cracks is a fantastically helpful CLI for detecting API breaking changes in your code based on your last release. This project wraps that functionality to be used in conjunction with GitHub PRs and Travis CI.
When API breaking changes are detected, pumpthebreaks will make a comment on your pull request with the error results so that everyone is aware that this pull request should result in a major release. See semver.org for more information regarding release types.
In yo travis.yml, as part of your script, add:
- if [ "$TRAVIS_PULL_REQUEST" != "false" ]; then npm i -g pumpthebreaks && pump; fi
and provide your personal access token for GitHub as an environment variable on Travis CI as GH_OAUTH_TOKEN so that pumpthebreaks can comment on your PR on your behalf.
You'll wanna put this after your coverage/testing commands so that those commands don't also use the old tests.
