Minor Changes

• #16494 0968b08 Thanks @petebacondarwin! - Enable Miniflare's development registry by default and centralize path resolution

  In Miniflare v5 beta, resolve the registry from CLOUDFLARE_DEV_REGISTRY_PATH, then the unsafeDevRegistryPath constructor option, then <Cloudflare config directory>/dev-registry/v5. The default is independent of legacy Wrangler directories and is scoped to the Miniflare major version. The Vite v2 beta plugin follows this new default, while current Wrangler and getPlatformProxy() retain Wrangler's legacy default for compatibility with existing Wrangler sessions. Vite v2 and Wrangler therefore require the same CLOUDFLARE_DEV_REGISTRY_PATH to discover each other; set it for both processes when mixing these tools.

  Add enableDevRegistry: false to disable registration and discovery explicitly. Shared storage now uses the resolved default without requiring an explicit path. As before, shared storage requires an enabled registry to elect a storage owner, so combining unsafeEnableSharedStorage: true with enableDevRegistry: false is rejected. Miniflare no longer reads MINIFLARE_REGISTRY_PATH; use CLOUDFLARE_DEV_REGISTRY_PATH instead. Expose resolveDevRegistryPath() for integrations that also read registry files. Wrangler uses the effective path for its runtime configuration, initial bindings display, and Flagship active-session check, so the canonical override cannot bypass that check. An explicitly disabled Wrangler registry remains disabled.

Patch Changes

• #16499 f3c13b3 Thanks @dinasaur404! - Preserve binding error codes and names in local development

  Errors from remote bindings and from Node.js binding proxies (getPlatformProxy() and Miniflare#getBindings()) now keep their machine-readable properties, such as Artifacts' code and numericCode. Previously these properties were dropped and the error name was folded into the message (for example "ArtifactsError: Repository not found"), so code could only branch on error text during local development.

  Node.js callers also keep custom error names such as ArtifactsError. Errors from remote bindings received inside a Worker keep their properties but are still named Error.
