Committing

This project uses semantic release to ensure version bumps follow semver so that projects depending on it don't break unexpectedly.

In order to automatically determine version updates, semantic release expects commit messages to follow the conventional-changelog specification.

You can use the commitizen CLI to make commits formatted in this way:

npm install -g commitizen@latest cz-conventional-changelog@latest

Now you're ready to make commits using git cz.
