cngpac

A highly configurable package release manager

Automate changelogs, semantic versioning, npm publishing, and GitHub releases — all driven by a single config file and a pluggable pipeline.

Why cngpac?

Releasing packages involves many error-prone steps: deciding the next version, writing a changelog, bumping package.json, tagging, publishing, creating a GitHub release… Each step is a chance for mistakes.

Tools like Changesets popularized changenote-based workflows but offer limited configurability. Cngpac builds on the same philosophy with deep configuration from the ground up — every stage of the pipeline is pluggable and composable.

What it does

1. Calculate the correct semantic version bump from changenotes
2. Generate a rich changelog with commit links, PR references, and contributor attribution
3. Update package.json with the new version
4. Commit, tag, and push the release
5. Publish to npm (with provenance support)
6. Create a GitHub Release
