The @babel/plugin-transform-modules-commonjs package transforms ES2015 (ES6) modules into the CommonJS format, enabling compatibility with older JavaScript environments like Node.js that natively support require and module.exports. Comparing versions 7.4.0 and 7.2.0, several subtle but important differences emerge for developers.
Both versions share core dependencies like @babel/helper-plugin-utils, @babel/helper-simple-access, and @babel/helper-module-transforms, indicating a consistent approach to module transformation and plugin utility. The peer dependency on @babel/core remains ^7.0.0-0 in both, ensuring compatibility with Babel 7. However, the significant distinction arises in the devDependencies. Version 7.4.0 requires @babel/core at ^7.4.0, while 7.2.0 depends on @babel/core version ^7.2.0. This means that developers upgrading to 7.4.0 of the transform modules package *must* also upgrade their core Babel dependency to at least version 7.4.0. Otherwise, incompatibilities may be encountered. The file count and unpacked size also see a shift, indicating likely internal refactoring or bug fixes, going from 6 files and 8738 unpacked size in version 7.2.0 to 4 files and an unpacked size of 8798 in version 7.4.0 . This increase in unpacked size can hint that some optimizations or fixes have been included. Finally, from a timeline perspective Version 7.4.0 was released on March 19, 2019, whilst version 7.2.0 was released near the end of 2018, so the newer version constitutes a more up-to-date state.
