📝 Walkthrough

Walkthrough

This PR adds a new updateMetadata method to the UserResource interface and its User class implementation. The method accepts UpdateUserMetadataParams containing unsafeMetadata and issues a PATCH request to /me/metadata, using deep-merge semantics where nested keys are merged and keys set to null are removed. Two test cases verify that the PATCH request includes JSON-stringified unsafeMetadata and correctly handles null-valued keys. A changeset documents the minor version bumps for @clerk/clerk-js and @clerk/shared and clarifies that only unsafeMetadata is writable via this endpoint.
