We have very precise rules over how our git commit messages can be formatted. This leads to more readable messages that are easy to follow when looking through the project history.
The commit message formatting can be added using a typical git workflow or through the use of a CLI wizard (Commitizen). To use the wizard, run npm run commit
in your terminal after staging your changes in git.
Each commit message consists of a header, a body and a footer. The header has a special format that includes a type, a scope and a subject:
<type>(<scope>): <subject>
<BLANK LINE>
<body>
<BLANK LINE>
<footer>
The header is mandatory and the scope of the header is optional.
Any line of the commit message cannot be longer 100 characters! This allows the message to be easier to read on GitHub as well as in various git tools.
If the commit reverts a previous commit, it should begin with revert:
, followed by the header of the reverted commit. In the body it should say: This reverts commit <hash>.
, where the hash is the SHA of the commit being reverted.
Must be one of the following:
- feat: A new feature
- fix: A bug fix
- docs: Documentation only changes
- style: Changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons, etc)
- refactor: A code change that neither fixes a bug nor adds a feature
- perf: A code change that improves performance
- test: Adding missing tests
- chore: Changes to the build process or auxiliary tools and libraries such as documentation generation
