Using Changesets with pnpm

note

At the time of writing this documentation, the latest pnpm version was v10.4.1. The latest Changesets version was v2.28.0.

Setup

To setup changesets on a pnpm workspace, install changesets as a dev dependency in the root of the workspace:

pnpm add -Dw @changesets/cli

Then run changesets' init command to generate a changesets config:

pnpm changeset init

Adding new changesets

To generate a new changeset, run pnpm changeset in the root of the repository. The generated markdown files in the .changeset directory should be committed to the repository.

Releasing changes

Run pnpm changeset version. This will bump the versions of the packages previously specified with pnpm changeset (and any dependents of those) and update the changelog files.
Run pnpm install. This will update the lockfile and rebuild packages.
Commit the changes.
Run pnpm publish -r. This command will publish all packages that have bumped versions not yet present in the registry.

Integration with GitHub Actions

To automate the process, you can use changeset version with GitHub actions. The action will detect when changeset files arrive in the main branch, and then open a new PR listing all the packages with bumped versions. The PR will automatically update itself every time a new changeset file arrives in main. Once merged the packages will be updated, and if the publish input has been specified on the action they will be published using the given command.

Add a publish script

Add a new script called ci:publish which executes pnpm publish -r. This will publish to the registry once the PR created by changeset version has been merged. If the package is public and scoped, adding --access=public may be necessary to prevent npm rejecting the publish.

package.json

{
   "scripts": {
      "ci:publish": "pnpm publish -r"
   },
   ...
}

Add the workflow

Add a new workflow at .github/workflows/changesets.yml. This workflow will create a new branch and PR, so Actions should be given read and write permissions in the repo settings (github.com/<repo-owner>/<repo-name>/settings/actions). If including the publish input on the changesets/action step, the repo should also include an auth token for npm as a repository secret named NPM_TOKEN.
