@changesets/pre

What is @changesets/pre?

@changesets/pre is a tool designed to help manage pre-releases in a monorepo setup. It allows you to create, manage, and publish pre-releases of your packages, making it easier to test and iterate on changes before making a stable release.

What are @changesets/pre's main functionalities?

Enter Pre Mode

This command puts your repository into 'pre' mode, where all subsequent changesets will be treated as pre-releases. The 'beta' argument specifies the pre-release tag.

npx changeset pre enter beta

Exit Pre Mode

This command exits 'pre' mode, returning your repository to normal release behavior. Any subsequent changesets will be treated as stable releases.

npx changeset pre exit

Create a Changeset

This command creates a new changeset, which is a record of changes that will be included in the next release. In 'pre' mode, these changes will be part of the pre-release.

npx changeset add

Publish Pre-Release

This command publishes the pre-release packages to the npm registry. It ensures that the pre-release versions are correctly tagged and available for testing.

npx changeset publish
