polymer serve

Testing

To lint:

npm run lint

npm test

Versioning & Releasing

TL;DR: Commits prefixed with fix: and feat: will trigger patch and minor releases when merged to master. Read on for more details...

The sematic-release GitHub Action is called from the release.yml GitHub Action workflow to handle version changes and releasing.

Version Changes

All version changes should obey semantic versioning rules:

  1. MAJOR version when you make incompatible API changes,
  2. MINOR version when you add functionality in a backwards compatible manner, and
  3. PATCH version when you make backwards compatible bug fixes.

The next version number will be determined from the commit messages since the previous release. Our semantic-release configuration uses the Angular convention when analyzing commits:

  • Commits which are prefixed with fix: or perf: will trigger a patch release. Example: fix: validate input before using
  • Commits which are prefixed with feat: will trigger a minor release. Example: feat: add toggle() method
  • To trigger a MAJOR release, include BREAKING CHANGE: with a space or two newlines in the footer of the commit message
  • Other suggested prefixes which will NOT trigger a release: build:, ci:, docs:, style:, refactor: and test:. Example: docs: adding README for new component

To revert a change, add the revert: prefix to the original commit message. This will cause the reverted change to be omitted from the release notes. Example: revert: fix: validate input before using.

Releases

When a release is triggered, it will:

  • Update the version in package.json
  • Tag the commit
  • Create a GitHub release (including release notes)
  • Deploy a new package to NPM

Releasing from Maintenance Branches

Occasionally you'll want to backport a feature or bug fix to an older release. semantic-release refers to these as maintenance branches.

Maintenance branch names should be of the form: +([0-9])?(.{+([0-9]),x}).x.

Regular expressions are complicated, but this essentially means branch names should look like:

  • 1.15.x for patch releases on top of the 1.15 release (after version 1.16 exists)
  • 2.x for feature releases on top of the 2 release (after version 3 exists)
