Babel-jest versions 27.4.0 and 27.3.1 serve as Jest plugins, enabling developers to leverage Babel for transforming code within their testing environments. Both iterations maintain similar core functionality, providing seamless integration between Jest and Babel. Key dependencies like chalk, slash, and graceful-fs remain consistent, ensuring continued compatibility and performance. However, notable differences arise in the specific versions of other dependencies.
Version 27.4.0 updates several @jest packages, including @jest/types to version 27.4.0 and @jest/transform to version 27.4.0, aligning them with the core Jest version. babel-preset-jest is updated to v27.4.0. These updates might introduce new features, bug fixes, or performance improvements within the Jest ecosystem. Developers should consult the Jest and Babel preset changelogs for detailed information on these changes.
In contrast, version 27.3.1 relies on older versions of these @jest dependencies, specifically @jest/types at 27.2.5 and @jest/transform at 27.3.1. babel-preset-jest uses v27.2.0. While this version offers stability and compatibility with the corresponding Jest release, it might lack the latest enhancements present in the newer dependencies. The @babel/core version allowed as a peer dependency remains the same at ^7.8.0, indicating no breaking changes concerning core Babel compatibility. Choosing between these versions depends on project-specific requirements, balancing the need for the latest features against the stability of a well-established configuration.
