Using Changesets with pnpm

:::note

At the time of writing this documentation, the latest pnpm version was v5.17.3. The latest Changesets version was v2.14.1.

:::

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 changesets' init command:

pnpx changeset init

Adding new changesets

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

Releasing changes

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

Using GitHub Actions

To automate the process, you can use changeset version with GitHub actions.

In a nutshell, the action will detect new changesets on the master branch, apply them, commit the updated metadata and changelogs, and open a Pull Request. You could also publish your packages automatically.

More info and documentation regarding this action can be found here.
