@commitlint/config-conventional

What is @commitlint/config-conventional?

The @commitlint/config-conventional npm package is used to enforce conventional commit messages. This package provides a set of rules that follow the Conventional Commits specification, which standardizes commit messages to make them more readable and to facilitate automatic generation of changelogs.

What are @commitlint/config-conventional's main functionalities?

Enforcing commit message structure

This code snippet is a configuration file that extends the rules from @commitlint/config-conventional. It is used to enforce a conventional commit message structure in your project.

module.exports = {extends: ['@commitlint/config-conventional']};

Linting commit messages

This command line example demonstrates how to lint a commit message using commitlint with the conventional configuration. It will check if the message follows the conventional commit format.

echo 'fix: correct minor typos in code' | npx commitlint

Integrating with commit hooks

This code snippet shows how to integrate commitlint with Husky's commit-msg hook to automatically lint each commit message before it is finalized.

husky add .husky/commit-msg 'npx --no-install commitlint --edit "$1"'

Other packages similar to @commitlint/config-conventional

standard-version

Similar to @commitlint/config-conventional, standard-version is a utility for versioning using semver and CHANGELOG generation powered by Conventional Commits. It differs in that it focuses on versioning and changelog generation rather than linting commit messages.

semantic-release

semantic-release automates the versioning and package publishing process based on semantic versioning and Conventional Commits, similar to @commitlint/config-conventional's adherence to the Conventional Commits specification. However, semantic-release encompasses the full release process, including determining the next version number, generating release notes, and publishing the package.

commitizen

commitizen is a tool that prompts developers to follow the Conventional Commits format when creating commit messages. It is complementary to @commitlint/config-conventional, which lints commit messages, whereas commitizen helps in crafting them.
