@mediamonks/commitlint-config

Set some basic conventions and rules for our commit messages using commitlint.

Note that we have not enabled the type and scope rules that are "conventional", because we don't use them. It just focuses on the basics outlined in this article on how to write good commit messages.

Installation

Install @commitlint/cli and @mediamonks/commitlint-config

npm i -D @commitlint/cli @mediamonks/commitlint-config

Create your configuration

This can be added in a lot of places (see docs), but we recommend the package.json.

{
  ...
  "commitlint": {
    "extends": ["@mediamonks/commitlint-config"]
  }
}

Set up husky

To make sure that your commit messages are validated when you are committing.

# Install Husky v6
npm i -D husky

# Activate hooks
npx husky install

# Add hook
npx husky add .husky/commit-msg  'npx --no -- commitlint --edit ${1}'
