Summary
This release enhances the local development experience by enabling the local explorer by default, adding R2 support, and introducing worker filtering to the explorer UI. Workflow instances also gained new control methods (pause, resume, restart, terminate) locally.
Migration Steps
- If you wish to disable the experimental local explorer UI, set the environment variable X_LOCAL_EXPLORER=false.
✨ New Features
- Local explorer UI now supports worker filtering when multiple workers share a dev registry, using a worker selector dropdown reflected in the URL via a ?worker= search param.
- Added R2 support to the local explorer, including viewing, modifying, deleting objects, uploading files, and creating directories/prefixes.
- The local explorer UI is now enabled by default during local development, accessible at /cdn-cgi/explorer to inspect D1, DO, and KV state.
- Workflow instances now support pause, resume, restart, and terminate operations during local development via methods like instance.pause(), instance.resume(), instance.restart(), and instance.terminate().
🐛 Bug Fixes
- The local explorer's Durable Object instance listing now excludes the metadata.sqlite file, preventing inflated counts and broken pagination caused by workerd's new per-namespace alarm metadata storage.
