I don't know about you, but I hate writing changelogs. At the same time, a well-written changelog is incredibly useful for users of your package; not keeping a changelog (or dumping git commit histories into a file and calling it a changelog) isn't a good option.
Some people use automated tools like conventional-changelog, but those require you to keep a special git commit message format for every commit, and frankly, I hate doing that just as much.
So, I've built a little
changelog-helper; a browser interface for writing your changelogs in.
npm install -g changelog-helper
From your project directory, run
changelog-helper. It will open your browser to the interface where you can write your changelog and preview it. When you're done, click
Write to CHANGELOG.md, and your new release notes will be prepended onto your
CHANGELOG.md (or the file will be created if it doesn't exist).
