Marks common Angular packages and RxJS as external within the Vitest test runner's build configuration. This allows Vite to perform dependency pre-bundling on these libraries, which can significantly improve build and rebuild performance during test execution. The implementation introduces a constant to hold the list of packages and merges them with any externalDependencies that may already exist in the base build options, preserving user configuration.
