§5: Publishing

Creating and merging PRs will create new package versions that you can monitor by vising the Actions tab in Github.

Channels

• alpha: Used for manual testing in other packages
• beta: Used for UAT and testing by external consumers
• next: Everything that will be included in the next major version release

Versioning

This project uses SemVer for versioning. For the versions available, see the tags on this repository.

An beta pre-release version will be published whenever you create a PR and incremented as you update your changes. Once the PR is merged, a release version is created automatically. This is handled with semantic-release.

Major versions should have a corresponding release in Github. Click here to create a new release once your version meets acceptance criteria.

Footnotes

1. NODE_ENV must also be development, meaning this works when the app is run with npm start but not npm run prod. ↩

2. In order to run cypress tests in Firefox, set this var to 127.0.0.1 locally. ↩
