Merge and Release Process

Branches in use

Development

PRs should be made against and merged into the dev-5.x branch, which is set as the default branch on GitHub.

Release

Releases are currently made from the 5.x branch.

Release Process

To make a new release, follow these steps:

• Verify the development branch has all the changes desired in the release and works well
• You can test changes to the library and experiment easily with patch-package
• Once you have made changes, and after finalizing them, use npm pack to test your new, changed version of the library locally and check it works correctly
• Make and merge a final PR into the development branch that increments the version number in package.json
• Make and merge a PR from the development branch to the release branch
• Using the GitHub web UI, draft a new release using the tag name vx.x.x (replace the x values as appropriate). Use the release branch as the target, with the release name being vx.x.x (again, with appropriate numbers in place of x)
• Verify in the GitHub Actions panel for the repository that npm publish succeeded
