What problem does it solve? Production bundles can silently ship server code to the client, duplicate generated route data across eager and lazy chunks, or include both development and production React builds when NODE_ENV is not folded. These regressions are invisible to tree-shaking and unit tests, so they need a dedicated audit before releases or after changes to the Vite plugin or public exports. ## Core Features & Use Cases - Server-leak detection: Builds all wired Cloudflare and e2e apps with the analyzer enabled and flags any server-only modules that reach the client bundle with non-zero gzip size. - Route-manifest sanity check: Verifies that the virtual routes-manifest module stays under 1 KB in the eager chunk, with trie data living only in the lazy per-router chunk. - Cross-environment duplication and React variant audit: Detects dev React builds in SSR output and large files triple-bundled across client, SSR, and RSC environments. - Use Case: Before publishing an experimental release of the router, run the audit to confirm no server code leaked, the stress-demo manifest stayed small, and chunk sizes match the 50-60 KB gzip baseline. ## Quick Start Run the bundle analysis audit across all wired apps and report any server leaks, manifest duplication, or chunk size regressions.
