github-changes was convenient for auto-generating CHANGELOG.md from git commit messages, so I’ll introduce it.

Install github-changes

npm install -g github-changes

How to Use github-changes

(Example) Using github-changes to Pull Request CHANGELOG.md

github-changes -o request -r request -b master \\
--date-format '(YYYY/MM/DD)' --only-pulls --use-commit-body --auth

Before updating the request module to the latest version with npm update, I checked the Change Log and found it wasn’t updated, so I used github-changes to submit a Pull Request to CHANGELOG.md.

• Updated the Change Log for v2.88.0 · Pull Request #3008 · request/request

I specified the —date-format ‘(YYYY/MM/DD)’ option to match the format of the existing CHANGELOG.md.
