Humpty 🍳

Makes sure your changelogs mention your breaking changes

Intro

It's really easy to make a breaking API change to your React component and forget to release it as a major version. Humpty stops this from happening by checking what's changed in your component API, and making sure it is mentioned in your changelogs.

Usage

$ humpty --oldApi 72c5c9e0 --newApi c72257 --gitRepo ~/Repos/bengummer/humpty-mock-api

🚨 Found 1 breaking API change not mentioned in git commits (72c5c9..c72257):

Default export
  - Prop type changed: "age" was string, now number

Supported APIs and changelogs

💡 This project has just started, a pluggable API/changelog system can be added to support APIs other than React. Raise an issue to discuss! Check out the Trello board for the roadmap.

Supported API detection

• React components
  • Prop removed
  • Prop type changed
  • Prop made mandatory
  • Prop made optional

Note: React components are currently only checked in the root index.js file - this will be made more flexible soon to read the main script from package.json.

Supported changelogs

• React components
  • Commit messages containing ${propName} prop
