Make sure you have the latest from the main branch:
git pull origin main
Use npm version to update the version number in the package.json.
npm version {patch|minor|major} --no-git-tag-version
Then run the publish script
./publish.sh
afterwards don't forget to update the versions to be a prerelease of the next version, so if you just published 1.1.1 then:
npm version 1.1.2-dev
git push --follow-tags
