Summary

  • Adds a new worker-previews/ section under Workers > CI/CD docs
  • Covers three approaches to achieve DO isolation in Worker Previews:
    1. ctx.exports (recommended) — zero binding config, auto-provisioned isolated namespaces
    2. Dashboard binding — manual namespace selection via the Previews toggle in Settings > Bindings
    3. Wrangler config bindingpreviews.durable_objects.bindings with script_name
  • Includes approach comparison table, common issues, and troubleshooting
  • Index page covers Worker Previews overview, quick start, Preview Defaults, secrets management, and comparison with existing Preview URLs

Note: This is written for my own understanding of how DO isolation works with Worker Previews based on hands-on testing.
