Babel-jest is a crucial Jest plugin that allows developers to seamlessly integrate Babel for code transformation within their testing environments. Version 28.0.0, released on April 25, 2022, builds upon the solid foundation of version 27.5.1, released on February 8, 2022, with some notable changes that developers should be aware of.
One key difference lies in the dependencies. Version 28.0.0 updates its internal dependencies to align with the Jest 28 ecosystem. Specifically, @jest/transform and babel-preset-jest are bumped to version ^28.0.0. This ensures compatibility and access to the latest features and bug fixes within the Jest framework. Most notably @jest/types dependency has been removed. A minor difference is the file count in the distributed tarball, with 28.0.0 containing one less file than 27.5.1. This may indicate slight changes in the packaging or build process. The unpacked size of version 28.0.0 is marginally larger, suggesting possible additions or modifications to the code.
Developers upgrading to babel-jest 28.0.0 should ensure their projects are also updated to Jest 28 to avoid potential compatibility issues. Staying current with these dependencies ensures a smooth testing experience and access to the newest advancements in both Babel and Jest. Both versions maintain the same peer dependency on @babel/core (^7.8.0), preserving compatibility with existing Babel configurations.
