📄 Description

Summary

Packages with a react-server export condition (e.g. swr) get pre-bundled with a stripped-down entry in the RSC environment, breaking client imports (like useSWR) before the RSC plugin's "use client" transform can strip them.

At startup, scan the project's direct dependencies for packages declaring a react-server export condition and automatically add them to environments.rsc.optimizeDeps.exclude.

Uses createRequire for resolution so it works across all package managers.
