg": "gitlint --edit $HUSKY_GIT_PARAMS"
}
}
}
Configuration
Create a gitlint.config.js
file in your project root:
// gitlint.config.js
module.exports = {
verbose: true,
rules: {
'conventional-commits': 2,
'header-max-length': [2, { maxLength: 72 }],
'body-max-line-length': [2, { maxLength: 100 }],
'body-leading-blank': 2,
'no-trailing-whitespace': 1
},
ignores: [
'^Merge branch',
'^Merge pull request'
]
}
