This action for Changesets creates a pull request with all of the package versions updated and changelogs updated and when there are new changesets on your configured baseBranch, the PR will be updated. When you're ready, you can merge the pull request and you can either publish the packages to npm manually or setup the action to do it for you.
- publish - The command to use to build and publish packages
- version - The command to update version, edit CHANGELOG, read and delete changesets. Default to

publishor not. Default totrue - cwd - Changes node's
process.cwd()if the project is not located on the root. Default toprocess.cwd()
- published - A boolean value to indicate whether a publishing is happened or not

You'll also need to add it as a secret on your GitHub repo with the name NPM_TOKEN. Once you've done that, you can create a file at .github/workflows/release.yml with the following content.

//registry.npmjs.org/:_authToken=${process.env.NPM_TOKEN}
However, if a .npmrc file is found, the GitHub Action does not recreate the file. This is useful if you need to configure the .npmrc file on your own.
For example, you can add a step before running the Changesets GitHub Action:
- name: Creating .npmrc
run: |
cat << EOF > "$HOME/.npmrc"
//registry.npmjs.org/:_authToken=$NPM_TOKEN
EOF
env:
NPM_TOKEN: ${{ secrets.NPM_TOKEN }}If you want to hook into when publishing should occur but have your own publishing functionality you can utilize the hasChangesets output.
Note that you might need to account for things already being published in your script because a commit without any new changesets can always land on your base branch after a successful publish. In such a case you need to figure out on your own how to skip over the actual publishing logic or handle errors gracefully as most package registries won't allow you to publish over already published version.

run: yarn publishIf you need to add additional logic to the version command, you can do so by using a version script.
If the version script is present, this action will run that script instead of changeset version, so please make sure that your script calls changeset version at some point. All the changes made by the script will be included in the PR.
