Summary

This removes packages/enhanced/src/lib/container/runtime/ChildCompilationRuntimePlugin.ts from @module-federation/enhanced.

The file was explicitly marked in-source as a previous child-compilation-based solution that is not currently used, and a repository search found no symbol or path references to it. Keeping dead runtime plugin code in the package increases maintenance surface and makes the runtime folder look more active than it is.

Deleting the file reduces unused code without changing any active import path, export surface, or runtime integration.

Validation

  • rg -n "ChildCompilationRuntimePlugin|ChildCompilationRuntime" .: no live references found outside the deleted file.
  • pnpm --filter @module-federation/enhanced run build: passed.
  • pnpm exec prettier --check .: failed due to pre-existing formatting issues in 44 unrelated files.
  • pnpm --filter @module-federation/enhanced run test: failed in pre-existing ConsumeSharedPlugin tests with isRequiredVersion is not a function, unrelated to this deletion.

Tracked ./bundler node bundle (gzip): 4.5 kB (no change)

Bundle sizes are generated with rslib (Rspack). Package-root metrics preserve the historical report. Tracked subpath exports such as ./bundler are measured separately so ENV_TARGET-driven tree-shaking is visible. Bare imports are externalized to keep package-level sizes consistent, and assets are emitted as resources.
