Contributing

Pull requests are always welcome =)

The project uses standard-changelog to update the Changelog with each commit message and upgrade the package version. For that reason every contribution should have a title and body that follows the conventional commits standard conventions (e.g. feat(analyzer): Make it smarter than Jarvis).

To make this process easier, you can do the following:

Install commitizen and cz-conventional-changelog globally

npm i -g commitizen cz-conventional-changelog

Save cz-conventional-changelog as default

echo '{ "path": "cz-conventional-changelog" }' > ~/.czrc

Instead of git commit, you can now run

git cz

and follow the instructions to generate the commit message.
